If it is not too much effort, could you elaborate on the derived work issue. I have been thinking about trying to stub out, then work at implementing, a particular component. Rather than have someone else do the work, I am more interested in learning about doing it myself, and about any issues (legal and technical) involved. I am not asking for a complete howto here, but even a summary of the highlights would be quite valuable (to me at least). -- Thanks -- Jeff S. _________________________________________________________________ Add photos to your e-mail with MSN 8.

Configure question
by Martin Wilck Nov. 19, 2002

Nov. 19, 2002

I am thinking about some netapi32 improvements where I'd need to call the functions of the getpw/getgr family: getpwnam(), getpwent(), getgrent(), etc. Configure checks for the "pwd.h" header and getpwuid(). Must I add more checks for all the functions I use, or is it ok to assume that getpwuid() presence implies getpwnam() presence?

windres vs. wrc
by Dimitrie O. Paun Nov. 19, 2002

Nov. 19, 2002

Folks, I've just discovered (DUH!) another free resource compiler: http://www.redhat.com/docs/manuals/gnupro/GNUPro-Toolkit-98r2/5_ut/c_Usingb… This one is part of binutils. Now, like any good hacker, I hate such code duplication. Granted, I haven't looked through the code of windres, so I can't say if it's any good. However, here are some points to ponder: -- all Win32 free software projects out there use windres, not wrc -- for this reason, it is like it's more generic / better maintained -- do we want eventually to phase one of them out? -- their command line arguments are incompatible. This causes problems when trying to build portable Makefiles. Should we try to be command line compatible with windres, so we are a drop in replacement (for the .rc/.res -> .o conversion)? Any windres experiences? Comments? -- Dimi.

Command-line MS FTP clients don't support passive mode and I have heard reports that IE does not also. If that is the problem you'll have to switch to a Linux box or find a windows FTP client that supports passive.

Ah, OK. Wrong solution. But still, shouldn't the "DWORD service" parameter be popped somewhere?

VxDCall is the only register function that violates stdcall => WINAPI. But sure turning the check off in winapi_check is easy.

Possibly my last question... for a while. ;-)
by Fredrick P. Lackey Nov. 18, 2002

Nov. 18, 2002

Gentlemen, I feel really bad bothering a developers list with such basic questions, but. well. you all ARE the most responsive of everyone I've met so far. And, since you seem to hold the key to getting my @$$ of Micrsoshaft, then. well. I guess I'm sorry but I'm not. ;-) (By the way, if there is every anything I can do to repay you for your assistance and patience, consider it done.) As much as it pains me to ask, has anyone tried installing VMWare v3.x (either the Linux or Windows version) into Red Hat v8.0? If so, did you get it work? And, if so, then how? Again, my goal most definitely is to use Wine and Wine alone, however, I can't even consider moving forward unless I can use my environment for ALL of my current tasks (which includes development for M$, unfortunately). Thanx, either way. And, again, thank you for all of your help. R/S Fred www.fredlackey.com

wine commandline options
by Rick Romero Nov. 18, 2002

Nov. 18, 2002

I was playing with Pegasus Mail (silver list) to see what I could get working. It looks like it doesn't detect winsock.dll using it's own 'search algorythm, so the TCP/IP options don't get enabled - hence the (paraphrased) 'wtf?' in the silver list description. So, I tried to force Pegasus Mail to load winsock explicitly using the -Z 128 option: $wine winpm-32 -Z 128 but wine comes back with 'Unknown option -Z'. I'm not quite sure how these are getting parsed, but I see in misc/options.c parse_options() if (*p++ != '-') continue; /* not an option */ Should exit if the 2nd char isn't a - (am I right?) BUT, when parse_options returns to OPTIONS_ParseOptions() The following: /* check if any option remains */ for (i = 1; argv[i]; i++) { if (!strcmp( argv[i], "--" )) { remove_options( argv, i, 1, 0 ); break; } if (argv[i][0] == '-') { MESSAGE( "Unknown option '%s'\n\n", argv[i] ); // OPTIONS_Usage(); } } Still picks up '-' as an invalid option. My first thought would be to stop checking for options after the 1st and 2nd chars are not '-' (ie. after the Win32 program name), but I'm not sure if that's correct. Any thoughts? (FYI, no, the option didn't make Pmail work.) Rick -- -- Rick Romero IT Manager Valeo, Inc. ph: 262.695.4841 Sussex, WI. fax: 262.695.4850 Rick(a)valeoinc.com

Dual boot solves everything?
by Fredrick P. Lackey Nov. 18, 2002

Nov. 18, 2002

Gentlemen, First of all, thanks to everyone with your input so far. I've now been able to get IE v6.0 up and running as well as a few other less important applications. Which brings me to a few more questions. 1. Since it is possible to use native DLLs with applications, can one assume that on a dual boot machine with Win98 SE2 and Red Hat v8.0 that it would only be necessary to install the desired application under Windows, then add native DLLs to the Wine config file to get [almost] *any* Windows application to function? 2. Each time I launch a program, a black window appears that seems to make up the "shell" (for lack of a better term) for that instance of the application. This window is always somewhere around 800x600 pixels. Is there any way to not show this window and/or get the size to be something else? I am running in 1600x1200 resolution and only using half of the screen is frustrating. 3. Is there an easy way within Linux/Wine to determine what native DLLs the application should/could use? Thanx again, Fred Lackey Orlando, Florida

Yes, I'm leaning in that direction as well the more I think about it. However, I don't think it is enough. It will work for the implemented VxDCall that pops the stack itself, however it will not work for unimplemented VxDCalls since they will not clean up the stack correctly AFAICS. Anyway, if so it has been wrong a long time (so long that I don't notice the warning from winapi_check any longer :-), so I wonder why it wasn't noticed by anybody else running an application using VxD calls.

I'm not sure, it might be the other API(s) that are wrong or that VxDCall is a special case. That why I haven't dared changed anything. The problem with VxDCall is that is have multiple entries under different external names. ./dlls/kernel/kernel32.spec: 1 stdcall -register -i386 VxDCall0(long) VxDCall ./dlls/kernel/kernel32.spec: 2 stdcall -register -i386 VxDCall1(long) VxDCall ./dlls/kernel/kernel32.spec: 3 stdcall -register -i386 VxDCall2(long) VxDCall ./dlls/kernel/kernel32.spec: 4 stdcall -register -i386 VxDCall3(long) VxDCall ./dlls/kernel/kernel32.spec: 5 stdcall -register -i386 VxDCall4(long) VxDCall /dlls/kernel/kernel32.spec: 6 stdcall -register -i386 VxDCall5(long) VxDCall ./dlls/kernel/kernel32.spec: 7 stdcall -register -i386 VxDCall6(long) VxDCall ./dlls/kernel/kernel32.spec: 8 stdcall -register -i386 VxDCall7(long) VxDCall ./dlls/kernel/kernel32.spec: 9 stdcall -register -i386 VxDCall8(long) VxDCall Searching on the Internet reveals this page: http://www.mbs.spb.ru/kb/w32mbr.htm According to this page VxDCall[0-8] really should be stdcall. ---8<--- /* Kernel32 W32-caller prototypes */ DWORD WINAPI VxDCall0(DWORD service); DWORD WINAPI VxDCall1(DWORD service, DWORD); DWORD WINAPI VxDCall2(DWORD service, DWORD, DWORD); DWORD WINAPI VxDCall3(DWORD service, DWORD, DWORD, DWORD); DWORD WINAPI VxDCall4(DWORD service, DWORD, DWORD, DWORD, DWORD); DWORD WINAPI VxDCall5(DWORD service, DWORD, DWORD, DWORD, DWORD, DWORD); DWORD WINAPI VxDCall6(DWORD service, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD); DWORD WINAPI VxDCall7(DWORD service, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD); DWORD WINAPI VxDCall8(DWORD service, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD); ---8<--- and this ---8<--- vxdcall.def LIBRARY KERNEL32 EXPORTS VxDCall0(a)0 @1 VxDCall1(a)8 @2 VxDCall2(a)12 @3 VxDCall3(a)16 @4 VxDCall4(a)20 @5 VxDCall5(a)24 @6 VxDCall6(a)28 @7 VxDCall7(a)32 @8 VxDCall8(a)36 @9 ---8<--- However something with VxDCall is wrong nether the less. WINAPI functions (read: __stdcall) functions expects that the callee cleans up the argument stack and the number of arguments is different depending on which function is called. Looking at VxDCall (and what it calls) in win32/device.c I see that the implemented VxDCall pops the stack. However the unimplemented VxDCalls doesn't even though they might have gotten some arguments. This means AFAICS that VxDCall corrupts the stack in such cases... So I'm pretty convinced that something is wrong however I don't think you patch is the solution to the problem. It might possible be part of a solution though... Any suggestions?

DUMMYSTRUCT is defined as nothing if the compiler supports nameless structs. GNU C++ was mistakenly believed by me to support nameless structs. I didn't check however, I have check now and it seem like no version of GNU C++ does. :-( Not that it really needs to support it since you could get the same effect with "dummy" structs/classes and inheritence, but then I really can't see any particular reason not to support it since makes at least as much sense (if not more) in C++ to have unnamed structs as in C... Anyway, there is a patch in wine-patches that fixes the problem and since it as I said is always possible to "fake it" in C++ there is no great need to ask the GNU C++ developers the fix the problem either...

Problem running Anstoss2 under Wine
by Adrian Bunk Nov. 17, 2002

I'm trying to run Anstoss2 (a five years old German soccer simulation - I'm only interested in the strategic part of the game) under Wine. I tried the Debian package of the 20021031 Release and a self-compiled package of a 20021116 CVS snapshot.

CoInitialize
by steve.lustbader＠philips.com Nov. 16, 2002

Nov. 16, 2002

One of the threads in my app calls CoInitialize, expecting it to return S_OK (in fact, it's followed by an assert statement requiring that it returns S_OK). When I run it in Wine, however, CoInitialize returns S_FALSE, implying that this thread has already initialized the COM library. Other threads call CoInitialize, but this is the first time that this thread calls it. Does Wine initialize COM differently from Windows? Are the other threads' calls to CoInitialize screwing up this thread's call? -Steve

However, when I saw that not much happend despite getting code from cabextrect under LGPL I thought that perhaps people were having trouble on how to create a new DLL in Wine and how to extract the declarations from the Microsoft header without creating a derived work. I have done it many times before so thought why not do it... So I very happy that somebody is intrested in continuing. PS. If anybody have some other DLL that they wish to implement but don't now how to do it, don't hesitate to ask me to create a stub DLL with related headers.

Font selection - please review
by Shachar Shemesh Nov. 16, 2002

Nov. 16, 2002

Hi all, I am thinking of submitting the attached patch. The problem is that I am not comfertable with the location I added it. As far as I could tell, there is nowhere in the whole of Wine where the selected language is matched with the charset to be used by default. This is what this patch comes to amend. There is a slight awkwardness that is inherent to the Win32 API, in which, in order to create the default font, you zero out a LOGFONT struct, fill in the struct length, and call "CreateFontIndirect". Looking at the resulting struct, however, reveals that what you have just asked for is a ANSI_CHARSET font. It appears that windows correctly understands that this is an uninitialized LOGFONT, apparently based on the fields tested. The reason I am not sure this is the correct place, however, is that there seem to be system-wide default fonts, and I'm not 100% sure why, but they are ANSI (read - latin) only. I am willing to delve deeper into that part of the code, but I need to understand it better first. I was wondering whether anyone else on this list is aware of the reasons. Shachar License: LGPL Changelog: Shachar Shemesh <winecode(a)sun.consumer.org.il> objects/font.c * Added a function to convert language to charset. * Added code to select the apropriate charset in case the charset was not specified (DEFAULT_CHARSET or uninitialized LOGFONT).

wineoss MIDI help
by Jeff Smith Nov. 16, 2002

Nov. 16, 2002

I have several programs that require MIDI support. When I try to run them I get: err:midi:OSS_MidiInit ioctl on midi info for device 0 failed. This comes from line 274 of dlls/winmm/wineoss/midi.c When this error is encountered, the /dev/sequencer is closed and OSS_MidiInit returns. I have determined that my card indicates having two midi devices. Only the second supports the SNDCTL_MIDI_INFO ioctl. But midi.c never gets to the second because of the first. I have tried some simple hacks, but have not accomplished anything notable. Anybody got any insights as to a simple fix? If not, would I be better off delving into wineoss or getting the first MIDI device of the emu10k1 driver to handle MIDI_INFO? ;-) -- Jeff S _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus

And although we don't want to fall into "dependency hell", one has to consider we are trying provide a layer of compatibilty for an OS that is known for the same. So I think selective dependencies, as Shachar mentions, are perfectly reasonable. I don't mind a dependecy on FAM, but I could be biased, as I already installed it for the associated KDE functionality. If inserted as a conditional dependency, the fallback position if it is not present is no worse than the current position.

COM Enhancement patch
by Christian Costa Nov. 15, 2002

Nov. 15, 2002

Hi all, I've sent a patch for ddraw COM management, I did not have any comments and the patch has been rejected. Could someone tell me if something is wrong or lacking? Christian. PS: I've joined a small doc that explains how to use objects with multiple interfaces. This docs is based on what has been done before with the ddraw code plus the enhancement I did. --------------------------------------------------------------------------------- - COM OBJECTS MANAGEMENT - --------------------------------------------------------------------------------- 1) Definitions: --------------- a) Object classes An object class is a structure wich defines the data of an object and all the interfaces that act on the object data Example : struct ObjectClass { INTERFACE 1; INTERFACE 2; ............ INTERFACE N; DATA; } ; typedef struct ObjectClass ObjectClass; b) Objects An object is a instance of an object class. Example : An object is created as follows : ObjectClass* object = malloc(sizeof(ObjectClass),...) c) Interfaces An interface is a way for an application to interact with an object. It contains a pointer to a virtual table plus some other data than can help objects management. An interface is a structure, which is used internally, that can be defined with the INTERFACE macro : #define INTERFACE(iface) \ struct { \ iface interface; \ /* VTABLE */ LPVOID object; \ /* pointer to the object the interface belongs to */ } To add a field to the interface, just add it in this macro. For example, we could embed the version number inside an interface or a magic number to check if the interface's pointer points to a real interface. And, off course, modify some macros or create new ones to make use of them. 2) Implementing COM objects: --------------------------- a) Declaring a COM object with multiple interfaces To declare interfaces in a COM object the ICOM_VFIELD_MULTI must be used for each interface as shown below: struct IDirect3DImpl { /* IUnknown fields */ ICOM_VFIELD_MULTI(IDirect3D); ICOM_VFIELD_MULTI(IDirect3D2); ICOM_VFIELD_MULTI(IDirect3D3); ICOM_VFIELD_MULTI(IDirect3D7); DWORD ref; /* IDirect3D fields */ IDirectDrawImpl* ddraw; LPVOID private; }; b) Creating an object Just declare an pointer to an object and allocate the memory for it. Example: IDirect3DImpl* object = malloc(sizeof(IDirect3DImpl),...) c) Initializing interfaces It is done with the ICOM_INIT_INTERFACE(object_pointer, interface_name, virtual_table) ICOM_INIT_INTERFACE(object,IDirect3D, VTABLE_IDirect3D); ICOM_INIT_INTERFACE(object,IDirect3D2,VTABLE_IDirect3D2); ICOM_INIT_INTERFACE(object,IDirect3D3,VTABLE_IDirect3D3); ICOM_INIT_INTERFACE(object,IDirect3D7,VTABLE_IDirect3D4); d) Retreive an object from within an interface's function If we consider the function : IDirect3D_AddRef(IDirect3D iface,.......) To retrieve a pointer to an object within the function, both followings macro are used : 1) ICOM_OBJECT(object_class,iface) This macro return an pointer to the object, the value is of object_class* type Example: IDirect3DImpl* d3d = ICOM_OBJECT(IDirect3DImpl,iface); 2) ICOM_THIS_OBJECT(object class,iface) It simply declares a This pointer and initialize it with the object address. IDirect3DImpl* This = ICOM_OBJECT(IDirect3DImpl,iface); e) Sharing functions between multiple interfaces In the case where a function does no have to do specific actions depending on the interface, you can share directly a function. Example : If we consider the function : IDirect3D_AddRef(IDirect3D iface,.......) The different virtual tables would be : VTABLE_IDirect3D = {......,IDirect3D_AddRef,....); VTABLE_IDirect3D2 = {......,XCAST()IDirect3D_AddRef,....); VTABLE_IDirect3D3 = {......,XCAST()IDirect3D_AddRef,....); VTABLE_IDirect3D7 = {......,XCAST()IDirect3D_AddRef,....); Note that this is possible because the ICOM_OBJECT can retreive the object's pointer without knowing the interface involved. f) Thunking interface Interface thunking enable changing from one interface to another. The following macro COM_INTERFACE_CAST(impltype, ifnamefrom, ifnameto, ifaceptr) performs this task. impltype = object class ifnamefrom = interface type we have ifnamefrom = interface type we want ifaceptr = pointer to the interface to cast return = pointer to the casted interface Interface thunking is a another way to shared a single function across different interfaces but as shown below this is required only when structures must be translated, interfaces returned casted or to handle prototype change : Example: You want to share the IDirect3D_CreateDevice across all IDirect3DX interfaces (with X above 1 because a device in Direct3D is created in a different way). IDirect3D2_CreateDevice(IDirect3D2* iface,.....) is the only one implementation of the function. The others are thunks to the IDirect3D2_CreateDevice. IDirect3D3_CreateDevice(IDirect3D3* iface, .....,LPDIRECT3DDEVICE3 *lpdevice, LPUNKNOWN lpUnk) { IDirect3DDevice3 *dev; IDirect3D_CreateDevice(ICOM_INTERFACE_CAST(IDirect3DImpl,IDirect3D2,IDirect3D3,iface),.....,&dev); *lpdevice = ICOM_INTERFACE_CAST((IDirect3DImpl,IDirect3D3,IDirect3D2,device) } IDirect3D7_CreateDevice(IDirect3D7* iface, .....,LPDIRECT3DDEVICE7 *lpdevice) { IDirect3DDevice2 *dev; IDirect3D_CreateDevice(ICOM_INTERFACE_CAST(IDirect3DImpl,IDirect3D2,IDirect3D7,iface),.....,&dev); *lpdevice = ICOM_INTERFACE_CAST((IDirect3DImpl,IDirect3D7,IDirect3D2,dev) } Here, we have to deal with a returned interface and a prototype change. The VTABLE should be: VTABLE_IDirect3D2 = {......,IDirect3D2_CreateDevice,....); VTABLE_IDirect3D3 = {......,IDirect3D3_CreateDevice,....); VTABLE_IDirect3D7 = {......,IDirect3D7_CreateDevice,....); Note that there are few functions that need this, for the others, thunks are not necessary and the way described in e) must be preferred. g) Getting an specific interface of an object With the ICOM_INTERFACE(implobj, ifacename) macro, any interfaces can be retreive from an object. implobj = pointer to the object ifacename = interface name we want return = pointer to an interface Example: IDirect3DImpl* object; ............ IDirect3D3* iface_d3d3 = ICOM_INTERFACE(object,IDirect3D3) h) Calling an COM object functions from another If a function is shared across multiple interfaces, you should write: IDirect3D3_CreateDevice(IDirect3D* iface,.....) { ICOM_THIS_OBJECT(iface); ................. IDirect3D_AddRef(ICOM_INTERFACE(This,IDirect3D),.....); ................. } If you know the nature of iface (i.e. thunking is used or the function is used in only one interface), you can write : IDirect3D3_CreateDevice(IDirect3D* iface,.....) { ICOM_THIS_OBJECT(iface); ................. IDirect3D3_AddRef(iface,.....); ................. }

Wine without any X11 environment
by Michael Riedel Nov. 15, 2002

Nov. 15, 2002

Hello, is it possible to use wine in a telnet session to start a (command line) windows application? I get the error that x11drv can't connect to a display (which is correct). I'm also not very sure that the windows program itself does not perform some graphic related queries (there were some fixme messages when I tried to use 'ttydrv'). Any ideas? Is there any workaround to use a dummy display or whatever? Thanks, Michael --

Your compiler seems to issue more warnings than mine :-/ It is good to see these patches are really reviewed. The lenW thingy is really embarrassing for me.
