Anyone compiled Borland OWL (Object Windows Library) with winelib ?

by Grzegorz Prokopski

Hi ! I am unable to find this information in wine-devel archives, so I decided to ask here. Q1: Have You heard about anyone who compiled Borland OWL (Object Windows Library) based project with winelib ? Yeah - I know it is an old library and Borland C++ 5.02 is the last version released a few years ago and without future updates. Anyway I have a project which IS written in OWL and need to check how hard will it be to make it working under Linux without rewriting it all. I belive I have the sources for complete OWL of course. Q2: With You expirience what would You say to that statment: If my OWL-based program works under Wine it should be convertable to winelib. How true is that statment ? Q3: I have read docs about using winelib and seen that there is MS Visual C++ mentioned many times. Does MS VC++ have some kind of support in winemake or in winelib itself ? Does OWL case differ much from MS VC++ ? Thank You for Your answers. Grzegorz Prokopski

re: dde problems

by Josh Duncan

Eric, thanks for the pointers. I removed the ms versions of the user32, kernel32 dlls. I have attached a log file, containing the last ~100 lines of wine execution. (the command I ran was "wine --debugmsg +dde,+relay --managed ./LOGOS.EXE") am I doing something wrong if wine locks up my computer about half of the time that I try running this app? sometimes I can go back to a virtual console and kill the wine processes(which in turn kills X, annoying but not so bad since xdm kicks in), but often I have to reach for the power button. --Josh On Tue, Oct 30, 2001 at 07:45:05AM -0500, wine-devel-request(a)winehq.com wrote: > Send wine-devel mailing list submissions to > wine-devel(a)winehq.com > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.winehq.com/mailman/listinfo/wine-devel > or, via email, send a message with subject or body 'help' to > wine-devel-request(a)winehq.com > > You can reach the person managing the list at > wine-devel-admin(a)winehq.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of wine-devel digest..." > > > Today's Topics: > > 1.

I would like to > try the same but I don't see how to do it. I guess you don't know about VNC then. Here's a description of VNC. VNC is a pretty cool open-source application which lets you access a computer remotely, kind of like X but different :-) It is composed of two parts, a server and a client. The command above starts an VNC X server. This X server is not using any graphics card because it is not actually displaying anything. It just uses a chunk of memory to store the 'screen'. Because of that you can use about any pixel representation. In the above I specified that I wanted a 800x600 screen in 16 bits per pixel with the red, green and blue components in BGR order. Once you have this server, you can start the client as 'xvncviewer :1'. This connects to the above VNC server and creates an 800x600 window that shows you what is displayed in that X server. The client can be run on the same computer or on another. Because the client/server protocol involves exchanging bitmap chunks the client is very simple and can run on about any platform. So you can access the above VNC server from an Windows computer if you want. There is also a VNC server for Windows. And this leads to one of the most interesting applications of VNC: remotely controlling a Windows computer. From another Windows computer, from any Unix platform, I believe there's even a client for PalmOS! Anyway, by playing with the -depth and -pixelformat options you can test Wine as if it were running into all sorts of X servers. > Also, if you use vnc to test, did you consider the possibility that vnc > could have a bug somewhere ? There's always that possibility but the results I get with VNC (based on XFree 3.3.6) are consistent with those I get from the neomagic&permedia drivers of XFree 4.1.0. [...] > I had (of course) a number of problems with your app. > First on my current computer - a Mandrake 8, with Xfree 4, > your procedure ran fine until it tried to link the thing and then it > reported that WinMain was missing.

Yes. > What is strange is that on both of my computers the display > of your app is the same with or without my patch. No line > exchanged that I can see. This probably means that you have a 16bpp rgb565 screen. Which seems normal. It also means that the Dib is a bgr888 Dib which does not exist in Windows. So something weird is happening. Here are the interesting kind of lines: trace:bitmap:X11DRV_DIB_SetImageBits Dib: depth=24 r=ff0000 g=ff00 b=ff trace:bitmap:X11DRV_DIB_SetImageBits Bmp: depth=16/16 r=f800 g=7e0 b=1f This tells us that the Dib is a 24bpp dib and that it is an RGB dib, the only kind of 24bit DIB in Windows. What tells us that it's an RGB DIB is the r,g,b masks: the red color is encoded in the high bits of the 24bit value: 0xff0000. Then you hace the green, 0xff00, and the blue, 0xff, hence the rgb888 shorthand. Similarly the 'Bmp', i.e. an XImage, is a 16bpp rgb image. Here you will notice that the mask for the green color, 0x7e0, uses 6 bits instead of just 5. This gives you the rgb565 denomination. Finally we are in SetImage so we are converting the Dib into a Bmp, i.e. from rgb888 to rgb565 so we will call Convert_888_to_565_asis (since both are rgb). Now I suspect that with your application the Dib masks don't look like the above. Actually I have a buffer overflow patch to send for the new DIB code. I don't think it's related but then, who knows. I will try to send it tomorrow morning. > > As for The Sims, if you can also check the -debugmsg +bitmap output > >and make sure it's coherent. > > I don't have The Sims...

problems with dde, I think...

by Josh Duncan

Hi all, I'm a little new to the list, so please be forgiving if I'm asking old questions. I've tried to do some research on the net and list archives to see if my questions have been answered before. I'm trying to run a program called Logos, which is a reference system for Biblical texts and other various study materials. It has a two-(independent)-windowed type interface, with a list of reference materials in one window("library"), and a workspace-type window containing subwindows with the texts of individual books. I can get the "library" window to show up when running wine, and the initial "quick tip" window, but when I click the close button of the tip window wine encounters an exception. I believe the exception is in user32.dll, in the ddeuninitialize16 function. This is going from my memory of the one time I was able to attach to the wine process to catch the exception. I attempted copying the kernel32, user32 dll's from a win98 machine into my wine dir, but this did not help. after doing this, I could not run winedbg either, as it exits giving me the following error: err:win32:PE_fixup_imports No implementation for kernel32.dll.0(wine_get_unix_file_name) imported from winedbg, setting to 0xdeadbeef This error occurs even after removing the two dlls. If anyone can give me advice about how to fix this, I'll try to post up the winedbg results of running the program(backtrace, et al) I know that some people have mentioned dde being broken between apps, I don't know if this is the case for this app, because when I was able to do a winedbg "walk process" it only listed one w-process, with 4 w-threads running. I have attached my wine config file, any advice would be greatly appreciated. (Also, if this email should have gone to the wine-users list, please let me know) I'm using the wine-20011029.i386.rpm from LinuxEasy, linked off of the winehq.org download page. sincerely, Josh Duncan not that it matters, but a pic of the two windows I can produce are at http://www.msmd.net/logos.jpg I'd try and show a pic of the other window, but the system gets so unstable that it can hard-lockup the machine, I think this is a cpu-spinning-in-signal handler problem but I couldn't get you a log right now to prove it.

I had (of course) a number of problems with your app. First on my current computer - a Mandrake 8, with Xfree 4, your procedure ran fine until it tried to link the thing and then it reported that WinMain was missing.

I guess that when you speak of red and blue exchanged, you mean that in one of these blocks the red and blue lines are exchanged, right ? What is strange is that on both of my computers the display of your app is the same with or without my patch.

by Simon Britnell

I had an idea for using poll or select (rather than calculating expected play time and using a timeout) in audio.c The idea is to have a thread that sits on a select and dispatches a synthetic wine event (ie. we'd make up a WM_DSP_READY event) when the select returns. wodPlayer could then do an infinite wait and the select could be turned on or off when starting and ending playing. >From my relatively naive view a generic mechanism like this (ie. one that converts async IO selects into wine events) would be a good feature to have from a performance and code tidiness point of view. One caveat is that we'd need to ensure nothing evil happened if somebody sent the synthetic event from somewhere other than the select waiter. Comments?

If I apply your patch, then I see that the red and blue are exchanged when I run vnc as: vncserver :1 -geometry 800x600 -depth 16 -pixelformat bgr565 Without the patch everything is fine. I also checked the formula and I see nothing wrong with it (as long as you are on a little endian computer, but you don't have a big endian x86, do you? ;-). So the question is why doesn't it work on your system. Can you run The Sims (I assume it's with that the problem happens) with a +bitmap trace? Then look for cases where either the bmp or the dib has "depth=24". Then check the masks to see if they make sense. For example, do they match what you know of your X server. You may also put a trace in Convert_888_to_565_reverse and check that it is invoked at the right time. Do they have a bgr888 dib (unsupported in windows AFAIK, but, except for 1 or 2 shortcuts, supported in Wine)? Maybe it is the DIB masks that are wrong. Also it would be great if you could run my test application and check whether it displays fine. The line to watch for is the sixth line (rgb888 dib to 565 rgb/bgr bmp and back). I attached it to this email. Here is how to compile and run it: mkdir dib cp dib.c dib cd dib ~/wine/tools/winemaker . ./configure --with-wine=$HOME/wine make ./dib (note: don't run winemaker . in your home directory!)

It loads fine under Windows - however, both dependancy walker and the Nt quick viewer are not happy with it (one displays that there is a format error in the exe, the other loops and finally crashes) The web site says that this executable is compressed with a tool called UPX. This seems to be the reason for the problem, as the original program is compiled with Ms VC++ - not a very exotic tool. I think that a fix could be to detect a corrupted header in dump_exports and to not try to display anything if numberoffunctions is not coherent with the export section size. I tried a hack for that and virtualdub got further; however, I see that it is trying to load avicap32.dll and this is not going to work - even under Linux ;:-) Gerard

struct thread in server/thread.h

by Gerald Pfeifer

In server/thread.h we have a definition of struct thread. Unfortunately, though, this clashes with struct thread as defined in /usr/include/sys/thread.h on FreeBSD 5.x and probably other systems (Solaris) as well. How should this be addressed? Would any of you mind fixing this? (If it's okay to just rename struct thread to struct winethread, I'm volunteering to handle that, else it'd be great could one of the experts have a look!)

Wine and Starcraft

by geschrader

I've been pecking away attempting to track down why the current wine build won't run Starcraft. When it starts up I get the effect that I playfully refer to as the TSOD (Technicolor Screen Of Death). What I've found is that if all of the references to gdi_display in X11DRV_DDHAL_SetPalEntries( ) are replaced with thread_display( ) then it actually starts up and looks pretty good. However, the keyboard and mouse don't work so this is at best a partial fix. I'm pretty sure that this is on the right track since X11DRV_XF86DGA2_CreatePalette( ) uses thread_display( ) to make the palette that is eventually given to X11DRV_DDHAL_SetPalEntries( ). The only other function in dlls/x11drv/x11ddraw.c that uses gdi_display is X11DRV_DDHAL_DestroyPalette( ). Should thread_display( ) be used there also? How is gdi_display related to the display returned by thread_display( )? Both are used in quite a few places but they're obviously not the same thing. Can anybody give me some hints on what might be happening with the keyboard and mouse? Thanks much, ges

FindWindow, WaitforSingleObject and Deadlock

by Uwe Bonnes

Hallo, I reported before, some applications of the quicklogic suite starts some watchdog application and hangs at this state. I tracked this down to the following sequence of events: - master application starts, sets up an event and resets the event - master application starts the watchdog - as soon as CreateProcess return, the Master application calls WaitForSingleObject with infinite timeout on that event - watchdog application starts and calls FindWindow. This is translated in a GetWindowText Call and finally SendMessageW (WM_GETTEXT) is called - Master application never awakes from waiting for the WaitForSingleObject Event and so never processes the SendMessage and Findwindow in the watchdog never returns I found two things relates to this deadlock in the API description: For WaitForSingleObject: "Use caution when calling the wait functions and code that directly or indirectly creates windows. If a thread creates any windows, it must process messages. Message broadcasts are sent to all windows in the system. A thread that uses a wait function with no time-out interval may cause the system to become deadlocked" so the latter behaviour seems right. But GetWindowText seems to expect such a deadlock: "If the target window is owned by the current process, GetWindowText causes a WM_GETTEXT message to be sent to the specified window or control. If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. If the window does not have a caption, the return value is a null string. This behavior is by design. It allows applications to call GetWindowText without hanging if the process that owns the target window is hung." Sending the WM_GETTEXT only for local windows in the FindWindow loop makes the application continue and at some point the event is triggered. How should wine handle that case? Sould the caption be stored on the server? I it perhaps already? Bye Uwe Bonnes bon(a)elektron.ikp.physik.tu-darmstadt.de Free Software: If you contribute nothing, expect nothing --

ReadFile behaviour on COMs

by Mike McCormack

Hey Uwe, There is still a number of problems with the COMM code that i am slowly fixing. They are: * comm ports opened without FILE_FLAG_OVERLAPPED don't use (any) read and write timeouts (patch in the works) * comm timeouts don't work 100% correctly * WaitCommEvent only works for EV_RXCHAR (difficult to solve correctly) Sounds like your problem might be related to #2. There are a few special cases for the values in the COMMTIMEOUTS structure that aren't being dealt with at the moment. Could you please post a -debugmsg +file,+comm trace and i'll have a look at it on Monday. Additionally, if the software is available online somewhere, please post a link to it.

problem with virtualdub.

by Roger Fujii

there seems to be a funky problem with virtualdub (http://virutaldub.sourceforge.net) Get differing results between solaris and linux, but both seems to fail before the app comes up. Under solaris, it seems like something is screwed up with the loader - when it tries to load the binary, it dies in dump_exports because what's at pe_exports is just garbage. Not sure where it's dying under linux (probably the same place) - don't have a devel environment there (yet). Nothing unusual seems to happen before it gets there (both solaris/linux binaries run sol.exe and other stuff just fine). My suspicion is that the IMAGE_DIRECTORY_ENTRY_EXPORT data isn't pointing to what wine thinks is there, but would like someone who knows more about the loader to say something.... can anyone help shed more light onto this? -r

Ok, how about this: Each system parameter has "is_loaded" flag which shows whether the parameter is loaded or not. Parameters, stored directly in SysParametersInfo are loaded from registry only when they are requested and the flag is "false", after the loading the flag is set to "true". On interprocess notification of the parameter change the corresponding parameter flag is set to "false". The parameter will be reloaded when it is requested the next time. Parameters, backed by GetSystemMetrics are processed differently. These parameters are always loaded. They are reloaded right away on interprocess change notification. We can't do lazy loading because GetSystemMetrics returns its values from system metrics array and we don't want to complicate this function. I'm going to implement the flags as a bit array. Index constants for this array will be defined separately. >>I'll think about it more.

This way they would be > accessible from other processes. Thank you for the idea. Are there any existing implementations of communication between Wine processes I can use as an example? Disregard the patches "SystemParametersInfo / GetSystemMetrics", "SPI_GET/SETBORDER". I'll implement the discussed above changes and resubmit them. Do you still think it is better don't affect X settings from Wine? Please let me know. While we are on this - what about other my patch - "hello5.c"? It fixes a warning and an error message I got when I tried to compile hello5.c. Andriy Palamarchuk __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!

ReadFile behaviour on COMs

by Uwe Bonnes

Hallo, somebody showed me an application speaking to a device connected to the serial port. The application failed after some successfull communication steps. As the protocoll is available in some other (open source programm) we could see that the program requested two bytes from the device , but ReadFile only delivered one byte (with that byte beeing the right one of the expected two byte sequence). I suspect ReadFile to be the culprit. While the api description tells to read all requested bytes ( beside of real errors), our implementation happilies returns fewer bytes than requested. In the case of COM devices, all timeouts of the SetCommTimeout structure should be checked two. Anyone with an implementaion for that?

Hi Andreas, i had a bit more free time, so i tracked down the rendering problem in NetTerm a bit more. The problem occurs after SelectVisRgn16 is called with the same region as that currently selected in the DC. (eg. dc->hVisRgn == hrgn ). I made a dodgy patch to fix the problem by incrementing the reference count of the region in this case, but i don't know how to fix it properly, because i don't know much about region handling. With the dodgy patch, NetTerm's windows paints properly. Perhaps perhaps you or somebody has a better way to fix the problem?

Yes, cursor handling has some problems right now. It also needs to be a lot more clever about setting the cursor on child windows, and not walk the full list of top-level windows on every SetCursor. It will be fixed eventually, but it's not my top priority right now. -- Alexandre Julliard julliard(a)winehq.com

cursor visibility problem

by Ove Kaaven

In Alexandre's new windowing architecture, we have in dlls/x11drv/window.c, line 119, this: attr->cursor = X11DRV_GetCursor( display, GlobalLock16(GetCursor()) ); Problem: what if ShowCursor(FALSE) is called to hide the cursor *before* the window was created? Yup, GetCursor still returns the current (arrow) cursor, so the new window gets associated with a visible cursor, though the app would expect the cursor to remain hidden. Diablo II is currently known to suffer from this problem... it has too many cursors visible. I haven't come up with a very clean solution to this... ideas?
