Although this may duplicate effort, I am familiar with several strange combinations of exception handling that I know work with Visual C++ 6.0; I will put them a test program for you. You can never have too many test programs, right?

[announce] QEMU x86 emulator version 0.1
by Fabrice Bellard April 7, 2003

April 7, 2003

Hi, The first release of the QEMU x86 emulator is available at http://bellard.org/qemu/. QEMU achieves a fast user space Linux x86 emulation on x86 and PowerPC Linux hosts by using dynamic translation. Its main goal is to be able to run the Wine project on non-x86 architectures. Fabrice.

Clearly c) because that will work properly even when doing hotplugging of pcmcia cards and doing interactive dialup to an isp. Might want to cache it for 10 seconds or something, and you might need to worry about what happens when programs are reading the reg entries *while* an interface is changing. (heh.) BTW there is a system call getifaddrs on many flavors of Unix that does this kind of query, and there's a library implementation of it for linux. See http://www.kegel.com/dkftpbench/dkftpbench-0.45/getifaddrs.c http://www.kegel.com/dkftpbench/dkftpbench-0.45/getifaddrs.h The registry code should probably just call this function. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Any DCOM experts?
by Bill Medland April 2, 2003

April 2, 2003

Hi guys For the next part of the work I am doing I am trying to figure out if there is any way that the DCOM part of one of our products is going to work under Wine at the server end. I am not having much success so far and I was wondering if anyone knows whether this is because I don't have things set up properly or if it is because of some inherent known lack of functionality. To start the ball rolling I was working with MSDN's DCOMTST test program pair. I managed to get that working using the local server (after adding the definition of IStream to the registry) but am having no luck getting the client under Wine to talk to the server under Win98. In fact the client side doesn't even seem to send out a single TCP/IP packet. (Aside - Nice demonstration of lazy Microsoft code; in their error reporting they call FormatMessage, ignore the return code and somehow print the returned error message, even when one hasn't been allocated; I guess it only works under Windows because the print routine traps the access violation) I am currently running native ole32 and native rpcrt4. The builtin rpcrt4 fails on a call to unimplemented RpcServerInqDefaultPrincName but I don't understand why it is even calling that; why does it think I have Netware only and why does it think this is a server process. Anyone an expert in any of this stuff? -- Bill Medland ACCPAC International, Inc. medbi01(a)accpac.com Corporate: www.accpac.com Hosted Services: www.accpaconline.com

Wine's goals
by Francois Gouget April 1, 2003

April 1, 2003

I propose the following WineHQ patch to present and clarify Wine's goals. I'm submitting this to wine-devel first to get a feel of whether that would be a good addition and whether that sounds reasonable and accurate enough. Index: templates/en/about.template =================================================================== RCS file: /home/wine/lostwages/templates/en/about.template,v retrieving revision 1.7 diff -u -r1.7 about.template --- templates/en/about.template 24 Mar 2003 22:49:03 -0000 1.7 +++ templates/en/about.template 30 Mar 2003 02:35:46 -0000 @@ -29,4 +29,70 @@ <a href="mailto:julliard(a)winehq.com">julliard(a)winehq.com</a>. For a list of current developers, see the <a href="?page=who">Wine Who's Who</a>.</p> + +<h1>Wine's Goals</h1> + +<p>As mentionned in many places, the primary goal of Wine is to make it +possible to run Windows applications on x86-based Unix systems. But there is +often confusion as to what this covers. So let's clarify things a bit: + +<ul> + <li>Wine does not try to be a better Windows than Windows. What this means + is that Wine will not try to extend, improve or 'fix' the Windows API in + an attempt to lure developpers into using it. While we think that it is + important to provide a way to reuse the legacy Windows applications that + are out there, we feel that for new developments there are better APIs + than Win32. + + <li>Wine Is Not a (CPU) Emulator. So no, we will not integrate a CPU + emulator in Wine any time soon. However we will do what we can to make it + possible to integrate Wine into a CPU emulation environment that would + provide the regular Unix services that Wine depends on. In such a scheme + both Wine and the Windows application would be run in that environment. + Two candidates that come to mind are <a + href="http://fabrice.bellard.free.fr/qemu/">QEMU</a> and + <a href="http://www.transitives.com/tech_overview.htm">Dynamite</a> from + <a href="http://www.transitives.com/">Transitives Technologies</a>. + + <li>Wine's goal is to provide replacements for just those DLLs and APIs + that are needed to run Windows applications. This means that we will not + provide replacements for DLLs that are always shipped together with an + application. This also means that implementing an API that no application + ever uses is not a priority. Similarly, until there are applications out + there that use the Win64 API, it will not be a priority. That being said, + we will certainly try to keep our options open and to improve our API + coverage as we can. + + <li>Making it possible to use Windows device drivers or VxDs on Unix is not + part of Wine's goals. Device drivers don't use the same API that Windows + applications do, and run in ring 0 instead or ring 3. To make it possible + to use them on Unix, one would have to hack the kernel, implement a + completely different API. In other words, this would be a completely + separate project. However, if you want to reuse Windows drivers on + non-Microsoft operating systems we recommend that you have a look at + <a href="http://www.reactos.com/">ReactOS</a>. + + <li>Wine is not an operating system or a desktop environment. So writing + device drivers, file or window managers that look like Windows, are not + part of Wine's goals. If you are interested in those, the best would be to + contribute to the <a href="http://www.kernel.org/">Linux</a>, + <a href="http://www.freebsd.org/">FreeBSD</a> or + <a href="http://www.reactos.com/">ReactOS</a> kernels, or to the + <a href="http://www.gnome.org/">Gnome</a> or + <a href="http://www.kde.org/">KDE</a> desktop environments. You will get + the added benefit that your contribution will then be usable by everyone, + not just by Wine users. + + <li>Wine's focus is on Unix operating systems, and to some extent Linux + because that is what most of our developpers are using. However we welcome + ports to other architectures such as + <a href="http://www.reactos.com/">ReactOS</a> or + <a href="http://bewine.beunited.org/">BeWine</a>, and will try to make + it possible for them to reuse as much of Wine as possible. After all, + reimplementing the Windows API is a big enough task that it is best if we + can all work together on it. +</ul> + + <p> </p> + -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ War doesn't determine who's right.

A few questions on the mingw port.
by Steven Edwards April 1, 2003

April 1, 2003

Hello Everyone, First I want to thank everyone for the help they have given me in dealing with my bad spelling, lack of grammer and not following the rules when working to get most of wine built for mingw. I'm trying to do a little house keeping with Wine and ReactOS and had a few changes/questions that could make my and the ReactOS teams life a little easyer with the port. 1. Can we set --disable-win16 CFLAGS=-DWINE_NOWINSOCK" to be default when building under Mingw? I tried to write a configure patch for this a while back but never could get the bastard to work. Once this option is removed all we will be left with is ./configure to configure wine for mingw. None of the WINE networking stuff will really work for anyone working with mingw and I dont expect that to change anytime soon. Without this flag anything that include winsock.h or winsock2.h will puke when building on Windows. I know that WINE on linux will need win16 for a while due to older installers that are 16bit but for the mingw port thats kind of not important. 2. Can we set a conditional option to not build winegcc and winewrap? These are not needed on Windows as they are only used to port mingw applications to winelib. Due to the use of Unixisms in these programs (fork, waitpid, etc) they wont build. Now I know we could stub fork and wrap waitpid to wait but its kind of pointless and I can see one day when someone will ask why these dont work on windows even though we build them. IMHO they just shouldnt get built for us. winegcc.c: In function `spawn': winegcc.c:86: warning: implicit declaration of function `fork' winegcc.c:89: warning: implicit declaration of function `waitpid' winegcc.c:92: warning: implicit declaration of function `WIFEXITED' winegcc.c:92: warning: implicit declaration of function `WEXITSTATUS' gcc -DWINE_NOWINSOCK -Wall -mpreferred-stack-boundary=2 -gstabs+ -Wpointer-arith -o winegcc winegcc.o -L../libs/port -lwine_port winegcc.o(.text+0x1a3): In function `spawn': g:/src/wine-dev/wine/tools/winegcc.c:86: undefined reference to `fork' winegcc.o(.text+0x1d2):g:/src/wine-dev/wine/tools/winegcc.c:89: undefined refere nce to `waitpid' winegcc.o(.text+0x202):g:/src/wine-dev/wine/tools/winegcc.c:92: undefined refere nce to `WIFEXITED' winegcc.o(.text+0x211):g:/src/wine-dev/wine/tools/winegcc.c:92: undefined refere nce to `WEXITSTATUS' 3. Exclude WINEserver. This is a fun one. I took a look at this a while back a was able to get about 80% of it to compile native on windows. Before we can even get wineserver to build/link on mingw we still have the same problem a cygwin port has and that is what to do with the get/set thread_context stuff. Also from all I have read a mingw port would require a major redesign because of the signal/pipe usage. I looked at porting some of the stuff to windows sockets a while back and decided I still cant program well enough and I have more interesting things to do like work on ReactOS. =P 4. This may be more a mingw problem rather then something with WINE but I figured I would ask while I was making noise. When I try to build the regression tests under mingw with gcc-3.x I am getting this error. If I dont include wines libmsvcrt.a it goes away. do the exit functions in wine and mingws source not agree? gcc registry.o testlist.o -o advapi32_test.exe -L../../../dlls -ladvapi32 -lke rnel32 -lntdll -L../../../libs/wine -lwine -L../../../libs/port -lwine_port -lm ../../../dlls/libmsvcrt.a(ds00443.o)(.text+0x0): multiple definition of `atexit' C:/mingw/bin/../lib/gcc-lib/mingw32/3.2.1/../../../crt2.o(.text+0x40):crt1.c: fi rst defined here ../../../dlls/libmsvcrt.a(ds00319.o)(.text+0x0): multiple definition of `_onexit C:/mingw/bin/../lib/gcc-lib/mingw32/3.2.1/../../../crt2.o(.text+0x60):crt1.c: fi rst defined here make[1]: *** [advapi32_test.exe] Error 1 make[1]: Leaving directory `/g/src/wine-dev/wine/dlls/advapi32/tests' make: *** [tests] Error 2 At some point I will do documentation for Mingw on MSYS/Cygwin <g> Thanks Steven

Question about kernel32 resources
by Maxime Bellengé March 31, 2003

March 31, 2003

I am currently working on the EnumSystemLanguageGroups/EnumLanguageGroupLocales functions. I have finished everything but there is one thing I don't know. The different language group names are stored in the kernel32.dll resources in a string table. They are indexed from 1 to 17 in the win2k/winxp kernel32 dll. However, in wine it seems these ID are used. So I am wondering how can I workaround that. I can't change the ID for the groups because they are defined in winnls.h from 1 to 17. At the present time I have a version ready to work but with the group names not stored in the resources (so only one language is possible). Do I have to change the kernel32 resources ( a lot of work) or does anyone have an idea ? Thanks Max -- Maxime Bellengé <maxime.bellenge(a)laposte.net>

Problem with debugging: XIO: fatal IO error 0 (Success) on X server ":0.0"
by Juraj Hercek March 31, 2003

March 31, 2003

Hi, I have troubles with debugging winelib applications. This is what makes me unhappy: --- $ gdb wine (gdb) r notepad Starting program: /usr/local/bin/wine notepad XIO: fatal IO error 0 (Success) on X server ":0.0" after 187 requests (187 known processed) with 0 events remaining. Program exited with code 01. --- I'm getting similar results with winedbg (running "winedbg notepad") - there is just bunch of debug outputs before the error is printed. However, this happens only when I'm running winedbg from outside wine directory (checked out from cvs). It works when I'm running winedbg from wine directory. I was digging inside wine and problem occurs somewhere in MODULE_DllProcessAttach() function. This lead me to assumption that problem is probably caused by incorrect paths to libraries, which couldn't be found then. I think I should mention that also wineinstall failed because regedit couldn't find "programs/regedit/regedit.exe.so" (this file is definitely there) so I had to run regedit to insert winedefault.reg into registry manualy - I needed to copy winedefault.reg file to /tmp which is accessible from inside wine system as drive E:\. My working environment is mdk-9.1 with XFree86 version 4.3.0, native nvidia driver doesn't work, the same with nvidia driver v. 41.91). If you have any idea what could be wrong with my linux box, please let me know. I prefer gdb for debugging since I can use ddd with gdb. Thanks. --Juraj
