Wine's goals
by Francois Gouget April 2, 2003

April 2, 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.

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.

Wine
by Tuch April 2, 2003

April 2, 2003

I recently tried to install wine from src and ran into a problem. when it prompted me to enter the root password to do a "make install" I did so, and it proceeded to tell me that I entered an incorrect password. I tried this several times realizing it is possible to enter the password incorrectly, but each time gave the same result. Now I know the password was correct as I am the only user of this box and I installed Slackware 9.0 myself. As a request of your install app, I am e-mailing you this. Thanks Bill

As a global note, I think it would be appreciated breaking the patch in smaller bits... it makes it easier to track/follow what happens. For example, I don't see any reason for including the msvcrtd patches into this patch I think that Alexandre is currently integrating (bit per bit) your changes into wine. look for the patch about zeroing the request zones (which is another implementation of your structure packing), as well as local availability of the thread PID on a more minor side of things, I would keep the VALGRIND prefix in heap.c last point, using the .vg extension to the wine script may not be optimal. it won't work (as it is written) for winelib programs (which got started also thru the wine script) one solution would be (to follow your idea) to link (for a winelib app called foo) foo.vg to script wine (and change your rule something like *.vg|*/*.vg). another option would be to embed this support as an option to the wine script (like --valgrind) how are your patches doing on the "other side" (I mean valgrind's) ?

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

Fw: glibc tracker bug - installshiels

It works fine for me. ---- I'm still hanging on installshield. I copied the suggested stdole* files and rcp*4 from my win98 cd (or whatever i don't rembe now) in my system folder, but the microsoft installer 2 doesn't install correctly. It doesn't create it's directory in the common files. I tried to install it in a clean win98 pc and copy the dir, but installshield doesn't work from some apps.

Whither specmaker?
by Kevin Cousins April 1, 2003

April 1, 2003

Searching for an answer to my problem, comp.emulators.ms-windows.wine archives at google throw up a post [1] suggesting looking into tools/specmaker. Sources checked out from winehq.com CVS as of last week, updated today, have tools/specmaker as an empty directory. Where might I be able to investigate specmaker? Is specmaker still viable? FWIW, my problem is the oft-asked "How do I call functions in a Windows DLL from an ELF process?" I appreciate WineLib is an option, and have run into a number of snarls along that path: 1. I have created a .dll.so to wrap calls to the offending Windows DLL. Calls are made through static function pointers which have been initialised in the .dll.so by calls to GetProcAddress() from what would be the DllMain() function there. I've not managed to get Wine to call that DllMain() function of my .dll.so, other than through a breakpoint in the debugger, and explicitly calling the function at that time. This way, my code runs even returning from calls to the Windows DLL, but mysteriously, no output file is written! 2. I occasionally see user32.dll.so barf with a SEGV with the call stack mentioning res_146() deep during the first call to wine_dlopen(). I've also had a look at avifile, mplayer, and xine, to investigate how they do things. Linking avifile/plugins/libwin32/loader/libloader.a to my application means I can run as far as attempting to execute DllMain() on my Windows DLL before I see gut-wrenching a SEGV. What are other people doing? -- Kevin. [1]

Edit box input problem
by Brad Campbell April 1, 2003

April 1, 2003

G'day all, I'm having a strange problem with any application that uses a delphi TMaskEdit component. I have knocked up a simple test application. http://www.seme.com.au/masktest.tgz It's in Borland Delphi 4 and contains both the .exe and the source for the interested or security conscious. Can someone else run this up on their wine build and see if it's doing the same thing? Under windows, it will only accept three numeric characters, under wine I'm unable to edit the field, it accepts over 3 characters and of any type, plus the first one or two character entries create a message storm as watched with a --debugmsg +message. Also, I'm willing to have a crack at fixing this, which .dll source should I start looking at? I also tried this with native comctl32, commdlg and oleaut32 dll's just in case. Problem remains. A normal Edit component works fine, and if I remove the mask it works fine, so it must be something the in the delphi code for the TMaskEdit component that is triggering a wine bug. -- Brad.... /"\ \ / ASCII RIBBON CAMPAIGN X AGAINST HTML MAIL / \

Question about kernel32 resources
by Maxime Bellengé April 1, 2003

April 1, 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 April 1, 2003

April 1, 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
