It takes up a lot of space, and really the _same_ options are available on the _same_ page.

We already have news. It's WWN. Adding > announcements that don't get updated as often as WWN seems lame. Leave > that to other news sites. I beg to differ. WWN is more like a magazine. It is wandeerful, and has a good purpose, but that it's not for announcement. People don't wait a month to read the latest news, they watch TV or read the newspaper. The WWN appears weekly (sometime lest often), and is concerned mainly with development topics). An Announcement section would be updated whenever something important (from a user standpoint) happens: -- A new Wine version is released -- A new WWN is released -- An important event happened in the community So the two differ in all aspects (WWN vs. Announcements) 1. Audience: Developers vs. Users 2. Update Strategy: Weekly vs. Real Time 3. Content Focus: Development Issues vs. Events And the proof is in the pudding: most major project sites have different sections for the two. See www.gnome.org, www.kde.org, www.gimp.org, etc. For better or worse, people _expect_ things organized in a certain way. Like the "File" menu to the left. Even if we think our idea are better, we should follow the Principle of Least Surprise in these matters, unless we can make a _strong_ case against it. In this instance, it seems to me it makes sense to follow the status quo. -- Dimi.

Another minor bug

March 24, 2003

I dont have time to patch this right now but maybe someone else does. When building import libs on mingw because we have to link to libwine in winebuild for wine_get_cs winebuild cant find libwine.dll. $ make PATH="../libs/unicode:$PATH" ../tools/winebuild/winebuild -o advapi32/advapi32. spec.def --def advapi32/advapi32.spec make: *** [advapi32/advapi32.spec.def] Error 128 Thanks Steven

We were all quite concerned about it until somebody reported a workaround; see http://www.winehq.com/hypermail/wine-devel/2003/02/0260.html The workaround is to give the command export LD_ASSUME_KERNEL=2.2.5 before running Wine (and probably before running configure, too). (This is documented in each distro's beta release notes, e.g. http://distro.ibiblio.org/pub/Linux/distributions/redhat/beta/phoebe/en/os/… ) Have you tried this yet?

The right fix is for Wine to adapt to the new threading model in glibc2.3 (not 3.2, I think), which is far superior to the old one. See http://www.kegel.com/c10k.html#threads.nptl > So, consider that every linux distribution will be shipped with the new glibc, > and that there will be really a few windows programs that can work without > thread support.... well... i'd think about give priority to solve this one. The changes needed are deep. Alexandre has started on them, but given the workaround, it can probably wait a bit.

nvidia crashes?
by Mike Hearn March 24, 2003

March 24, 2003

Hi, Often when a program fails, I'll get a crash inside libGLcore (with the nvidia drivers), backtrace looks like: (gdb) bt #0 0x40e0a208 in __nvsym12888 () from /usr/lib/libGLcore.so.1 #1 0x00001a76 in ?? () #2 0x4202b162 in exit () from /lib/i686/libc.so.6 #3 0x400ab79f in ExitProcess () at ../../scheduler/process.c:1440 #4 0x0100279b in ??

I'm not sure why it'd crash like this, I haven't touched my video configuration for a while, and everything else seems stable. Is there any way to stop wine from loading opengl related code? thanks -mike -- Mike Hearn <m.hearn(a)signal.qinetiq.com> QinetiQ - Malvern Technology Center

Well, certainly. To be honest, the situation is a bit more complicated. I haven't been doing any active work on the Mozilla port, my interest in the port is as a starting base for a port to Wine. This may sound odd, but for various reasons (of which just being cool is not least important), I'd like to compile the Win32 port of Mozilla under Wine in Linux. Needless to say, such ports are not trivial, but I set out to make them a lot simpler, so that we make it practical for people to port their Win32 app to Linux via Winelib. To that end I started created a MinGW-compatible build environment in Wine. Thus, porting to Wine will become a two step process: first port to MinGW, then port to Wine. It is easy to see that this approach is a lot more evolutionary, and the steps are simpler. Moreover, you have intermediate working code (the mingw port) which is also very important, not to mention that smaller number of things that change from under you in each step (in the mingw port, you only have to deal with the build tools changing, while the wine port, given that I can provide mingw-compatible tools in Wine, it's just the OS that changes). Ideally, if everything works according to the plan, the above process looks like so: A. Port MSVC/BCC app to MinGW 1. Create GNU Makefiles 2. Deal with difference between cl/bcc and gcc 3. Get working versions of the app under MinGW B. Port from MinGW to Wine 1. Copy source code to a Linux box, run dos2unix on it 2. Change #include directives from #include "some\dir\file.h" to #include "some/dir/file.h" 3. Change file/dir name capitalization to match the one on disk NOTE: Changed (2) & (3) are scriptable, and we already have a tool that takes care of them. Most importantly, they are portable between all ports so a common source code can be maintained. Needless to say, this is paramount, few people have the resources to maintain different sources. 4. Change the Makefile as follows: + ifndef WINE CC = gcc CXX = g++ WRC = windres + else + CC = winegcc + CXX = wineg++ + WRC = wrc + endif Again this change is portable between ports, so a common build system can be maintained. The winegcc/wineg++ tools already work, but they are not ready. They mainly lack -shared support for generating DLLs, but they already proved useful in porting a number of apps (http://24.103.33.114/wine/Winelib-Apps.html) or toolkits (http://www.dssd.ca/wine/Wine-Fun.html#wxwindows) This should give people a better idea why I think command line compatibility between tools is important. However, to get back to the topic of this message, I was interested in the Mozilla port to MinGW only as a starting point form my efforts toward a Winelib port. As such I haven't actually worked on it, so I don't have the environment handy to test the changes. I've posted the patch to the Mozilla bug, and hopefully someone will give it a try. If not, I'll test it, but it will take a little while to get everything up to speed. Another way is to post a test .rc file that was experiencing the problem before, would that be useful? -- Dimi.

Thunking?
by Mike Hearn March 24, 2003

March 24, 2003

Hi, Does anybody know what could cause this error? err:thunk:_loadthunk (commctrl.dll, Cctl1632_ThunkData16, comctl32.dll): Unable to load 'commctrl.dll', error 2 I checked, I don't haev comctrl.dll anywhere. I'm trying to get IE6 to work on an "out-of-the-box" Wine install, ie trying to move to a completely WineHQ setup rather than the winehq/crossover setup I was using before. I was under the impression that thunking was only used for 32/16 bridging, and IE6 is a 32bit app, so I don't really understand why it's trying to load this library using LoadLibrary16... does anybody have some tips? thanks -mike -- Mike Hearn <m.hearn(a)signal.qinetiq.com> QinetiQ - Malvern Technology Center

Janitorial W->A dlls/gdi/printdrv.c (help!)
by Tony Lambregts March 24, 2003

March 24, 2003

I have been banging my head against this one for a while and need some feedback about a problem I am having. I have attached the patch to convert StartDocA to call StartDocW instead of the other way around. This patch results with StartDocW looking as follows INT WINAPI StartDocW(HDC hdc, const DOCINFOW* doc) { INT ret = 0; DC *dc = DC_GetDCPtr( hdc ); TRACE("DocName = '%s' Output = '%s' Datatype = '%s'\n", debugstr_w(doc->lpszDocName), debugstr_w(doc->lpszOutput), debugstr_w(doc->lpszDatatype)); if(!dc) return SP_ERROR; if (dc->funcs->pStartDoc) ret = dc->funcs->pStartDoc( dc->physDev, doc ); GDI_ReleaseObj( hdc ); return ret; } The problem I am having is with this line. if (dc->funcs->pStartDoc) ret = dc->funcs->pStartDoc( dc->physDev, doc ); With my patch in place I get the following error printdrv.c: In function `StartDocW': printdrv.c:82: warning: passing arg 2 of pointer to function from incompatible pointer type so obviously dc->funcs->pStartDoc points to a function that expects DOCINFOA* as its second parameter but I am at a loss on what to do.

ImageList - my findings
by Vitaliy Margolen March 24, 2003

March 24, 2003

For past few days I was trying to figure out what is the problem with corrupt bitmaps. Here is my findings: 1. _read_bitmap does is not work right. The for() loop where it's restructuring original bitmap from multi-row into single-row. 2. Windows creates DIBSection to keep original bitmap so it could be saved as is. This is not used that often. However development tools do use it. For example: Delphi. I have few questions before making any hacking: - Why do we use single row bitpams versus multi-row like native? - Why we not creating DIBSection? -- Best regards, Vitaliy Margolen
