Whither specmaker?
by Kevin Cousins 01 Apr '03

01 Apr '03

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 01 Apr '03

01 Apr '03

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 01 Apr '03

01 Apr '03

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 01 Apr '03

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
