Re: Small 'let's prevent a crash' fix
by Lionel Ulmer 02 Jul '02

> This does not fix the real problem (ie why does this DC not have a font even > if the application called a 'SelectObject' on it), but well, it cannot harm > to be more verbose and to prevent crashes if possible :-) OK, found the 'error' : the problem comes from the fact that I am using client-side fonts (aka XRender) : so the 'font' part of the physDev structure is always '0'. And that also means that we cannot use as is the glXUseXFont function. So basically, I need to implement it myself using 'GetGlyphOutline' (should not be that hard to do :-) ). Now my question : is 'GetGlyphOutline' always working even when not using client-side fonts ? If yes, I will completely remove the call to glXUseXFonts (I know, in that case, fonts displayed by OpenGL will be different by the one displayed by X, but well, ...) and always use the manual 'GetGlyphOutline' function. And I will try at the same time to remove all GLX calls from wgl.c and put them in special X11DRV escapes to have a real X11 free wgl.c file (ie for example, creating an OpenGL context would be a special escape for the X11DRV as it's basically something that is in GLX).

Re: heads up: wine 20020605 broken on FreeBSD, workaround included
by Gerald Pfeifer 02 Jul '02

02 Jul '02

[ I'm now also Cc:ing this to the Wine developers, thus the full-quote. In fact, all non-GLIBC platforms seem to be affected by this bug! ] Based on your pointer, I believe I found the problem. In aclocal.m4 we have: AC_DEFUN([WINE_CHECK_ERRNO], [AC_CACHE_CHECK([for reentrant libc: $1],[wine_cv_libc_r_$1], [AC_TRY_RUN([int myerrno = 0; char buf[256]; int *$1(){return &myerrno;} main(){connect(0,buf,255); exit(!myerrno);}], wine_cv_libc_r_$1=yes, wine_cv_libc_r_$1=no, wine_cv_libc_r_$1=yes)]) AS_IF([test "$wine_cv_libc_r_$1" = "yes"],[$2],[$3])]) which, in configure, becomes: int myerrno = 0; char buf256; int *__error(){return &myerrno;} main(){connect(0,buf,255); exit(!myerrno);} That is, instead of an array of 256 characters, we have one character, and the invocation of connect() is definitely incorrect. Could someone more familiar with autoconf please have a look at this?

Are there any patches in waiting to disable the use of ALSA in the configure script ... or is this not needed?

IsDialogMessageA/W question
by Sander van Leeuwen 01 Jul '02

01 Jul '02

Hi, Is there a specific reason why unprocessed messages in IsDialogMessage don't get dispatched? Experiments in Windows 2000 show this is not (always) correct. It seems all messages passed on to IsDialogMessage are dispatched and it always returns 1. IsDialogMessage doesn't call DispatchMessage, but the function called internally by DispatchMessage. Changing the behaviour to match Windows 2000 fixes at least one problem I noticed in an MFC application (button getting stuck when using the spacebar). There's not much information in MSDN about this function, so I can't say if IsDialogMessage always behaves like this. Sander

Re: Using win dll with wine
by psuchomel＠volny.cz 01 Jul '02

01 Jul '02

I can not simply transfer this code from Windows (under them it is compilable and working) to Wine, because this code is bridge beetwen my Java app and this dll. Because it depends on Windows natives of Sun JVM, it can not be directly run under Linux. My problem: How to brand (?) part of Wine, to be able use this dll f.e. with Qt Canvas or X11 rendering?. The example shows only some of the simpliest parts of this one, primary it is used as native rendering engine (and this engine exist only as dll for Windows, I do not expect there will be version for Linux in suitable time for me).

Usind win dll with wine
by psuchomel＠volny.cz 01 Jul '02

01 Jul '02

Hi wine gurus I have some dll, I want to run under Linux. I try to study Wine docs, but, if I say the truth, I did not make me clever so much. Please, could you help me port this part of win code (extracted from my java <--> cpp bridge) under Linux? Petr //define dll handler HINSTANCE hInst = NULL; //define entry in dll typedef char* (_pascal * GLL_version)(); //here is some call //load library if( hInst == NULL ) hInst = LoadLibrary("mylib"); if( hInst == NULL ) return; //get proc address FARPROC proc = GetProcAddress(hInst, "GLL_VERSION"); //and call it if (proc != NULL) printf("%s", (char*)(GLL_version)proc()); //free handler FreeLibrary(hInst); hInst = NULL;

Bug #829 triggers lock-up in Baldur's Gate
by Ian D. Stewart 01 Jul '02

01 Jul '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 After further research, it looks as if the lock-up in Baldur's Gate is being triggered by an unsupported API Call. Here is the pertinent error message from Wine: fixme:ddraw:DIB_DirectDrawSurface_Blt dwFlags DDBLT_WAIT and/or DDBLT_ASYNC: can't handle right now. This fixme is only encountered during game 'movies' (including resting and death scenes). I have a full logfile if anyone is interested.
