Hallo,
I am trying to run the WebPACK_42wp30_full_installer.exe
: http://direct.xilinx.com/direct/webpack/42wp3/\
: WebPACK_42wp30_full_installer.exe
(a 110 MByte Download).
Running it crashes quite early, while testing the debug channels:
err:font:ReadFontDir Can't open directory "/usr/X11R6/lib/X11/fonts/TrueType"
err:font:ReadFontDir Can't open directory "/usr/X11R6/lib/X11/fonts/TT"

It seems the location of the debug channels is picked up from the ebx
register
Wine-dbg>disass 0x40710c52
0x40710c52 WINPROC_CallWndProc [../windows/winproc.c:231] in user32: call 0x40707c70 WIN_RestoreWndsLock [/home/wine/wine/dlls/user/../../windows/user.c:183] in user32

0x40710c60 WINPROC_CallWndProc [../windows/winproc.c:232] in user32: testb $0x8,0x0(%eax)
I wonder what can trash the testing of the debug channels. I ran with +heap
to look for heap corruption, but couldn't find something.
Uncommenting the offending code
> if (TRACE_ON(relay))
> DPRINTF( "%04lx:Ret window proc %p (hwnd=%p,msg=%s,wp=%08x,lp=%08lx) retval=%08lx\n",
> GetCurrentThreadId(), proc, hwnd, SPY_GetMsgName(msg, hwnd), wParam, lParam, retvalue );
makes the application proceed.
Bye
