Separating these two cases would make fixing this crash easier. Do you have some traces that show int10 usage before/after patch or can the game be downloaded for free from some site? -- Jukka Heinonen <http://www.iki.fi/jhei/>

--with-nptl and glibc-2.3.2
by James Pellow 07 Apr '03

07 Apr '03

Hi all, After reading the comments on the list reguarding glibc-2.3.2, it appears all I need to do is ./configure --with-nptl. Today, gave this a try and am having the following error messages repeated many times when trying to link d3d8: shader.o(.text+0x19f8): In function `IDirect3DVertexShaderImpl_ParseProgram': /home/pellja/cvs/wine/dlls/d3d8/../../include/winbase.h:1932: undefined reference to `HeapAlloc' stateblock.o(.text+0x1064): In function `IDirect3DDeviceImpl_CreateStateBlock': /home/pellja/cvs/wine/dlls/d3d8/../../include/winbase.h:1932: undefined reference to `HeapAlloc' stateblock.o(.text+0x1402): In function `IDirect3DDeviceImpl_DeleteStateBlock': /home/pellja/cvs/wine/dlls/d3d8/../../include/winbase.h:1932: undefined reference to `HeapFree' stateblock.o(.text+0x14ed): In function `IDirect3DDeviceImpl_BeginStateBlock': /home/pellja/cvs/wine/dlls/d3d8/../../include/winbase.h:1932: undefined --snip-- I have had this problem for the last couple of releases... My setup is an up to date gentoo, todays wine-cvs, glibc-2.3.2 and gcc-3.2.2. on an AMD thunderbird. Any ideas? On the gentoo formums, they all say downgrade to glibc-2.3.1, and hear I read use --with-nptl, but it doesn't work... I would rather not downgrade my glibc... Thanks for your help. Sorry if this is becomming a FAQ, but it still didn't seem clear to me. James

[announce] QEMU x86 emulator version 0.1
by Fabrice Bellard 07 Apr '03

07 Apr '03

Hi, The first release of the QEMU x86 emulator is available at http://bellard.org/qemu/. QEMU achieves a fast user space Linux x86 emulation on x86 and PowerPC Linux hosts by using dynamic translation. Its main goal is to be able to run the Wine project on non-x86 architectures. Fabrice.

Both threads can happily be running at the same time - we are using clone() after all. I can currently produce this race (without my patch applied) by adding a "Sleep( 1000 )" to the USR1 signal handler in ntdll/signal_i386.c. The wineserver is convinced that the thread is suspended, but it isn't (sleeping is a bad example - assume that a context switch occurred, or heavy processing happened before the signal was delivered). this 'race' doesn't have ANY effect, because suspending a thread is not a precise operation - it doesn't matter whether 1 or 1000 instructions are executed by the thread before it stops. Windows threads don't give guarantees about thread suspension (unlike pthreads). to summarize: a) there is already a race condition in the current code - it _probably_ only triggers on SMP or heavily loaded UP. b) my patch won't make things any worse c) the race doesn't matter because Windows threads don't guarantee what happens when a thread is suspended (read Microsoft's docs - they practically say "don't use this call" for this very reason). Seeya, Adam -- Real Programmers don't comment their code. If it was hard to write, it should be hard to read, and even harder to modify. These are all my own opinions.

In the patch http://cvs.winehq.com/patch.py?id=7793 you set only : - FIXME("RAS support is not implemented !
