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 April 7, 2003

April 7, 2003

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 April 7, 2003

April 7, 2003

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.
