Useful document on critical sections
by Mike Hearn 24 Dec '03

24 Dec '03

Hi, I found this article: http://msdn.microsoft.com/msdnmag/issues/03/12/CriticalSections/ There are two points of interest that we don't seem to cover: * RtlpWaitForCriticalSection will NOT block if the process is shutting down and the wait is on the loader lock. I've seen a fair few times when an app deadlocks on shutdown on the loader lock - could this be the cause? * The loader lock is stored at offset 0xA0 in the PEB. I doubt this is important, but now the info is published murphies law says one day an app will try and get to it directly. thanks -mike

More exec-shield problems
by Mike Hearn 24 Dec '03

24 Dec '03

Hi, When /proc/sys/kernel/exec-shield is set to 1, the StarCraft installer crashes. (it doesn't matter what the -randomize option is set to). It appears then that exec-shield screws things up in more subtle ways than just stopping us mapping the binary. The details of the crash are that the game allocates some memory using RtlAllocateHeap, uses MultiByteToWideStr to fill it, then calls GetStringTypeW on the memory, which crashes with an access violation. There is a way to link wine such that execshield will be switched off, some linker flag. Does anybody know how to integrate that with the Wine build system? thanks -mike

I tried it out, seems ie6 setup fails with current CVS, says something on low mem or lack of space. Mandrake Linux 9.2 with all patches and latest CVS wine, Hatky. __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/

newbie wine developer question
by Zimler Attila 24 Dec '03

24 Dec '03

Hi, Since I'm new in developing wine please forgive me if I ask a question that is answered earlier (I tried to search an answer for my questions, but I did not found.) 1) Should I report fixme's in bugzilla? (I guess, not, but I'm not sure). 2) I would like to fix some fixme (which I can reproduce), but I don't understand a lot of thins. (I'm new to wine, but not new to C). Could somebody help me to start involved in the development process? Attila ZIMLER

Problems building wine
by iain 24 Dec '03

24 Dec '03

When building wine using the wineinstall script I'm getting the following errors make[2]: Entering directory `/usr/local/src/wine-20031212/dlls/glu32' gcc -shared -Wl,-Bsymbolic,-z,defs glu32.spec.o glu.o glu32.dll.dbg. o -o glu32.dll.so -L../../libs/wine -lwine -L/usr/X11R6/lib -lSM -lICE -lXxf86dga -lXxf86vm -lXrandr -lXrender -lXv -lXext -lX11 -lGL -lGLU - L../../libs/port -lwine_port -lm -lc glu.o: In function `wine_gluNewTess': /usr/local/src/wine-20031212/dlls/glu32/../../include/winbase.h:1949: undefined reference to `HeapAlloc' glu.o: In function `wine_gluDeleteTess': /usr/local/src/wine-20031212/dlls/glu32/../../include/winbase.h:1949: undefined reference to `HeapFree' collect2: ld returned 1 exit status If I disable the opengl stuff, then it gets to the ddraw directory and gives similar errors (but about 1000 more of them). This is with both CVS head from today and with the 2003-12-12 snapshot tarball. Anyone got any ideas? iain

They come with apps because the vendors of those apps have a license from M$ to redistribute them.

I'm sure it's illegal, but that's how things are. Anybody (DOJ?) could sue them on that point, are you going to have a go? As I don't think you developed the script with a M$ tool that comes with a license that allows you to distribute M$ dlls for whatever platform, this is irrelevant. > If they start claiming that the MFC DLL can only be used on genuine > Windows, then we have much bigger problems than having to pull a > convenience script - that would make many programs unrunnable on Wine > (but of course they cannot say this, so that's not a problem). No, if an app is developed for windows using M$ tools/sdk/compiler, but a user runs the app on wine, it is perfectly legal. Well, technically some M$ lawyer may say it isn't, but nobody would be liable. > Well this is what Microsoft claim, but the distinction has never really > been spelled out. MSN Messenger comes with Windows too - does that make > it an OS component? I'm not sure. The antitrust case about this is not over, actually Bill testified at it recently, and maybe D.C. and the ten suing states will win. If they do, there may be builds of windows without OE/IE/MSN, but I don't think there will be OE/IE/MSN that can legally run without a windows license. > I have an old copy of MSVC++ lying around here somewhere anyway, so I > guess I do have a license.

This seems to the cause of the problem: 0009:Call kernel32.CreateFileA(4a0f69f0 "C:\\Programmi\\Ultima Online\\\\stadifi0.mul",80000000,00000001,00000000,00000003,10000080,00000000) ret=004ff693 0009:Ret kernel32.CreateFileA() retval=00000158 ret=004ff693 0009:Call kernel32.CreateFileMappingA(00000158,00000000,00000002,00000000,00000000,00000000) ret=004ff712 0009:Ret kernel32.CreateFileMappingA() retval=0000015c ret=004ff712 0009:Call kernel32.MapViewOfFile(0000015c,00000004,00000000,00000000,00000000) ret=004ff78f 0009:Ret kernel32.MapViewOfFile() retval=00000000 ret=004ff78f 0009:Call user32.MessageBoxA(00000000,005bdf70 "There is not enough memory to continue execution. If you do not have virtual me"...,005be05c "Out of memory",00000000) ret=004d949b so the problem should be into MapViewOfFile (kernel/virtual.c), retval=00000000 (NULL) is a failure. Because the return NULL is only in an if, the problem is inherited from NtMapViewOfSection, that is in ntdll/virtual.c. This function seems to be a lot complex, I need to dig it to found the problem. -- Flameeyes <dgp85(a)users.sourceforge.net> You can find LIRC for 2.6 kernels at http://flameeyes.web.ctonet.it/

wine-20031212 defaults to Thai ui?!
by Dan Kegel 24 Dec '03

24 Dec '03

This is hilarious... I just built wine-20031212 from source (using tools/wineinstall), and... all the menus are in Thai. Even if I run winefile, or a real copy of notepad.exe. Even if I set LANG=C before running. WTF? - Dan

Problems with Ultima Online: Age of Shadows [Textbox glitch + out of memory error]
by Flameeyes 24 Dec '03

24 Dec '03

Hi all! I was trying to run Ultima Online: Age of Shadows (latest patchlevel after autopatch), but I have some problems. The first problem is actually a glitch, in autopatcher, when the textbox is moved at end, the text is hide, because it moves as first character of the textbox the after-the-last character of the text in it. The second is a big problem: when starting the client, it gives an out of memory error. I can't find where the problem is because I don't know for sure which trace channel has the functions for memory statistics. If someone has an hint for me, I'll investigate better and try to fix it. -- Flameeyes <dgp85(a)users.sourceforge.net> You can find LIRC for 2.6 kernels at http://flameeyes.web.ctonet.it/

> What about people who redistribute those apps in turn? But they aren't using them in there own app, so they aren't creating a derivate work. Only the vendor (In the case of the script you) needs a license. In any case you can't just take the dlls from an app, you must find one that allows you to distribute them in a derivate product. > I seriously doubt you have to write every piece of your code in a > project using MS tools in order to be able to redistribute a DLL. Even > if the license did say such a preposterous thing, it could certainly be > ignored. certainly not, but you must at least partially write it with a M$ tool that allows you to distribute the dlls, and again I remember reading that you must develop for windows. dll-files stays illegal, I think the best option is to use the users windows cd. Also it will make the install a little bit faster, as it won't have to download anything. Ivan.
