Which C++ compiler did you use? With too old compiler (or the wrong options) the layout of your COM virtual tables is probably wrong (though I'm not sure the execution got that far). With a more recent compiler (gcc 2.96+), the C++ ABI is not supported by either gdb or winedbg so that no debugger is usable to debug. Well, at least you cannot put breakpoints on methods, view objects and things many other tihngs like that. You can still put breakpoints at a specific file line it seems. Also, which kernel are you using? >2.4.9+ or <2.4.5? ptrace sometimes fails for seemingly no reason on 2.4.9, works fine in 2.4.5. But normally all you get is a "cannot attach" or something like that. > i tried use strace and "--debugmsg +all". > HeapAlloc > HeapAlloc > *killed* exit_code=0 > > #./program > #Segmentation fault (core dump) > #gdb program core > #Reading symbols /usr/local/lib/libntdll.so ...... Segmentation fault (core > dump) Hmmm, traces are your friends. Lots of traces. Starting with the application's wrapper. But you will need to put some in the MFC too. Probably starting with dllmodul.cpp (contains DllMain) and appcore.cpp (also invoked during init). -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ Stolen from an Internet user: "f u cn rd ths, u cn gt a gd jb n cmptr prgrmmng !"

can't debug mfc program

by Guilherme Kunz

Hi! I am trying compile a mfc program with winelib. Well, i compiled the part of mfc which i need for use the program whitout erros or unresolved functions and compiled the mfc program with the libmfc.so without errors or unresolved functions, but when i ran the mfc program hapned "Segmentation Fault". I tried use gdb and winedbg but i can't run these debuggers, with gdb happned "Segmentation Fault" with or without breakpoints in the begining of the source and winedbg write only the first line in the window and go out. i tried use strace and "--debugmsg +all". HeapAlloc HeapAlloc *killed* exit_code=0 #./program #Segmentation fault (core dump) #gdb program core #Reading symbols /usr/local/lib/libntdll.so ...... Segmentation fault (core dump) Thank You Guilherme guiok(a)ig.com.br _________________________________________________________ Oi! Você quer um iG-mail gratuito?

cross-process EnableWindow

by Bill Medland

I'm not trying to push; I'd just like to know. Does anyone have an idea how long it will be before EnableWindow can enable a window in another process. Bill
