A while back I posted a question about how to get debugging working with eclipse in fedora 4. I am having some success, so if anyone else out there is interested here's how it is set up. In regedit: * disabled auto winedbg by renaming AeDebug I changed HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/AeDebug to AeDebug-DISABLED. Without this gdb doesn't seem to be able to get a hold of SEGFAULTs. In eclipse's Run/Debug dialog box: * set the c/c++ application to WINE_SRC/loader/wine-pthread WINE_SRC points to a compiled version of wine. For me, I got the wine src rpm and ran rpmbuild -bb. This is where main() is, which eclipse looks for at start up. * put your .exe.so file on the Arguments tab * choose the GDB Debugger on the Debugger tab * add WINE_SRC on the Source tab as a "Filesystem directory with subdirectories" The only weirdness so far is that sometimes (not always) the debugger suspends when a new thread is created. I just resume (F8) past that. And I am not sure what impact bypassing wine-preload's exec-shield workaround will have on me. More on that if I learn more. But I gotta say that having a functioning IDE with integrated debugging on Linux is a major relief and, for me at least, a long time coming! ... mo PS: I installed FC4, and then did yum update. eclipse is version 3.1.1 updated from the eclipse UI from the version that came with FC4.
