Hello, I'm trying to get a program in the programs/ directory to export symbols, I've added -shared path/to/spec/spec.c to the linker command, but I now get a segmentation fault at startup. Can someone knowledgeable about winegcc/winebuild give me a suggestion/solution? I'm really stuck because of this and can't get on with safedisc support.
Ivan.

Why not provide an strace/ltrace trace of that SEGV?

Definitely not me. ;-)

Doh! Hopefully my suggestion will provide more clues.

ltrace fails with this $ltrace /usr/local/bin/wine ntoskrnl ltrace: dict.c:117: dict_apply_to_all: Assertion `d' failed. Aborted strace output is attached (It's bziped because it was over 200k uncompressed).

Well, I ran winegcc manually with the -v option, and found that normally programs build something with spec in the name anyway, so I changed the extension of my spec to .sspec and got the attached ntoskrnl.sspec.c file, unfortunately the build fails with make: Circular ntoskrnl.sspec.c <- ntoskrnl.sspec dependency dropped. make: Nothing to be done for `all'. so without changing the makefile I renamed the file to .spec again and got this

the program has a WinMain() and not a main(), all the exported functions are in the source, so I'm not sure about the reason for these errors. What I now think is that programs probably have some default spec that's built on the fly for them, and this is interfering with my spec. This is a real shame because ntoskrnl can actually run safedisc ATM, but it crashes when Secdrv.sys can't call the ntoskrnl functions it imports. The file I did build with a .spec file and that segfaults is at http://spazioinwind.libero.it/nonsolomicrosoft/public/spec/ntoskrnl.exe.so
