Hi,

Does anyone have experience in using Sybase DB-Library with gcc/g++?

I have managed to link against libsybdb by creating .a from .LIB using
impdef and dlltool as explained in this mailing list.  However, the
application crashes inside dbopen() where I can't step into.  I have
spend hours and still have no idea how to fix the problem...

I used "example1.c" in Sybase dblibrary example directory.  Calls to
dbinit(), dberrhandle(), and dbmsghandle() are successful up until it
crashes in dbopen().  As you see in the output below, a connection to
the server seemed to have established before the crash.

Has anyone seen this before?  Any information will be helpful.
