Hey
all!
After some hard
work, i've released another version of wgcc (see sourceforge, "interix-wgcc")
which now has some major improvements for shared libraries (and static ones, and
mixing both types of libraries), it even generates some assembler code on the
fly while linking..... ;o)
Now i'd need some
people who have some spare time to take a look at wgcc and test it a little. I
so far got nearly no feedback on things working or not, so i can only tell that
the things i compile myself work... Would be great to know a little
more.
If you are
interested, just read on the few following lines, i'll explain some
traps:
for global variables
in shared libraries one has to modify the sources a little. If you have the
following original sources:
==================
lib.h:
extern int
variable;
lib.c:
#include
"lib.h"
int variable =
10;
==================
you will have to
modify that to look something like that to work on all
platforms:
==================
lib.h:
#if
defined(_WIN32)
#
if defined(_COMPILING_lib_)
# define _lib_EXPORT
__declspec(dllexport)
#
else
# define _lib_EXPORT
__declspec(dllimport)
#
endif
#else
#
define _lib_EXPORT
#endif
extern _lib_EXPORT
int variable;
lib.c:
#include
"lib.h"
_lib_EXPORT int
variable = 10;
==================
just define _COMPILING_lib_ if you're
compiling the shared library objects, and DON'T worry about static libraries, if
you need them, they will work with exactly the same sources as shown above,
since wgcc generates some assembler sources to include all symbols needed for
this, and somehow fits things together (i not quite sure if _I_ know how it
works ;o))
this should be everything you have to know
to test things. I just added the import/export defines above myself to
i-don't-know-how-many files, and my fingers still hurt ;o) but it's worth... and
it doesn't take too long... ;o)
i hope somebody has interest in this,
otherwise tell me !
Regards,
Markus
