Re: gmodule help

["Greg Steffensen" <greg steffensen gmail com>]

Thanks- its actually quite simple.  In case anyone else searches for info on this, on Linux, shared libraries usable with gmodule are compiled via

gcc -shared -fPIC -o libmylib.so libmylib.c `pkg-config --cflags --libs 
glib-2.0`

The pkg-config arguments may need to be tweaked depending on your project, of course (if you're using, say, the G_MODULE_EXPORT macro inside your module, you'll need to add "gmodule-2.0" to your pkg-config args, for example... but that macro is only necessary for cross platform compatibility, its not needed if your code is intended only for Linux).

It is probably overkill, but you can take a gander at the Makefile.am
Makefile.in configure and configure.ac in:

http://www.netperf.org/svn/netperf4/branches/glib_migration

for examples of what may not be pristine, nor adhere to chapter and
verse, but seem to be functional use of libtool with automake et al and
GModule.

One thing I've just learned getting netperf4 to work on Linux, HP-UX,
AIX, MacOS X and Windows is that "g_module_open means never having to
include the suffix" so you can, and perhaps should (?) drop the ".so"
