Re: [Mingw-cross-env-list] Static library support for GTK+

[Matthias Gehre]

As mentioned in another thread,
I'm currently building lightspark with option (C)  (one big DLL),
but I needed to apply some fixes, which should make option (A) work, too.

The problem is, that glib,gtk's and so on DllMain gets not called,
which is needed to setup a few things. Usually it sets a HINSTANCE
variable, so that
one can find the installation directory with that.
Glib's DllMain does even more things like
setting up some thread related stuff (I haven't looked up all of those
functions called from DlllMain).

Without that, glib_spawn will fail, for example, because it cannot
find the gspawn-helper.exe application.

I cannot see another difference between static and dynamic library
than not calling DllMain.

My approch was to export all those DllMain's as, say, glib_DllMain,
and then call them from within my 'big' Dll's
DllMain.

For option (A), the setting of a hinstance variable can of course
fixed somehow. (Actually, using hinstance=NULL gives
the path of the current executable, which would be just right. Then
one only has to make sure that the executable exports
all symbols required by dlopen' like procedures)
But DllMain is also called on thread attach/detach, which can be hard
to emulate by other means.

Best wishes,
Matthias
