MinGW build of 2.6.5: Still having auto-import problems ;-(

[Toralf Lund <toralf procaptura com>]

I'm now trying to build gtkmm 2.6.5 via g++ set up as cross compiler 
with i386-mingw32 output (now that I've got 2.2.12  to work after 
tweaking a bit - I want to support 2.0 *and* 2.4 APIs.) Unfortunately, I 
get the problem described in 
http://bugzilla.gnome.org/show_bug.cgi?id=309030 - despite the fact that 
2.6.5 is supposed to contain a fix for that. It seems like the problem 
is that the GTKMM_API will *not* contain "__declspec(dllimport)" because 
that setup is conditial on GLIBMM_DLL, which won't be defined in my 
glibmm setup (version 2.6.1 built in a similar manner.) The problem is 
the following section of glibmmconfig.h:

// detect common platforms
#if defined(_WIN32)
// Win32 compilers have a lot of varation
#if defined(_MSC_VER)
#define GLIBMM_MSC
#define GLIBMM_WIN32
#define GLIBMM_DLL
#elif defined(__CYGWIN__)
#define GLIBMM_CONFIGURE
#elif defined(__MINGW32__)
#define GLIBMM_WIN32
#define GLIBMM_CONFIGURE
#else

- notice how GLIBMM_DLL won't be defined in the "MinGW" case. I tried to 
rebuild glibmm after inserting

#define GLIBMM_DLL

at the appropriate spot, but then I got

At which point I think all I can do is to cry for help...
