Bug 131219 – gtkmm-2.8.1 library is missing three important constants

• Status: VERIFIED INVALID
• Product: Gentoo Linux

[Description Alex Buell 2006-04-25 06:24:18 UTC]

Much like glib and gtk, gtkmm also has three constants; gtkmm_major_version, gtkmm_minor_version and gtkmm_micro_version. But when I try using these constants in my code, I get linkage errors.

gtk-2.8.1 is not in portage... what ebuild is this exactly about?

[Comment 2 Alex Buell 2006-04-25 06:59:59 UTC]

Just amended gtk-2.8.1 to gtkmm-2.8.1, sorry about that!!

Reopened with amended summary line.

can you attach example source + how you are attemping to compile/link it?

#include <gtkmm.h>
#include <iostream>

int main()
{
        std::cout << "Gtkmm " << gtkmm_major_version << "." << gtkmm_minor_version << "." << gtkmm_micro_version << "\n";
        return 0;
}

g++ `pkg-config --libs --cflags gtkmm-2.4` gtkmm_test.cpp -o gtkmm_test
/tmp/ccZu58l0.o: In function `main':

make those all capitals like:

GTKMM_MAJOR_VERSION
GTKMM_MINOR_VERSION
GTKMM_MICRO_VERSION

and you won't have those errors.

How strange - they're certainly lower case in /usr/include/gtkmm-2.4/gtkmm!
But thank you, that's solved my problem.
