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?
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?
std::cout << "Gtkmm " << gtkmm_major_version << "." << gtkmm_minor_version << "." << gtkmm_micro_version << "\n";
g++ `pkg-config --libs --cflags gtkmm-2.4` gtkmm_test.cpp -o gtkmm_test
/tmp/ccZu58l0.o: In function `main':
gtkmm_test.cpp:(.text+0x131): undefined reference to `gtkmm_major_version'
gtkmm_test.cpp:(.text+0x154): undefined reference to `gtkmm_minor_version'
gtkmm_test.cpp:(.text+0x177): undefined reference to `gtkmm_micro_version'
collect2: ld returned 1 exit status
make those all capitals like:
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.
