Slackware- GTK 3 with GTKMM 3 and cairo

Hi!

I have done some tutorial with not problem with gtkmm 2.4

But today I am trying to do the tutorial here

I have created the 3 files as their give code here:

I have in the systems:
glibmm-2.32.1-i486-1_SBo
gtkmm-2.24.2-i486-1_SBo
gtkmm-utils-0.4.1-i486-1_SBo
gtkmm3-3.4.1-i486-1_SBo

I compile it by typing:

g++ -Wall -o GTK_test main.cc `pkg-config --cflags gtkmm-3.0 --libs gtkmm-3.0`

I get:

Code:

/tmp/ccOapu9M.o: In function `main':
main.cc:(.text+0xa4): undefined reference to `MyArea::MyArea()'
main.cc:(.text+0xe8): undefined reference to `MyArea::~MyArea()'
main.cc:(.text+0x140): undefined reference to `MyArea::~MyArea()'
collect2: error: ld returned 1 exit status
make: *** [test] Error 1

What is it wrong?

You would need to list all the source files on the command line.

e.g.

Code:

g++ -Wall -o GTK_test main.cc myarea.cc `pkg-config --cflags gtkmm-3.0 --libs gtkmm-3.0`

Thanks Speccy! This works!

Why gcc would not work? it gives this error:

Code:

/usr/lib/gcc/i486-slackware-linux/4.7.1/../../../../i486-slackware-linux/bin/ld: /tmp/ccz7YdYR.o: undefined reference to symbol '_ZdlPv@@GLIBCXX_3.4'
/usr/lib/gcc/i486-slackware-linux/4.7.1/../../../../i486-slackware-linux/bin/ld: note: '_ZdlPv@@GLIBCXX_3.4' is defined in DSO /usr/lib/libstdc++.so.6 so try adding it to the linker command line
/usr/lib/libstdc++.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make: *** [test] Error 1

Because gcc compiles/links C-Files. And your .cc files are C++...

Good luck!
