Re: Compiling with Eclipse

[Rodrigo Nunes <rnsribeiro gmail com>]

Forgive my ignorance, but how do I change this in eclipse?

I've tried everything here and I can not solve.

Change
g++ `pkg-config gtkmm-3.0  --libs --cflags` -o "gtkmmdemo"  ./src/gtkmmdemo.o
to
g++ -o "gtkmmdemo"  ./src/gtkmmdemo.o `pkg-config gtkmm-3.0  --libs --cflags`

From the description of gcc, option -l (lowercase l):

It makes a difference where in the command you write this option; the linker
searches and processes libraries and object files in the order they are speci-
fied. Thus, ‘foo.o -lz bar.o’ searches library ‘z’ after file ‘foo.o’ but before
‘bar.o’. If ‘bar.o’ refers to functions in ‘z’, those functions may not be loaded.

I'm trying to compile a simple program, has set up the eclipse as in this tutorial:

http://kapo-cpp.blogspot.com.br/2008/01/using-eclipse-for-your-gtkmm-project.html

I'm using gtkmm-3.0.

gtkmmdemo.cc

------------------------------------------

#include <gtkmm.h>

int main(int argc, char *argv[])

{

Gtk::Main kit(argc, argv);

Gtk::Window window;

Gtk::Main::run(window);

return 0;

}

And the error message I get is this:
