Re: problem in gtk programming

["dark0s Optik" <shiftcoder@xxxxxxxxx>]

I installed pkg-config, xproto, renderproto and kbproto packages
because they required.
Now if I type:

#gcc 'pkg-config gtk+-2.0 --libs --cflags' prova.c -o prova
gcc: pkg-config gtk+-2.0 --libs --cflags: No such file or directory

If I type:

#gcc '/usr/pkg/bin/pkg-config gtk+-2.0 --libs --cflags' prova.c -o prova
gcc: /usr/pkg/bin/pkg-config gtk+-2.0 --libs --cflags: No such file or directory

How can I include pkg-config in gcc command?

savio
