I'm trying to install avidemux when i do ./configure i get an error saying that i'm missing gtk 2.0. I'm using knoppix. I would think that that's already installed. I am rather new to linux. The error message says to add to the PKG_CONFIG_PATH environment variable... can anyone tell me how to do this?
here's the last part of the output from ./config ...
checking for msgmerge... /usr/bin/msgmerge
checking for ld used by GCC... /usr/bin/ld
checking if the linker (/usr/bin/ld) is GNU ld... yes
checking for shared library run path origin... done
checking whether NLS is requested... yes
checking for GNU gettext in libc... yes
checking whether to use NLS... yes
checking where the gettext function comes from... libc
checking for pkg-config... /usr/bin/pkg-config
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
