[Linphone-developers] Compilation Error

[voip coders]

I am getting following error while compiling linphone, can someone help

checking for LIBGTK... configure: error: in `/home/eric/linphone/linphone-3.2.0':
configure: error: The pkg-config script could not be found or is too old.  Make sure it

is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.


Thanks
Eric
