[ik7ytt]

i made new raspberry installation
then installed pihpsdr from internet all ok.
then once i try to use command MAKE i have this request of missing packages:

Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable

Hi Andy,

You can use apt-file to find what package(s) to install:

apt-file search gtk/gtk.h

libgtk-3-dev: /usr/include/gtk-3.0/gtk/gtk.h

so you want to install libgtk-3-dev
