Re: [Discuss-gnuradio] GRC Command Not Found

Thanks for that Martin. I enjoy learning things like this. What it shows is gnuradio-companion is disabled because it does not recognize pygtk installed.

For whatever reason, the package-manager system on my centos 6.6 machine has a broken link for pygobject and pygtk. I can't depend on yum or pybombs to install it for me.

I've downloaded pygobject from here: http://ftp.gnome.org/pub/GNOME/sources/pygobject/2.27/

I've downloaded pygtk from here: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.17/

I've been struggling for hours trying to get pygobject installed correctly so that pygtk recognizes it as being installed. Extracting pygobject to pybombs/src/pygobject I run ./configure, make, sudo make install. No errors arise and I see a new file create in my /usr/local/bin

When I then extract pygtk to pybombs/src/pygtk and run ./configure, I receive the following partial output:

checking for GLIB - version >= 2.8.0... yes (version 2.28.8)
checking for PYGOBJECT... configure: error: Package requirements (pygobject-2.0 >= 2.16.1) were not met:

No package 'pygobject-2.0' found

My path variable includes all the standard locations and I did not change the default install location of pygobject.

I'm at my wits end with this. Help would be greatly appreciated.

P.S. Is it possible to fix this error with a yum repo hack?

The ftp link it's using is correct, but for a filename error:

This: http://gensho.acc.umu.se/pub/GNOME/sources/pygobject/2.27/pygobject-2.27.91.patched.tar.gz

Should be http://gensho.acc.umu.se/pub/GNOME/sources/pygobject/2.27/pygobject-2.27.91.tar.gz

Removed patched from the tarball filename. I don't know how pybombs determines that link.

Was GRC even built? Run "cmake .." from the GNU Radio build directory
(usually something like pybombs/src/gnuradio/build) and see if it's
among the enabled components.
