Oh how I wish that was the fix, but sadly, no it's not. My EPEL was enabled by default. I went so far as to enable EPEL-testing, but no change.

Hi Richard,
I've gotten rid of my CentOS 6.5 VM in favor of CentOS 7, where this was not an issue.
However, usually "broken links" should not happen in CentOS.
Did you "yum clean all", "yum check-updates" before installation? That should make absolutely sure only the newest packet lists from the official servers are used.
As a general reference for CentOS users: It often seems very helpful to use the EPEL archives [1], which basically adds most of the packages that are missing in RHEL, CentOS and Scientific Linux compared to Fedora.

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 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:
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.
