[Discuss-gnuradio] gr-howto-write-a-block build fails

[Tommy Tracy II]

Dear List,

I'm looking to write c++ gnuradio blocks using the gr-howto-write-a-block code that comes with gnuradio.  Unfortunately, when I do the build with the existing code, the tests fail. Has anyone else seen this?

I'm running Ubuntu 12.10.
