[Discuss-gnuradio] gr-howto installation issue

[Achilleas Anastasopoulos]

I am building the latest gnuradio source from trunk using "cmake" and
everything is fine.

Then I try to build gr-howto
It seems that this cannot be built with Cmake and that there is a conflict
when i try to build it with make. The error i get is shown below.

If I try to download the latest tarball of gr-howto and build it out
of the gruradio
tree I get the same error.

what is the problem?

thanks
Achilleas
