Re: problem building gr-howto-write-a-block-cmake

Apologies for resurecting this thread, but i still have not resolved
this issue.
I have an otherwise perfectly working latest gnuradio-trunk but have
not been able
to build gr-howtowriteablock-cmake package.

Is there any way I can trace why cmake cannot find PythonLibs?

thanks for the help,
Achilleas

Yea this is totally strange that it finds python libs in the regular
build and not here. Perhaps there is some variable set prior to finding
python libs in the howto thats not set in the main build.

I might suggest that you start deleting things until it works. For
example, start deleting subdir includes (except swig) until it works:

add_subdirectory(include)
add_subdirectory(lib)
add_subdirectory(swig)
add_subdirectory(python)
add_subdirectory(grc)
add_subdirectory(apps)
add_subdirectory(docs)

or move around the call to find_package(PythonLibs) higher up in the top
level Cmakelists until it works.

Achilleas,

Can you also send your output from running cmake in an empty build
directory for GNU Radio so we can compare those results with these from
the
howto directory?

Thanks,
Tom
