[Discuss-gnuradio] CMake build problem

[matt . nottingham]

Hi,

I'm running debian unstable on a AMD64 platform and am running into a
problem which starts right at the top of the build process for a newly
checkout gnuradio version from git.

Below is output from running cmake:

[snip]
-- Performing Test HAVE_WARN_ALL
-- Performing Test HAVE_WARN_ALL - Success
-- Performing Test HAVE_WARN_NO_UNINITIALIZED
-- Performing Test HAVE_WARN_NO_UNINITIALIZED - Success
-- Found PythonLibs: 
optimized;/usr/lib/python3.2/config/libpython3.2.so;debug;/usr/lib/python3.2/config/libpython3.2.so
 (found version "2.7.3rc2")
-- Found SWIG: /usr/bin/swig2.0 (found version "2.0.4")
[snip]

So it found that /usr/bin/python is version 2.7.3rc2, but it decides
to use version 3.2 to link against. This makes the build process
rather sad later on! (Lots of link failures)

To get around this I changed in CMakeLists.txt

   find_package(PythonLibs)

to be

   find_package(PythonLibs 2.7.3)

But obviously that'll only work for people running 2.7.3! (I've not
played with cmake before now, so there might be a simple way to fix
it) 

I'm running cmake version 2.8.7.

However the build process goes further this time, but now breaks with:

Which I don't know where to start to fix! However I can tell you that
the file its looking for, /home/...../swig/gengen_swig_doc.i doesn't
exist, but I don't know what should have created it.


Thanks,

Matt
