Re: [Discuss-gnuradio] OOT Module Template Expansion Issues

[Jacob Gilbert]

Thanks Martin,

I added something like this to the CMakeLists.txt files in lib and include/testmod:

file(WRITE ${CMAKE_CURRENT_BINARY_DIR}/generate_helper.py

"#!${PYTHON_EXECUTABLE}

import sys, os, re

sys.path.append('${GR_RUNTIME_PYTHONPATH}')

sys.path.append('${CMAKE_CURRENT_SOURCE_DIR}/../python')

os.environ['srcdir'] = '${CMAKE_CURRENT_SOURCE_DIR}'

os.chdir('${CMAKE_CURRENT_BINARY_DIR}')

if __name__ == '__main__':

  import build_utils

  root, inp = sys.argv[1:3]

  for sig in sys.argv[3:]:

      name = re.sub ('X+', sig, root)

      d = build_utils.standard_impl_dict2(name, sig, '${component}')

      build_utils.expand_template(d, inp)

")

Is that what you mean? Or can I tell CMake to use the module in tesmod/cmake/Modules/GrPlatform.cmake?

I'd like to know the recommended way, and we can get this added into the modtool templates.

The short answer is, the templated in-tree stuff has access to some
modules we don't actually export to OOTs. You'll need to copy the
template infrastructure into your OOT.

Cheers,
Martin
