I tried to implement python OOT module as given in the new tutorial. Everything was fine till I reached the installation step. cmake command made the following error..
-- Build type not specified: defaulting to release.
You have called ADD_LIBRARY for library gnuradio-qpsk_demod without any source files. This typically indicates a problem with your CMakeLists.txt file
CMake Error: CMake can not determine linker language for target:gnuradio-qpsk_demod
Going through mailing list I found that this can be overcome by removing the lib subdirectory from the CMakeLists.txt file. I removed that file and run cmake .. It ran fine. Then make command was given,.. the following was the result
