My system: CentOS 6.2, x86_64 Python 2.6.6 Cmake version 2.6-patch 4 gnuradio 3.7.0
I created a "build" folder in the gnuradio soure directory and attempted to compile using "cmake ../". The error I keep getting is this: --------------------------------------------START LOG------------------------------------------------------------- -- Build type not specified: defaulting to release. -- NO PERF COUNTERS -- Minimum SWIG version required is 1.3.31 -- -- The build system will automatically enable all components. -- Use -DENABLE_DEFAULT=OFF to disable components by default. -- -- Configuring python-support support... -- Dependency PYTHONLIBS_FOUND = TRUE -- Dependency SWIG_FOUND = 1 -- Dependency SWIG_VERSION_CHECK = TRUE -- Enabling python-support support. -- Override with -DENABLE_PYTHON=ON/OFF -- -- Configuring testing-support support... -- Dependency CPPUNIT_FOUND = TRUE -- Enabling testing-support support. -- Override with -DENABLE_TESTING=ON/OFF -- -- Configuring volk support... -- Enabling volk support. -- Override with -DENABLE_VOLK=ON/OFF File "<string>", line 1 ^ SyntaxError: invalid syntax CMake Error at volk/cmake/GrPython.cmake:105 (file): file FILE(SYSTEM_PATH ENV result) must be called with only three arguments.

I found that I was able to resolve the problem by editing volk/cmake/GrPython.cmake to put all the python code on one line as follows: ----------------------ORIGINAL CODE---------------------------------- ######################################################################## # Sets the python installation directory GR_PYTHON_DIR ######################################################################## execute_process(COMMAND ${PYTHON_EXECUTABLE} -c " from distutils import sysconfig print sysconfig.get_python_lib(plat_specific=True, prefix='') " OUTPUT_VARIABLE GR_PYTHON_DIR OUTPUT_STRIP_TRAILING_WHITESPACE ) file(TO_CMAKE_PATH ${GR_PYTHON_DIR} GR_PYTHON_DIR) ----------------------------EDITED CODE---------------------------------- ######################################################################## # Sets the python installation directory GR_PYTHON_DIR ######################################################################## execute_process(COMMAND ${PYTHON_EXECUTABLE} -c "from distutils import sysconfig; print sysconfig.get_python_lib(plat_specific=True, prefix='');" OUTPUT_VARIABLE GR_PYTHON_DIR OUTPUT_STRIP_TRAILING_WHITESPACE ) file(TO_CMAKE_PATH ${GR_PYTHON_DIR} GR_PYTHON_DIR) --------------------------END CODE----------------------------------------------- Note that trying to put "from distutils import sysconfig" on the same line as the open quotemark does not resolve the problem either (it also seems to append a CR to the end of the line and python barks at me). However, this process is very tedious, and it seems like there should be a better way of fixing it, and it does not work for the sections of python code in the cmake files where there are if/else blocks. Is there a better way of resolving this problem, or has anyone else had this problem? _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
