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

It seems as if cmake is inserting a "CR" character at the beginning of each
string that is passed to python.
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?
