YouCompleteMe Installation Problems

I am trying to install YouCompleteMe on my university server which runs Debian Linux(in my user home). When I run:

./install.sh

I get the following error after the "Building CXX object" stage.

[ 98%] Building CXX object ycm/CMakeFiles/ycm_core.dir/ycm_core.cpp.o

The error message says "recomile using -fPIC" what must I recompile? Thank you.

I just resolved this issue; same as yours: I have my own Python installed. I referenced this solution, yet I did it in a little bit different way.

  1. First check if you have libpython2.7.so in your own lib dir (in your case it's ~/lib/). If there's only libpython2.7.a, you may need to recompile python for the shared library. Look to this for reference. In short you should go to your python source code, and:

    ./configure --enable-shared \
            --prefix=$HOME \
            LDFLAGS="-Wl,--rpath=$HOME/lib
make
make install

  2. You could run into trouble if your system has a Python itself. The issue looks like:

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libpython2.7.a: could not read symbols: Bad value

In this case, please refer to this solution and go back to step 1.

Otherwise, just go ahead.

  1. Now I assume you have libpython2.7.so in your lib dir. Change ~/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py a little bit:

    • Modify the function CustomPythonCmakeArgs(), replacing

      python_library = '{0}.a'.format( lib_python )

      with

      python_library = '{0}.so'.format( lib_python )

    • Add a line nearby

      python_executable = '{0}/bin/python'.format( python_prefix )

    Your python interpreter may be in some other location, change it accordingly.

    • Change the return value from 

      return [
    '-DPYTHON_LIBRARY={0}'.format( python_library ),
    '-DPYTHON_INCLUDE_DIR={0}'.format( python_include ),
]

      to

      return [
    '-DPYTHON_LIBRARY={0}'.format( python_library ),
    '-DPYTHON_INCLUDE_DIR={0}'.format( python_include ),
    '-DPYTHON_EXECUTABLE={0}'.format( python_executable ), 
]

    • Also remember to comment out

      if OnMac():
    full_cmake_args.extend( CustomPythonCmakeArgs() )

      like this

      # if OnMac():
full_cmake_args.extend( CustomPythonCmakeArgs() )

You should be good after doing these. Go back to ~/.vim/bundle/YouCompleteMe and install again

./install.py --clang-completer
