Got an error while building with CMake -Python2.7.a: error adding symbols

Hi,

First of all, thank you for developing this kind of application to improve our productivity. I am new to Linux environment and new to vim as well.

I am trying to use YCM but i cannot build it at the moment. I got an error at 90% while building with CMake. The error was:

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32S against '_Py_NotImplementedStruct' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libpython2.7.a: error adding symbols: Bad value collect2: error: ld returned 1 exit status make[3]: *** [/home/ibrahim/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_core.so] Error 1 make[2]: *** [ycm/CMakeFiles/ycm_core.dir/all] Error 2 make[1]: *** [ycm/CMakeFiles/ycm_support_libs.dir/rule] Error 2 make: *** [ycm_support_libs] Error 2 `

Eventually i built YCM, after that i get some error from vim

See issue #1639. Your python is certainly not built with the --enable-shared (first error) and --enable-unicode=ucs4 (second error) flags. I am closing this since it is a configuration issue.

Well, finally solved this issue.

I will explain my experience briefly.

I had to reinstall Ubuntu 14.04 because I messed up python libraries. You need to rebuild python. In order to do that I strongly recommend to replace pre-installed python with your new one. I did not want to take any risk so I build python 2.7.6 with --enable-shared and --enable-unicode=ucs4 configurations. Keep in mind that before you configure python you should install some dependencies:

sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

You NEED gocode. -in my case I was trying to use YCM for go-lang auto completion and I missed this point form the installation guide- Here you can find installation instruction for gocode:

https://github.com/nsf/gocode

after these you can easily build and use.

For Pathogen users like me

0- make sure your Vim has python support. To see that :echo has('python') if not, pre-built vim has python and you can get it by sudo apt-get install vim
1- git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/
2- cd ~/.vim/bundle/YouCompleteMe/ and then git submodule update --init --recursive
3- make sure you have right built python I explained above.
4- make sure you have cmake if you dont have: sudo apt-get install cmake
5- cd ~/.vim/bundle/YouCompleteMe/ and then ./install.py --gocode-completer
6- use.

Sorry for mess, as I mentioned before I am new to Linux environment. Now YCM works without any issues.
