Issue Details

Hi, when I execute ./install/py --clang-completer, I got trouble. I have searched many sources, but I still cant solve this, I hope to get some help, Thanks!

It said cant find pyconfig.h, I searched it in my environment

# root @ iZ28y724trcZ in ~/.vim/bundle/YouCompleteMe on git:master o [10:14:15] C:1
$ grep -r pyconfig.h *
third_party/ycmd/cpp/BoostParts/boost/python/detail/wrap_python.hpp:    // system headers used by pyconfig.h right here.
third_party/ycmd/cpp/BoostParts/boost/python/detail/wrap_python.hpp:# include <pyconfig.h>
third_party/ycmd/cpp/BoostParts/boost/python/detail/python22_fixed.h:#include "pyconfig.h"
third_party/ycmd/cpp/BoostParts/boost/python/detail/python22_fixed.h:/* pyconfig.h may or may not define DL_IMPORT */

followings are message after I exec ./install.py --clang-complier

Looks like you don't have the Python headers on your machine. On which OS are you?

[DrJian]

Hi, My OS is CentOS 7.0 and my vim is 7.4 and suport python

[micbou]

Could you paste the output of the first 3 lines from the install.py script?

[DrJian]

following is ./install.python first 12 lines

#!/usr/bin/env python

 from __future__ import print_function
 from __future__ import division
 from __future__ import unicode_literals
 from __future__ import absolute_import
 import os
 import subprocess
 import sys
 import os.path as p
import glob

thanks for your anwsering

[micbou]

Sorry, I was not clear. I meant the output from the ./install.py --clang-completer command. It should be something like:

Searching Python 3.5 libraries...
Found Python library: C:\Python35\libs\python35.lib
Found Python headers folder: C:\Python35\include

[DrJian]

sorry ,my falut. They are as follows

./install.py --clang-completer
Searching Python 2.7 libraries...
Found Python library: /usr/lib64/libpython2.7.so.1.0
Found Python headers folder: /usr/include/python2.7
-- The C compiler identification is GNU 4.8.2
-- The CXX compiler identification is GNU 4.8.2
-- Check for working C compiler: /usr/bin/cc

[micbou]

I am not a CentOS expert but your issue should be fixed by installing the python-devel package:

yum install python-devel

and running again the ./install.py script.

[DrJian]

thank u a lot. Now the trouble missed. and it's compiling now

[micbou]

Great. I am closing the issue then.

[aminroosta]

Ubuntu version:

apt-get install python-dev

[npujcong]

I check the install.sh 12 PYTHON_BINARY=python
13 if command_exists python2; then
14 PYTHON_BINARY=python2
15 echo "python2"
16 fi
and i find there exist Python2 and Python3 meanwhile。And it would execute python2. So I change python2 to python3 and if fixed.
13 if command_exists python2; then
14 PYTHON_BINARY=python2
15 echo "python3"
16 fi

[bstaletic]

You should be using install.py, not install.sh.
