`make ycm_core` fails – “LONG_BIT definition appears wrong for platform”

[roryokane]

I installed the plugin with Vundle, but when I follow the Mac OS X super-quick installation instructions, I eventually get an error at the step make ycm_core.

$ make ycm_core

I’m on Mac OS X 10.6. I’m using the latest MacVim, Version 7.3 (53). Here’s the top of the output of :version in MacVim:

:version
VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Aug 15 2010 22:03:01)
MacOS X (unix) version

My gcc version is “i686-apple-darwin10-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)”.

Here is the full trace of my installation (with blank lines added between commands). I installed cmake earlier with brew install cmake. In the middle, when the cp failed, that’s because I hadn’t installed the Vim bundle properly; when it worked the second time I ran it, I had run :BundleInstall in MacVim.

If I change the settings from compiling with semantic support for C-family languages to compiling without the support, I still get the error:

[Valloric]

Duplicate issue #6 I think. See that issue for details.

Basically the problem is that cmake is picking up one version of the python dylib and a separate version of python for the headers.

Here's the culprit: -- Found PythonLibs: /usr/lib/libpython2.6.dylib (found suitable version "2.5.1", minimum required is "2.5")

If you want to re-call cmake, don't forget that you need to delete everything in your build directory first, otherwise cmake will re-use the old state.

[Valloric]

Crap I meant issue #18.

[Valloric]

You should probably add the following flags to your cmake call:

 -DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib/libpython2.7.dylib

This will force the paths to the python include dir and the python library to use.

I'm trying to install YCM in cygwin64 on a x86_64 machine and got stuck.

The first error message was

and brought me to this thread.

I've tried to work around with

-DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib/libpython2.7.dylib

but this did not help. (CMake configuration reports the same libs if not provided explicitly anyway.)

Then I've tried to reset the compilers CMake uses: using -DCMAKE_C_COMPILER and -DCMAKE_CXX_COMPILER, I've set the compilers first to /usr/bin/x86_64-pc-cygwin-gcc and /usr/bin/x86_64-pc-cygwin-g++, respectively; then to /usr/bin/i686-pc-cygwin-gcc and /usr/bin/i686-pc-cygwin-g++. But now I get:

Do you have any ideas or experience on how to fix this?

[gitaarik]

@whitedwarfsun I had the same problem, getting the LONG_BIT error in Cygwin. After a lot of searching and trying I came to a solution that worked for me. YouCompleteMe apparently has a Python C++ Boost library included to build it, but somehow that conflicts with the C++ Boost library of the Python installation in Cygwin. What I did was to copy the wrap_python.hpp header file of the Cygwin Python C++ Boost library to the YouCompleteMe Python C++ Boost libary, as in; overwrite it.

In my specific case it was this command, in your case the paths might be different:

cp /usr/include/boost/python/detail/wrap_python.hpp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/BoostParts/boost/python/detail/wrap_python.hpp

Then I ran the ./install.sh script again and it installed successfully, no LONG_BIT error :).

Hope this helps anyone!

[forcemain]

cp /usr/include/boost/python/detail/wrap_python.hpp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/BoostParts/boost/python/detail/wrap_python.hpp

[zuoxinyu]

@gitaarik This solution dosen't work on my cygwin. My python version is 2.7.10 and gcc is 5.2 , the clang is downloaded by the install.py automatically. I try many ways but everything goes wrong. It seems that I have to use a VM for vim.

[vheon]

@zuoxinyu why don't you compile YCM with MSVC?
