OS X building?

[mrak]

I've installed boost and cmake through homebrew and ./install.sh seems to go through without a hitch.

$ ./install.sh
-- Boost version: 1.58.0
-- Found the following Boost libraries:
--   program_options
-- Configuring done
CMake Warning (dev):
  Policy CMP0042 is not set: MACOSX_RPATH is enabled by default.  Run "cmake
  --help-policy CMP0042" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  MACOSX_RPATH is not specified for the following targets:

   cpsm_py

This warning is for project developers.  Use -Wno-dev to suppress it.

When I load up vim and try to use CtrlP, vim crashes with the following:

Vim: Caught deadly signal ABRT
Vim: Finished.

I get the same problem:

(fr5.1)~/.vim/bundle/cpsm (master) :) Fatal Python error: PyThreadState_Get: no current thread
Vim: Caught deadly signal ABRT
Vim: Finished.

Same here!

Do you all have Python (2 or 3) installed through Homebrew? Some Googling around seems to indicate that there is an upstream CMake problem where CMake incorrectly selects Mac OS X's Python libraries over other Python libraries (Homebrew is the usual culprit); http://www.itk.org/Bug/view.php?id=14809 is the CMake tracking bug, and Homebrew/legacy-homebrew#25118 is a Homebrew bug with some discussion.

I've committed 01e2392 to master to fix this. However, even without that commit I haven't been able to reproduce a crash, even after brew install python and brew install python3. Can you please try and let me know?

[gonzaloserrano]

Hi,

Still crashes, i removed the build directory and compiled again after pulling last version. The build process output is here: https://gist.github.com/gonzaloserrano/11b4f25ac5057748526d

As you can see i'm using python 2.7.9 from homebrew.

[svenstaro]

I'm not sure this big external Find.cmake module is required. After all, YouCompleteMe also only uses the systemlibs. The commit broke systems that use Python 3 as a default system lib.

[svenstaro]

Looking at FindPythonLibrary.cmake now, I don't think you're really fixing any problems by using it because it uses FindPythonInterp which is supplied by CMake and will still find the wrong versions of Python on a badly configured OSX.

[nixprime]

gonzaloserrano, can you provide the output of otool -L $(which vim) and otool -L ~/.vim/bundle/cpsm/autoload/cpsm_py.so?

svenstaro, according to the CMake bug report, FindPythonInterp may find a different Python than FindPythonLibs since it honors PATH.

[gonzaloserrano]

Yep looks like cpsm uses the system python and homebrewed vim the corresponding homebrew python one: https://gist.github.com/gonzaloserrano/f1a70e42069c8815b875

[nixprime]

Can you run which python and brew doctor? Probably /usr/bin is before /usr/local/bin in your path, causing the system Python interpreter to be selected over the Homebrew Python interpreter, which is now what's used to select the Python libraries used to build cpsm.

[gonzaloserrano]

AFAIK in my env /usr/local/bin has precedence over /usr/bin in $PATH:

╰─○ type -a python
python is /usr/local/bin/python
python is /usr/bin/python

brew doctordoesn't show anything related to python.

I'll try to dig further tomorrow. Thanks four your help!

Did you come upon a solution here @gonzaloserrano? I'm having the same issue.

[gonzaloserrano]

Not yet, this week has been so busy. Sorry! :-(

[glortho]

This appears to be a solution to the same/related problem: ycm-core/YouCompleteMe#8

[gonzaloserrano]

I tried this: $ EXTRA_CMAKE_ARGS='-DPYTHON_EXECUTABLE=/usr/local/bin/python' bash install.sh without luck. What did you end up doing to make it work?

[glortho]

Well, I actually haven't solved it entirely, though it of course works by flattening namespace:

DYLD_FORCE_FLAT_NAMESPACE=1 vim

[nixprime]

jedverity, can you provide the output of the following:

• otool -L $(which vim)
• otool -L ~/.vim/bundle/cpsm/autoload/cpsm_py.so
• which python
• brew doctor

[glortho]

I do have the problem of cpsm using System python
(/System/Library/Frameworks/Python.framework/Versions/2.7) and vim using
homebrew python
(/usr/local/Cellar/python/2.7.10/Frameworks/Python.framework/Versions/2.7,
which is also first on PATH).

Anyone on OSX with home brew python gotten this working?

In OS X, In some cases it will be linked to the system Python (/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython.dylib) with -framework Python flag.

but, If installed Python and vim use Homebrew, .dylib (in Linux .so) path is /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib.

In the current state,
e.g.

• PYTHON_EXECUTABLE=/usr/local/bin/python
• PYTHON_INCLUDE_PATH=/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/include/python2.7
• PYTHON_LIBRARY=/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython.dylib

Since the {exe | include} and lib is different python, an error will occur.

Simple hack solution is -framework Python to /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib
https://github.com/nixprime/cpsm/blob/master/cmake/FindPythonLibrary.cmake#L88
but, It's likely to be a little more concise.

I do not know how to write CMakefile, I can not post the PR. Sorry.

- set (PYTHON_LIBRARY "-framework Python" CACHE FILEPATH "Python Framework" FORCE)
+ set (PYTHON_LIBRARY "/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib" CACHE FILEPATH "Python Framework" FORCE)
