kiwisolver build fails on TravisCI

[brett-patterson]

The TravisCI build fails when trying to install kiwisolver with the following error:

The package setup script has attempted to modify files on your system

that are not within the EasyInstall build area, and has been aborted.

This package cannot be safely installed by EasyInstall, and may not

support alternate installation locations even if you run its setup

script by hand. Please inform the package's author and the EasyInstall

maintainers to find out if a fix or workaround is available.

The command "python setup.py develop" failed and exited with 1 during .

Your build has been stopped.

Any ideas why it's trying to access /tmp/ or how to fix?

You can't easy-install kiwi without running the build.py script first. This is because python's manifest file has concept of relative ancestor directories. This means that all of the C++ headers have to be copied into the Python directory first.

The easiest way to build kiwi is to run:

python build.py [build|develop|install]

which will copy the right files and then invoke setup.py

I'm open to suggestions/improvements on the setup script.

This is working for me (with setup.py in the repo root):

ext_modules = [
    Extension(
        'kiwisolver',
        ['py/kiwisolver.cpp',
         'py/constraint.cpp',
         'py/expression.cpp',
         'py/solver.cpp',
         'py/strength.cpp',
         'py/term.cpp',
         'py/variable.cpp'],
        include_dirs=['.', 'kiwi', 'py'],
        language='c++',
    ),
]

And the MANIFEST.in looks like this:

include MANIFEST.in
include COPYING.txt
include README.rst
include releasenotes.rst
recursive-include kiwi *.h
recursive-include py *.cpp *.h
