Non gcc/linux64 portability issues

[ronawho]

Looks like the backend compiler is always given -static and --whole-archive options. The former is not supported on OSX, and the latter is a gcc flag. Other compilers might support it (I didn't check pgi, intel, or cray) but I'm pretty sure clang doesn't

[awallace-cray]

Confirmed, pychapel + clang on OS-X will not work.
Gcc link commands (and other things) are largely hard-coded in pychapel/module/configs/pych.json, will only work with linux64, gcc, system-installed python 2.7.

Chapel itself includes a nice build system which supports compilation and linking of all things "Chapel", in many environments. Pychapel should take advantage of that. For example, instead of using the hard-coded gcc command line template in pychapel/module/configs/pych.json, perhaps Pychapel could "ask" chpl (or a new target in Chapel's Make system, or a new chplenv Python utility) for the appropriate link command for the current environment.

@ben-albrecht and I experimented with just sending the clang equivalent of --whole-archive instead and were able to get tests to run successfully. We have an action item for one of us to add the detection necessary to work in both situations

[ben-albrecht]

That flag is -all_load for clang. We also removed --no-whole-archive.

For completeness, here's the patch that will get OSX working for PyChapel:

Thinking about creating/building a Pychapel Homebrew formula using a temporarily-patched Pychapel source tree. Even if the patch is not on master branch yet.

Unable to get all pychapel unit tests to work on my Macbook.

• avoided some errors by rm'ing -fopenmp from gcc commandline template
• test cases using matplotlib are still broken

FWIW, @lydia-duncan and I did not run the full test suite with these changes.

This SO post might be helpful for matplotlib setup (assuming it's not PyChapel-specific)

[awallace-cray]

That backend change gets the tests to run- good! I wonder if a user app could actually make a plot. I'm not going to stop and check.

Created a set of rudimentary build scripts for Pychapel on Mac OS X.

https://gist.github.com/awallace-cray/31da7c2f2333e56cb7949f94d5fcea5f no longer works.
See issue #75
2018-04-03 : It was fixed and re-tested 01/23. https://gist.github.com/awallace-cray/31da7c2f2333e56cb7949f94d5fcea5f#gistcomment-2331061. Sorry, I missed noting that here.

It looks like https://gist.github.com/awallace-cray/31da7c2f2333e56cb7949f94d5fcea5f#file-pychpl-2-full-pych-sh was run without preparing the machine as described in https://gist.github.com/awallace-cray/31da7c2f2333e56cb7949f94d5fcea5f#file-pychpl-0-readme-txt. At least, the virtualenv tools do need to be installed.

[buddha314]

It was installed, but I re-installed the wrapper and setup tools:
