MacVim , vim: Python support does not work

[wichert@…]

I noticed that for both binary and source installs of MacVim the python variant does not work. When trying to compile with +python27 I see the following in the debug output:

checking Python version... 2.7
checking Python is 1.4 or better... yep
checking Python's install prefix... /opt/local/Library/Frameworks/Python.framework/Versions/2.7
checking Python's execution prefix... /opt/local/Library/Frameworks/Python.framework/Versions/2.7
checking Python's configuration directory... /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config
checking if -pthread should be used... no
checking if compile and link flags for Python are sane... no: PYTHON DISABLED

The exact same problem occurs with the vim port as well.

Looking at config.log shows why it fails:

configure:5285: checking Python's install prefix
configure:5294: result: /opt/local/Library/Frameworks/Python.framework/Versions/2.7
configure:5297: checking Python's execution prefix

clang: error: no such file or directory: 'Python.framework/Versions/2.7/Python'

Which suggests that this is related to #39223

This was fixed in r110123. Clean, run selfupdate, and build again.

That did not seem to improve things:

wichert@zephyr ~ $ vim -v
Vim: Caught deadly signal SEGV
Vim: Finished.
Segmentation fault: 11

[larryv (Lawrence Velázquez)]

Please attach your main.log and config.log:

% sudo port clean vim
% sudo port configure vim
% echo $(port logfile vim)
% echo $(port work vim)/vim*/config.log

[wichert@…]

Attached. Both vim and MacVim show the same segfault.

[wichert@…]

I also noticed the existing binary builds for vim were made before r110123 landed and are thus missing python support.

Sorry, I gave you the wrong command. You need to run this.

sudo port configure vim +python27

No, they were not. r110123 bumped vim to @7.3.762_3, which ​has been built.

and are thus missing python support.

We only generate binary archives for default variants, which do not include any of the Python variants.

[wichert@…]

The segfaults appears to be related to the variants. Install vim +python27 works correctly now, but vim +python27 +ruby will segfault immediately on startup.

[wichert@…]

main log for +python27 +ruby

[wichert@…]

config.log for +python27 +ruby

[larryv (Lawrence Velázquez)]

Does vim +ruby segfault?

[wichert@…]

vim +ruby indeed also segfaults.

[wichert@…]

vim +ruby19 also segfaults.

[larryv (Lawrence Velázquez)]

Okay, please open a new ticket specifically about the Ruby issue.
