libchess module missing on Mac OS X

[nallapan]

Hi, I am seeing this error on the Mac OSX. Followed all the steps. Am I missing some steps?

Yes, this issue was specifically covered in step 3 of the build - " If not running on Mac OS X, the libchess.so library needs to be built, go to https://github.com/sshivaji/python-chess, switch to the pgn branch. Then execute "sudo python setup.py install".

At some point I want to automate the steps and have a setup.py that does it all.

But I am running it on Mac OSX (Mavericks)

Typo in instructions, this needs to be run on all platforms. Libchess is not installed by default :) will fix instructions.

Now updated. The old instructions were a remnant from a while back.

Those days I had committed libchess.so to the source tree for Mac OS X users. Nowadays, due to different Mac OS X versions (e.g. 10.8 vs 10.9), its better to compile that library from scratch.

I've been struggling to install Kivy-Chess on my mac. I downloaded the libchess branch of Kivychess, and I've managed to overcome a number of obstacles, including figuring out how to compile libchess.so library, but still cannot manage to run the program. After ./run.sh, i recieve the following response:

Traceback (most recent call last): File "main.py", line 99, in from chess import libchess File "/Users/SpillTheTea/Documents/JDel Rio/Chess Games/Chess GUIs/kivy-chess-libchess/chess/init.py", line 30, in from libchess import START_FEN File "build/bdist.macosx-10.14-x86_64/egg/libchess.py", line 7, in File "build/bdist.macosx-10.14-x86_64/egg/libchess.py", line 6, in bootstrap ImportError: dlopen(/Users/SpillTheTea/Library/Caches/Python-Eggs/python_chess-0.0.5-py2.7-macosx-10.14-x86_64.egg-tmp/libchess.so, 2): Symbol not found: __ZN5boost6python17error_already_setD1Ev Referenced from: /Users/SpillTheTea/Library/Caches/Python-Eggs/python_chess-0.0.5-py2.7-macosx-10.14-x86_64.egg-tmp/libchess.so Expected in: flat namespace in /Users/SpillTheTea/Library/Caches/Python-Eggs/python_chess-0.0.5-py2.7-macosx-10.14-x86_64.egg-tmp/libchess.so

Which makes me think, that I may have compiled the libchess.so library wrong. I needed to change the setup.py file from python-chess, needed to link both the boost-regex and boost-python libraries, to directly point to the directory on my computer. Here are the libraries I specifically used: "/usr/local/Cellar/boost-python/1.68.0/lib/libboost_python27.dylib", "/usr/local/Cellar/boost/1.68.0/lib/libboost_regex.dylib",
