OS X Python Installation Instructions about vizdoom

[SimsGautam]

I get the following error when trying to install in OSX:
ld: library not found for -lrt
clang: error: linker command failed with exit code 1

This is near to impossible. Are you sure you have the most recent version from the master? Pull it once again. Then execute cmake_clean.sh. Then try again cmake . && make and let me know.

@SimsGautam Also make sure you've opened Xcode before and accepted the ToS. Without doing so many random things will break.

EDIT: I believe you can also use sudo xcodebuild -license.

Thanks for this, I'm having trouble running the the example:

  File "/usr/local/bin/../Cellar/python/2.7.11/bin/../Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 548, in <module>
    main()
  File "/usr/local/bin/../Cellar/python/2.7.11/bin/../Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 530, in main
    known_paths = addusersitepackages(known_paths)
  File "/usr/local/bin/../Cellar/python/2.7.11/bin/../Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 266, in addusersitepackages
    user_site = getusersitepackages()
  File "/usr/local/bin/../Cellar/python/2.7.11/bin/../Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 241, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE
  File "/usr/local/bin/../Cellar/python/2.7.11/bin/../Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 231, in getuserbase
    USER_BASE = get_config_var('userbase')
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 520, in get_config_var
    return get_config_vars().get(name)
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 453, in get_config_vars
    import re
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/re.py", line 108, in <module>
    import _locale

Any ideas?

Well, I assume that you get SystemError: dynamic module not initialized properly at the end of the output you have shown, right? Then, it is related to #45 and it means that something is wrong with your python. I can see that you are using brew'ed python. I use macports so I cannot check myself but for many people using brew the instruction in #46 did the trick. Could you try it and let me know?

Thanks, cmake definitely found my brew'd Python but then I get this on running make

It seems that your PYTHON_INCLUDE_DIR was set incorrectly. To verify this:

Find PYTHON_INCLUDE_DIR= in CMakeCache.txt (e.g., PYTHON_INCLUDE_DIR:PATH=/usr/include/python2.7) and check whether it contains Python.h:

ls -l /usr/include/python2.7/ | grep Python.h

It probably does not, so you need to set it correctly according to your system as it reads in the "compiling" section: https://github.com/Marqt/ViZDoom/blob/b0dbb4f74d936bd6ad304515395d887fb58d4ad4/README.md#compiling-2

Let me know whether this helped

Got it working. The relevant include folder for brew Python is /include/python/2.7 so this line in the readme should be DPYTHON_INCLUDE_DIR=/usr/local/Cellar/python/2.x.x/Frameworks/Python.framework/Versions/2.7/include/python2.7 instead of DPYTHON_INCLUDE_DIR=/usr/local/Cellar/python/2.x.x/Frameworks/Python.framework/Versions/2.7/include (note the additional directory at the end).

Thanks for the help, super excited now.

Thx for letting us know!
