I am currently on an OSX Mountain Lion (10.8.4) distro, and I am seeing some version mismatch between erfa_python and erfa. Note that I also tested it on a virtual machine with Debian, where everything works no problem. Extra info below.\n\nHope you can help! Thanks,\n\nRutger\n\nThe error I get:\n\n(dev)[ vhaaster dhcp-195-218 ~/local/erfa ] python\nPython 2.7.5 (default, Oct 18 2013, 12:58:26) \n[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.75)] on darwin\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\n\n\u003e \u003e \u003e import _erfa\n\u003e \u003e \u003e Traceback (most recent call last):\n\u003e \u003e \u003e   File \"\u003cstdin\u003e\", line 1, in \u003cmodule\u003e\n\u003e \u003e \u003e ImportError: dlopen(/Users/vhaaster/env/dev/lib/python2.7/site-packages/_erfa.so, 2): Library not loaded: /Users/vhaaster/local/erfa/lib/liberfa.1.dylib\n\u003e \u003e \u003e   Referenced from: /Users/vhaaster/env/dev/lib/python2.7/site-packages/_erfa.so\n\u003e \u003e \u003e   Reason: Incompatible library version: _erfa.so requires version 2.0.0 or later, but liberfa.1.dylib provides version 0.0.0\n\u003e \u003e \u003e exit()\n\nI basically followed this instruction set to install erfa:\n    export INSTDIR=/Users/vhaaster/local/\n    git clone https://github.com/liberfa/erfa-fetch.git\n    cd erfa-fetch\n    python sofa_deriver.py\n    cd erfa\n    gcc -O2 -I. -c -fPIC _.c\n    gcc -shared -o liberfa.so *.o -lm\n    cp erfa_.h $INSTDIR/include/\n    cp liberfa.so $INSTDIR/lib/liberfa.so.1.0.0\n    ln -sf $INSTDIR/lib/liberfa.so.1.0.0 $INSTDIR/lib/liberfa.dylib\n    ln -sf $INSTDIR/lib/liberfa.so.1.0.0 $INSTDIR/lib/liberfa.1.dylib\n","author":{"url":"https://github.com/vhaasteren","@type":"Person","name":"vhaasteren"},"datePublished":"2014-01-29T00:43:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":24},"url":"https://github.com/4/erfa_python/issues/4"}
