I've installed igraph on older Macs many times, but seem to having a particular bit of trouble this time. Here is some background:
Configuration: --OS X 10.11.6 Captain -- Python 2.7 (location: /Library/Python/2.7 ) -------------------- from page: http://igraph.org/python/doc/tutorial/install.html --- Tried to use OS X binary installer, but installation failed -------------------- from http://igraph.org/c/ -- download/install C-core % ./configure % make % make install Next -------------------- % easy_install python-igraph Searching for python-igraph Reading https://pypi.python.org/simple/python-igraph/ Best match: python-igraph 0.7.1.post6 Downloading https://pypi.python.org/packages/0f/a0/4e7134f803737aa6eebb4e5250565ace0e2599659e22be7f7eba520ff017/python-igraph-0.7.1.post6.tar.gz#md5=a4c0b5960735b36adb5d3a40031cb7c0 Processing python-igraph-0.7.1.post6.tar.gz Writing /var/folders/d8/m2pf957d6ggc9s8yycvc2wsm0000gp/T/easy_install-zmpkEv/python-igraph-0.7.1.post6/setup.cfg Running python-igraph-0.7.1.post6/setup.py -q bdist_egg --dist-dir /var/folders/d8/m2pf957d6ggc9s8yycvc2wsm0000gp/T/easy_install-zmpkEv/python-igraph-0.7.1.post6/egg-dist-tmp-NsmNx7 Cannot find the C core of igraph on this system using pkg-config. We will now try to download and compile the C core from scratch. Version number of the C core: 0.7.1.post6 We will also try: 0.7.1 Version 0.7.1.post6 of the C core of igraph is not found among the nightly builds. Use the --c-core-version switch to try a different version. Could not download and compile the C core of igraph. error: Setup script exited with 1 ------------ Any insight into what I may be doing wrong? Thanks in advance, Dave Robinson
