Same issue on Ubuntu 16.04 and Centos 7, although no pkg-config errors. The suggestion in this issue fixes it - #85

Eg:

git reset --hard 95ba42158eb46153944d5abc3bcb62f40e384186
make

@david-poirier-csn:

Same issue on Ubuntu 16.04 and Centos 7, although no pkg-config errors.

This sounds then like a different issue. If this still persists after #97, please open a new issue and paste a complete log of the failing build.

@sunatthegilddotcom

First, please try the current version (after #97 was merged). If that doesn't work, please try running pkg-config. If that command is not found, please see if installing as follows helps:

sudo apt-get install pkg-config

Current version (post-#97) works for me now, on Ubuntu 16.04 and Centos 7.

@david-poirier-csn your solution is working. Thank you very much! @robryk, I followed your direction as well after David. Thank you
