setup.py build_ext se fails

[MiBu84]

Executed successfully all steps up to "6. Build the Python extension:"

My config:

• CentOS 7 (uname -r --> 4.19.7-1.el7.elrepo.x86_64), -gcc -v --> gcc-Version 4.8.5 20150623 (Red Hat 4.8.5-36) (also tried 5.4, 8.2)
• python --version --> Python 3.6.5

However when now trying "python3.6 setup.py build_ext", I receive: unning build_ext Package fplll was not found in the pkg-config search path.

You are missing GMP headers on your system. The relevant package will be called gmp-dev or libgmp-devel or so.

[MiBu84]

But I installed gmp (6.1.2) already and the Libs are in LD_LIBRARY_PATH/LIBRARY_PATH and the headers in CPATH. It is e.g. detected when compiling fplll directly or other costum projects requiring gmp.h during compilation and the library during linking.

Closing this, it doesn't seem like a bug in fpylll. Feel free to reopen if you're convinced it is.
