config.log (text/plain), 146.65 KB, created by Patrik Osgnach on 2019-01-25 13:46:01 UTC

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by fftw configure 3.3.6-pl2, which was
generated by GNU Autoconf 2.69.  Invocation command line was
