1-config.log (text/plain), 35.77 KB, created by Agostino Sarubbo on 2021-02-05 06:59:06 UTC

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

It was created by configure, which was
generated by GNU Autoconf 2.69.  Invocation command line was
