1-config.log

1-config.log (text/plain), 93.32 KB, created by Agostino Sarubbo on 2020-08-19 04:54:11 UTC

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

It was created by graph-tool configure 2.29, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/graph-tool-2.29 --htmldir=/usr/share/doc/graph-tool-2.29/html --with-sysroot=/ --libdir=/usr/lib64 --disable-static --enable-openmp --enable-cairo --with-boost-python=boost_python37
