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 ## --------- ## ## Platform. ## ## --------- ## hostname = localhost uname -m = x86_64 uname -r = 5.4.0-1021-aws uname -s = Linux uname -v = #21-Ubuntu SMP Fri Jul 24 09:42:29 UTC 2020 /usr/bin/uname -p = Intel(R) Xeon(R) Platinum 8175M CPU @ 2.50GHz /bin/uname -X = unknown /bin/arch = unknown /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown /usr/bin/hostinfo = unknown /bin/machine = unknown /usr/bin/oslevel = unknown /bin/universe = unknown PATH: /var/tmp/portage/dev-python/graph-tool-2.29/temp/python3.7/bin PATH: /usr/lib/portage/python3.7/ebuild-helpers/xattr PATH: /usr/lib/portage/python3.7/ebuild-helpers PATH: /usr/local/sbin PATH: /usr/local/bin PATH: /usr/sbin PATH: /usr/bin PATH: /sbin PATH: /bin PATH: /opt/bin PATH: /usr/lib/llvm/10/bin ## ----------- ## ## Core tests. ## ## ----------- ## configure:2714: checking build system type configure:2728: result: x86_64-pc-linux-gnu configure:2748: checking host system type configure:2761: result: x86_64-pc-linux-gnu configure:2781: checking target system type configure:2794: result: x86_64-pc-linux-gnu configure:2836: checking for a BSD-compatible install configure:2904: result: /usr/lib/portage/python3.7/ebuild-helpers/xattr/install -c configure:2915: checking whether build environment is sane configure:2970: result: yes configure:3119: checking for a thread-safe mkdir -p configure:3158: result: /bin/mkdir -p configure:3165: checking for gawk configure:3181: found /usr/bin/gawk configure:3192: result: gawk configure:3203: checking whether make sets $(MAKE) configure:3225: result: yes configure:3254: checking whether make supports nested variables configure:3271: result: yes configure:3350: checking how to create a pax tar archive configure:3361: tar --version tar (GNU tar) 1.32 Copyright (C) 2019 Free Software Foundation, Inc.
