This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by Protocol Buffers configure 3.6.0, which was generated by GNU Autoconf 2.69. Invocation command line was $ ./configure --prefix=/home/peko/autobuild/instance-0/output/host --sysconfdir=/home/peko/autobuild/instance-0/output/host/etc --localstatedir=/home/peko/autobuild/instance-0/output/host/var --enable-shared --disable-static --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --disable-debug --with-xmlto=no --with-fop=no --disable-dependency-tracking ## --------- ## ## Platform. ## ## --------- ## hostname = gcc20 uname -m = x86_64 uname -r = 3.2.0-4-amd64 uname -s = Linux uname -v = #1 SMP Debian 3.2.63-2+deb7u2 /usr/bin/uname -p = unknown /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: /home/peko/autobuild/instance-0/output/host/bin PATH: /home/peko/autobuild/instance-0/output/host/sbin PATH: /home/peko/host/usr/bin PATH: /usr/local/bin PATH: /usr/bin PATH: /bin PATH: /usr/local/games PATH: /usr/games ## ----------- ## ## Core tests. ## ## ----------- ## configure:2620: checking whether to enable maintainer-specific portions of Makefiles configure:2629: result: yes configure:2704: checking build system type configure:2718: result: x86_64-pc-linux-gnu configure:2738: checking host system type configure:2751: result: x86_64-pc-linux-gnu configure:2771: checking target system type configure:2784: result: x86_64-pc-linux-gnu configure:2827: checking for a BSD-compatible install configure:2895: result: /usr/bin/install -c configure:2906: checking whether build environment is sane configure:2961: result: yes configure:3112: checking for a thread-safe mkdir -p configure:3151: result: /bin/mkdir -p configure:3158: checking for gawk configure:3174: found /usr/bin/gawk configure:3185: result: gawk configure:3196: checking whether make sets $(MAKE) configure:3218: result: yes configure:3247: checking whether make supports nested variables configure:3264: result: yes configure:3353: checking whether UID '1043' is supported by ustar format configure:3356: result: yes configure:3363: checking whether GID '1043' is supported by ustar format configure:3366: result: yes configure:3374: checking how to create a ustar tar archive configure:3385: tar --version tar (GNU tar) 1.29 Copyright (C) 2015 Free Software Foundation, Inc.
