This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by python configure 3.7, which was generated by GNU Autoconf 2.69. Invocation command line was $ ./configure --target=powerpc-buildroot-linux-uclibc --host=powerpc-buildroot-linux-uclibc --build=x86_64-pc-linux-gnu --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --localstatedir=/var --program-prefix= --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no --disable-dependency-tracking --enable-ipv6 --disable-nls --disable-static --enable-shared --disable-readline --disable-curses --with-libmpdec=none --with-expat=system --disable-codecs-cjk --disable-unicodedata --disable-uuid --disable-bzip2 --disable-xz --disable-ossaudiodev --without-ensurepip --without-cxx-main --with-system-ffi --disable-pydoc --disable-test-modules --disable-lib2to3 --disable-tk --disable-nis --disable-idle3 --disable-pyc-build ## --------- ## ## Platform. ## ## --------- ## hostname = armadeuspe uname -m = x86_64 uname -r = 3.13.0-147-generic uname -s = Linux uname -v = #196-Ubuntu SMP Wed May 2 15:51:34 UTC 2018 /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/buildroot/buildroot-test/instance-1/output/host/bin PATH: /home/buildroot/buildroot-test/instance-1/output/host/sbin PATH: /usr/local/sbin PATH: /usr/local/bin PATH: /usr/sbin PATH: /usr/bin PATH: /sbin PATH: /bin PATH: /usr/games PATH: /usr/local/games ## ----------- ## ## Core tests. ## ## ----------- ## configure:2854: checking build system type configure:2868: result: x86_64-pc-linux-gnu configure:2888: checking host system type configure:2901: result: powerpc-buildroot-linux-uclibc configure:2931: checking for python3.7 configure:2947: found /home/buildroot/buildroot-test/instance-1/output/host/bin/python3.7 configure:2958: result: python3.7 configure:2973: checking for python interpreter for cross build configure:2986: result: python3.7 configure:3052: checking for --enable-universalsdk configure:3099: result: no configure:3122: checking for --with-universal-archs configure:3137: result: no configure:3293: checking MACHDEP configure:3499: checking for --without-gcc configure:3522: result: no configure:3525: checking for --with-icc configure:3545: result: no configure:3629: checking for powerpc-buildroot-linux-uclibc-gcc configure:3656: result: /home/buildroot/buildroot-test/instance-1/output/host/bin/powerpc-buildroot-linux-uclibc-gcc configure:3925: checking for C compiler version configure:3934: /home/buildroot/buildroot-test/instance-1/output/host/bin/powerpc-buildroot-linux-uclibc-gcc --version >&5 powerpc-buildroot-linux-uclibc-gcc.br_real (Buildroot 2019.08-git-00600-ged3eef6) 8.3.0 Copyright (C) 2018 Free Software Foundation, Inc.
