This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by libndp configure 1.8, which was generated by GNU Autoconf 2.71. Invocation command line was $ ./configure --target=or1k-buildroot-linux-uclibc --host=or1k-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 --enable-static --enable-shared ## --------- ## ## Platform. ## ## --------- ## hostname = build3.bootlin.com uname -m = x86_64 uname -r = 5.4.0-124-generic uname -s = Linux uname -v = #140-Ubuntu SMP Thu Aug 4 02:23:37 UTC 2022 /usr/bin/uname -p = x86_64 /bin/uname -X = unknown /bin/arch = x86_64 /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/thomas/autobuild/instance-1/output-1/host/bin/ PATH: /home/thomas/autobuild/instance-1/output-1/host/sbin/ PATH: /usr/local/sbin/ PATH: /usr/local/bin/ PATH: /usr/sbin/ PATH: /usr/bin/ PATH: /sbin/ PATH: /bin/ PATH: /snap/bin/ ## ----------- ## ## Core tests. ## ## ----------- ## configure:2399: looking for aux files: config.guess config.sub ltmain.sh compile ar-lib missing install-sh configure:2412: trying ./build-aux/ configure:2441: ./build-aux/config.guess found configure:2441: ./build-aux/config.sub found configure:2441: ./build-aux/ltmain.sh found configure:2441: ./build-aux/compile found configure:2441: ./build-aux/ar-lib found configure:2441: ./build-aux/missing found configure:2423: ./build-aux/install-sh found configure:2572: checking for a BSD-compatible install configure:2645: result: /usr/bin/install -c configure:2656: checking whether build environment is sane configure:2711: result: yes configure:2765: checking for or1k-buildroot-linux-uclibc-strip configure:2797: result: /bin/true configure:2868: checking for a race-free mkdir -p configure:2912: result: /usr/bin/mkdir -p configure:2919: checking for gawk configure:2940: found /usr/bin/gawk configure:2951: result: gawk configure:2962: checking whether make sets $(MAKE) configure:2985: result: yes configure:3015: checking whether make supports nested variables configure:3033: result: yes configure:3181: checking whether make supports nested variables configure:3199: result: yes configure:3223: checking whether make supports the include directive configure:3238: make -f confmf.GNU && cat confinc.out make[1]: Entering directory '/home/thomas/autobuild/instance-1/output-1/build/libndp-1.8' make[1]: Leaving directory '/home/thomas/autobuild/instance-1/output-1/build/libndp-1.8' this is the am__doit target configure:3241: $? = 0 configure:3260: result: yes (GNU style) configure:3291: checking for or1k-buildroot-linux-uclibc-gcc configure:3323: result: /home/thomas/autobuild/instance-1/output-1/host/bin/or1k-buildroot-linux-uclibc-gcc configure:3721: checking for C compiler version configure:3730: /home/thomas/autobuild/instance-1/output-1/host/bin/or1k-buildroot-linux-uclibc-gcc --version >&5 or1k-buildroot-linux-uclibc-gcc.br_real (Buildroot 2022.05.1-122-g1f4a9dbebc) 9.4.0 Copyright (C) 2019 Free Software Foundation, Inc.
