This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by GNU C Library configure (see version.h), which was generated by GNU Autoconf 2.71. Invocation command line was $ /home/buildroot/autobuild/instance-2/output-1/build/glibc-2.39-74-g198632a05f6c7b9ab67d3331d8caace9ceabb685/configure --target=riscv64-buildroot-linux-gnu --host=riscv64-buildroot-linux-gnu --build=x86_64-pc-linux-gnu --prefix=/usr --enable-shared --with-pkgversion=Buildroot --disable-profile --disable-werror --without-gd --with-headers=/home/buildroot/autobuild/instance-2/output-1/host/riscv64-buildroot-linux-gnu/sysroot/usr/include --enable-kernel=5.10 ## --------- ## ## Platform. ## ## --------- ## hostname = br-autobuild-1.osuosl.org uname -m = x86_64 uname -r = 6.0.11-300.fc37.x86_64 uname -s = Linux uname -v = #1 SMP PREEMPT_DYNAMIC Fri Dec 2 20:47:45 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/buildroot/autobuild/instance-2/output-1/host/bin/ PATH: /home/buildroot/autobuild/instance-2/output-1/host/sbin/ PATH: /usr/local/sbin/ PATH: /usr/local/bin/ PATH: /usr/sbin/ PATH: /usr/bin/ ## ----------- ## ## Core tests. ## ## ----------- ## configure:2651: looking for aux files: install-sh config.guess config.sub configure:2664: trying /home/buildroot/autobuild/instance-2/output-1/build/glibc-2.39-74-g198632a05f6c7b9ab67d3331d8caace9ceabb685/scripts/ configure:2675: /home/buildroot/autobuild/instance-2/output-1/build/glibc-2.39-74-g198632a05f6c7b9ab67d3331d8caace9ceabb685/scripts/install-sh found configure:2693: /home/buildroot/autobuild/instance-2/output-1/build/glibc-2.39-74-g198632a05f6c7b9ab67d3331d8caace9ceabb685/scripts/config.guess found configure:2693: /home/buildroot/autobuild/instance-2/output-1/build/glibc-2.39-74-g198632a05f6c7b9ab67d3331d8caace9ceabb685/scripts/config.sub found configure:2890: checking build system type configure:2905: result: x86_64-pc-linux-gnu configure:2925: checking host system type configure:2939: result: riscv64-buildroot-linux-gnu configure:2977: checking for riscv64-buildroot-linux-gnu-gcc configure:3009: result: /home/buildroot/autobuild/instance-2/output-1/host/bin/riscv64-buildroot-linux-gnu-gcc configure:3407: checking for C compiler version configure:3416: /home/buildroot/autobuild/instance-2/output-1/host/bin/riscv64-buildroot-linux-gnu-gcc --version >&5 riscv64-buildroot-linux-gnu-gcc.br_real (Buildroot 2024.05.3) 14.2.0 Copyright (C) 2024 Free Software Foundation, Inc.
