This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by utun configure 2.0.0, which was generated by GNU Autoconf 2.71. Invocation command line was $ ../configure --no-create --no-recursion ## --------- ## ## Platform. ## ## --------- ## hostname = user-Standard-PC-i440FX-PIIX-1996 uname -m = x86_64 uname -r = 6.14.0-37-generic uname -s = Linux uname -v = #37~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 20 10:25:38 UTC 2 /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/vnc1/.cargo/bin/ 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/ PATH: /snap/bin/ PATH: /snap/bin/ ## ----------- ## ## Core tests. ## ## ----------- ## configure:2453: looking for aux files: config.guess config.sub missing install-sh ar-lib compile configure:2466: trying ../build-aux/ configure:2495: ../build-aux/config.guess found configure:2495: ../build-aux/config.sub found configure:2495: ../build-aux/missing found configure:2477: ../build-aux/install-sh found configure:2495: ../build-aux/ar-lib found configure:2495: ../build-aux/compile found configure:2675: checking for gcc configure:2696: found /usr/bin/gcc configure:2707: result: gcc configure:3060: checking for C compiler version configure:3069: gcc --version >&5 gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0 Copyright (C) 2023 Free Software Foundation, Inc.
