It did compile as Richard suggested with 10.4 Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-pc-linux-gnu/10.4.0/lto-wrapper Target: x86_64-pc-linux-gnu Configured with: ./configure --with-mpc-lib= --disable-multilib Thread model: posix Supported LTO compression algorithms: zlib zstd gcc version 10.4.0 (GCC) the preprocessed file was after installing 10.4.
