无法从源代码构建 GCC 10

Question

On Oracle Linux, I'm trying to build a GCC toolchain from the following:

• GCC 10.1.0
• binutils 2.34
• GDB 9.2.0

All of these are the latest released sources as of today. I've configured like so:

../gcc10-toolchain/configure \
    --prefix=/opt/gcc10-toolchain \
    --with-diagnostics-color=auto \
    --with-system-zlib \
    --with-system-lzma \
    --enable-languages="c,c++,lto" \
    --enable-shared \
    --enable-static \
    --enable-gold=default \
    --enable-install-libbfd \
    --enable-plugins \
    --enable-default-pie \
    --enable-linker-build-id \
    --enable-threads=posix \
    --enable-checking=release \
    --enable-__cxa_atexit \
    --enable-initfini-array \
    --enable-gnu-indirect-function \
    --enable-tui \
    --enable-bootstrap \
    --disable-multilib \
    --disable-libgcj \
    --disable-nls \
    --disable-lto \
    --disable-libstdcxx-debug

However, when building with make , I get the following errors:

../../gcc10-toolchain/gcc/lto-streamer-out.c: In function ‘void write_symbol_extension_info(tree)’: ../../gcc10-toolchain/gcc/lto-streamer-out.c:2790:10: error: ‘GCCST_VARIABLE’ was not declared in this scope
        ? GCCST_VARIABLE : GCCST_FUNCTION);
          ^ ../../gcc10-toolchain/gcc/lto-streamer-out.c:2790:27: error: ‘GCCST_FUNCTION’ was not declared in this scope
        ? GCCST_VARIABLE : GCCST_FUNCTION);
                           ^ ../../gcc10-toolchain/gcc/lto-streamer-out.c:2797:18: error: ‘GCCSSK_BSS’ was not declared in this scope   section_kind |= GCCSSK_BSS;

Unfortunately I could not find anything on this online, and have no idea where to even begin looking.

Answer 1

The issue was the order in which I copied the sources together. binutils-2.34 is older than gcc-10.1.0, and so gcc-10.1.0 be copied in last so that it overwrites the files shared with binutils, not the other way around.
