Oops, sorry, yes. I mean --help, which is the test used in gcc/configure in the 4.6 branch: elif $ORIGINAL_PLUGIN_LD_FOR_TARGET --help 2>/dev/null | grep plugin-opt > /dev/null; then > Does your gold --help show --plugin-opt? No: $ ~/tools/Linux-x86_64/lto/bin/ld --help | fgrep plugin $ ~/tools/Linux-x86_64/lto/bin/ld.gold --help | fgrep plugin $ ~/tools/Linux-x86_64/lto/bin/ld.gold --version GNU gold (GNU Binutils 2.21) 1.10 Copyright 2010 Free Software Foundation, Inc.

But ld.bfd from the same build does: $ ~/tools/Linux-x86_64/lto/bin/ld.bfd --help | fgrep plugin -plugin PLUGIN Load named plugin -plugin-opt ARG Send arg to last-loaded plugin That's why I suggested I could solve my problem by using --with-plugin-ld=blahblah/ld.bfd, because the "ld --help | fgrep plugin-opt" test would work. > It should.

Not intentionally, no: $ head ~/src/gcc/binutils-2.21/config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by configure, which was generated by GNU Autoconf 2.64. Invocation command line was $ ./configure --prefix=/home/wakelj/tools/Linux-x86_64/lto --enable-lto --enable-gold=default Thanks for the answers, I now know that what I'm seeing is indeed odd so that's why I was surprised. I'll try to get to the bottom of why gold has plugins disabled but ld.bfd doesn't.
