--- Comment #10 from vries at gcc dot gnu.org --- Looking at the description of with-host-libstdcxx: ... --with-host-libstdcxx=linker-args If you are linking with a static copy of PPL, you can use this option to specify how the linker should find the standard C++ library used internally by PPL. Typical values of linker-args might be ‘-lstdc++’ or ‘-Wl,-Bstatic,-lstdc++,-Bdynamic -lm’. If you are linking with a shared copy of PPL, you probably do not need this option; shared library dependencies will cause the linker to search for the standard C++ library automatically. ... We no longer support building with PPL ( https://gcc.gnu.org/ml/gcc-patches/2012-06/msg01773.html ), so this doc item probably needs to be updated.
