--- Comment #11 from vries at gcc dot gnu.org --- (In reply to vries from comment #10) > 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. --with-host-libstdcxx=linker-args Sets default value for --with-stage1-libs and --with-boot-libs. Sets default value for --with-boot-ldflags to empty.
