[gentoo-dev] Standalone libstdc++

[Казанков Александр Владимирович]

Hello.

I wish to compile library libstdc ++ being based on
sys-dev/gcc/gcc-4.3.2-r3.ebuild:

src_compile() {

    gcc_do_filter_flags
    einfo "CFLAGS=\"${CFLAGS}\""
    einfo "CXXFLAGS=\"${CXXFLAGS}\""

    # Build in a separate build tree
    mkdir -p "${WORKDIR}"/build
    pushd "${WORKDIR}"/build > /dev/null

    einfo "Configuring ${PN} ..."
    gcc_do_configure

    touch "${S}"/gcc/c-gperf.h

    einfo "Compiling ${PN} ..."
    gcc_do_make all-target-libstdc++-v3

    popd > /dev/null

}


But compilation does not pass successfully:

Such sensation that the prefix of a place of assemblage vanishes. That's
bug!?
