libgcc-s-dev should include crtbegin/crtend/libgcc binaries about meta-sourcery HOT 7 OPEN

Nicely spotted, thanks for the report. I'll take a look. I tried to make use of existing .inc's in the core where possible, but the external toolchain sysroot extraction requires more explicit specification than the core recipes do. I'm assuming this is against current master?

from meta-sourcery.

It's against release/2014.12. Using that branch for now. I'll recheck with the master branch tomorrow.
I have a patch/workaround locally, but I'd like to give it a test before posting.

Created SB-4841, if that matters

Okay, that's good to know. The recipes were completely reworked in master to use separate recipes for each upstream recipe (e.g. libgcc-external is its own recipe) with an entirely different mechanism for the file extraction from the external toolchain sysroot. Regardless, fixing this should just be a matter of adding a few entries to the FILES variable in question in the external-sourcery-toolchain recipe.

Good to know. This should give us more flexibility. Unfortuntately ATM I'm stuck with release 2014.12.

Regarding FILES_* variables. Not quite. To be as compatible as possible I'm also installing files to a gcc-specific folders, not to /usr/lib. On the other hand just putting everything to /usr/lib should also work. I'll give it a try.

@kergoth Installing these files to /usr/lib has serious drawback --- they will go now to libc6-dev package instead of libgcc-dev. I'll do few more tests.

@kergoth just FYI. I ended up with the following snippet:

def sourcery_get_libroot(d):
    import subprocess
    libroot_cmd = "${TARGET_PREFIX}gcc ${TARGET_CC_ARCH} -print-file-name=crtbegin.o"
    try:
        toolchain_libroot = bb.process.run(bb.data.expand(libroot_cmd, d),
                                           stderr=subprocess.PIPE,
                                           env={"PATH": d.getVar('PATH', True)})[0].rstrip()[:-11]
    except bb.process.CmdError as exc:
        bb.fatal(str(exc))
    else:
        return toolchain_libroot

EXTERNAL_TOOLCHAIN_LIBROOT = "${@sourcery_get_libroot(d)}"

do_install_append() {
        install -d ${D}/usr/lib/${TARGET_SYS}/${CSL_VER_GCC}
        for file in crtbegin.o crtbeginS.o crtendT.o crtend.o crtendS.o libgcc.a libgcc_eh.a ; do
                if [ -e "${EXTERNAL_TOOLCHAIN_LIBROOT}"/$file ]; then
                        install -m 0644 "${EXTERNAL_TOOLCHAIN_LIBROOT}"/$file ${D}/usr/lib/${TARGET_SYS}/${CSL_VER_GCC}
                fi
        done
}

FILES_libgcc-dev += "${libdir}/${TARGET_SYS}/${CSL_VER_GCC}"
INSANE_SKIP_libgcc-dev = "staticdev"

pkg_postinst_libgcc-dev () {
        for file in crtbegin.o crtbeginS.o crtendT.o crtend.o crtendS.o libgcc.a libgcc_eh.a ; do
                ln -s /usr/lib/${TARGET_SYS}/${CSL_VER_GCC}/$file ${libdir}
        done
}
