Bug 508008 – sys-devel/crossdev: overlay search does not consider requested versions

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Andrew Aladjev 2014-04-18 13:34:24 UTC]

Hello. I want to create aarch64 crossdev environment today. I need gcc-4.9 from toolchain overlay and binutils-9999 from core gentoo overlay.

1. if I will add toolchain overlay to PORTDIR_OVERLAY:

 * getting sys-devel/binutils from /var/lib/layman/toolchain
 * getting sys-devel/gcc from /var/lib/layman/toolchain
 * getting sys-libs/glibc from /var/lib/layman/toolchain
 * getting sys-devel/gdb from /var/lib/layman/toolchain

but there are no binutils-9999 in toolchain overlay.

2. if I will not add toolchain overlay to PORTDIR_OVERLAY - there are no gcc-4.9 in core gentoo overlay

The problem is the part of "set_links" function:

for s in ${ovl} ${SEARCH_OVERLAYS} ; do
  if [[ -d ${s}/${cat}/${pkg} ]] ; then
    srcdir=${s}
    einfo "getting ${cat}/${pkg} from ${srcdir}"
    break
  fi
done

This code do not care about package's version. Please consider attached patch.

Reproducible: Always

Crossdev is not part of portage, but is its own package.  Re-assigning to the maintainer.

this doesn't work with version strings like ~4.8.1 or =4.9*

This got a bit better with the following (although I don't think it's perfect):

    crossdev: don't pick ebuild version from overlay if unmatching KEYWORDS

    We don't want to e.g. pick a GCC from an overlay if it doesn't
    have KEYWORDS for our target, which then leads to an early
    crossdev failure as it obviously can't then emerge GCC.

    crossdev: Fall back to default version for gdb too

    Passing `--stable` didn't affect the version of built GDB, thus we
    needed to pass `--gdb '[stable]'` on our own.

    crossdev: Fix matching of stable keywords

    Not sure how this worked before - in our case emerge couldn't find a
    matching ebuild any more when requesting stable versions.
