sys-libs/glibc: Add new bootstrap files from stages, bug 647070 See https://github.com/gentoo/gcc-multilib-bootstrap/ for the source. This is as good as we can do at the moment. Tested by building an x32 glibc on a normal amd64 system. For the glibc-2.26 stabilization we still need new files for PowerPC. Current status: * amd64, x32, x86: Files from gcc-6.4 * s390, s390x: Files from gcc-5.4 (does this work?) * ppc, ppc64: no files, since only gcc-4.9 available * n32, n64, o32: no files, last mips stages are years old, not useful Bug: https://bugs.gentoo.org/647070 Package-Manager: Portage-2.3.31, Repoman-2.3.9 sys-libs/glibc/Manifest | 1 + .../{glibc-9999.ebuild => glibc-2.26-r7.ebuild} | 829 ++++----------------- .../{glibc-9999.ebuild => glibc-2.27-r2.ebuild} | 20 +- sys-libs/glibc/glibc-9999.ebuild | 8 +- 4 files changed, 148 insertions(+), 710 deletions(-) diff --git a/sys-libs/glibc/Manifest b/sys-libs/glibc/Manifest index 71fdce7bee9..767c577845d 100644 --- a/sys-libs/glibc/Manifest +++ b/sys-libs/glibc/Manifest @@ -1,4 +1,5 @@ DIST gcc-4.7.3-r1-multilib-bootstrap.tar.bz2 8064097 BLAKE2B 3cc5c82cd57d0fbd26d9a376ee8ca02f119fe9d653311cbe4d2b7b93aec2290adac3be271be19a7fdedae2e11e4b6e32360184e557204e100ad64357f5575d4b SHA512 40b93e194ad41a75d649d84d1c49070680f253a13f0617803243bc61c44fed1ca2d0a7572a97ebb79353f312b58b5f6360be916dd7435928cc53935082e15269 +DIST gcc-multilib-bootstrap-20180501.tar.xz 2128700 BLAKE2B edeb5447bf397dfeee1295beb10b0e34253da8b3e1816720b6cfc3300a1c685fa022c3b809402a86340bbd7b9488d22cfba4c042d530dcb05ec971a2b1580d34 SHA512 eb289c44c5dcabaa727612dd685801b61e1fbe94b39024ecb3e14c73f9eaff68e05949a8f277a86c7471955cc8ec6e0127623b9861be7ac85f63226618b6c9c2 DIST glibc-2.18-patches-4.tar.bz2 95165 BLAKE2B 70280e0f5fd0b1ee13cd0464aafaa9c9324528d0bee8024e6529d67d908991012066db6d8257b66983a1f52e32b3aad7718612fdab9ea199fef845db93347168 SHA512 d881c9c5fe32b967694d4ca5185ff5ffc964449f2ed49fd062e5d57a3c6d9f16eef2f591d2d8e98a1a95a6487f3436ef031839ed8766fd085404b288340b7933 DIST glibc-2.18.tar.xz 11150148 BLAKE2B 7848a5a50abedbd17085e05b6f6835959adb5e55a424d95fa8a49eeec999a6dd81a9382db85ef7e852ef1d7743c5d312dccbf42024e95edf0e802eb32928dfe5 SHA512 27218d2e7dd3bf3908d7af171c490933680e958c579ebd27b43b661e223fd5de2219cc1cf699170405280808c84de476d0ad86dbba35a488ef404e9438552327 DIST glibc-2.19-patches-3.tar.bz2 80664 BLAKE2B fb348c711941c1bd4dadd905e172dc4f239d8b63af1a1d14dcf4ec45c504bd47e10e9b24b38f9e01796016f2e97caeeb693213ae08147274ed0a4d9501293be0 SHA512 d281d6a2757920124cf8a3f02b97e75192598b08d96ae48840df34c7ffdcb212952d171f233e6f12a429b19437d0a296212fe1f2eae164d6a1c6793cb3cb69f0 diff --git a/sys-libs/glibc/glibc-9999.ebuild b/sys-libs/glibc/glibc-2.26-r7.ebuild similarity index 50% copy from sys-libs/glibc/glibc-9999.ebuild copy to sys-libs/glibc/glibc-2.26-r7.ebuild index ca23762e8d4..dad9a620a2c 100644 --- a/sys-libs/glibc/glibc-9999.ebuild +++ b/sys-libs/glibc/glibc-2.26-r7.ebuild @@ -3,40 +3,40 @@ EAPI=6 -inherit prefix eutils versionator toolchain-funcs flag-o-matic gnuconfig \ - multilib systemd multiprocessing +inherit prefix toolchain-glibc DESCRIPTION="GNU libc C library" HOMEPAGE="https://www.gnu.org/software/libc/"; + LICENSE="LGPL-2.1+ BSD HPND ISC inner-net rc PCRE" RESTRICT="strip" # Strip ourself #46186 -SLOT="2.2" - EMULTILIB_PKG="true" +# Configuration variables + if [[ ${PV} == 9999* ]]; then - EGIT_REPO_URI="https://sourceware.org/git/glibc.git"; + EGIT_REPO_URI="git://sourceware.org/git/glibc.git" inherit git-r3 else - # KEYWORDS="~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86" + #KEYWORDS="~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86" KEYWORDS="" SRC_URI="mirror://gnu/glibc/${P}.tar.xz" fi RELEASE_VER=${PV} -GCC_BOOTSTRAP_VER="4.7.3-r1" +GCC_BOOTSTRAP_VER=20180501 # Gentoo patchset -PATCH_VER=5 +PATCH_VER=7 SRC_URI+=" https://dev.gentoo.org/~dilfridge/distfiles/${P}-patches-${PATCH_VER}.tar.bz2"; -SRC_URI+=" multilib?
