Note # that this variable is only important for a brief period of time, # before your source files get picked up by mirrors. However, it is # still highly suggested that you keep files in this location # available. # # BRANCH_UPDATE # If set, this variable signals that we should be using the main # release tarball (determined by ebuild version) and applying a # CVS branch update patch against it. The location of this branch # update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}. # Just like with SNAPSHOT, this variable is ignored if the ebuild # has a _pre suffix. # # PATCH_VER # PATCH_GLIBC_VER # This should be set to the version of the gentoo patch tarball. # The resulting filename of this tarball will be: # glibc-${PATCH_GLIBC_VER:-${GLIBC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2 # # GLIBC_MANPAGE_VERSION # GLIBC_INFOPAGE_VERSION # The version of glibc for which we will download pages. This will # default to ${GLIBC_RELEASE_VER}, but we may not want to pre-generate man pages # for prerelease test ebuilds for example. This allows you to # continue using pre-generated manpages from the last stable release. # If set to "none", this will prevent the downloading of manpages, # which is useful for individual library targets. # get_glibc_src_uri() { GENTOO_TOOLCHAIN_BASE_URI=${GENTOO_TOOLCHAIN_BASE_URI:-"mirror://gentoo"} GLIBC_SRC_URI="mirror://gnu/glibc/glibc-${GLIBC_RELEASE_VER}.tar.bz2 mirror://gnu/glibc/glibc-ports-${GLIBC_PORTS_VER}.tar.bz2 ftp://sources.redhat.com/pub/glibc/snapshots/glibc-ports-${GLIBC_PORTS_VER}.tar.bz2 mirror://gnu/glibc/glibc-libidn-${GLIBC_RELEASE_VER}.tar.bz2" if [[ -n ${BRANCH_UPDATE} ]] ;
