Bug 310615 – =dev-db/mysql-5.1.44-r1 fails to compile: Active GCC too old.

• Status: RESOLVED FIXED
• Product: Gentoo/Alt

[Description nietonfir 2010-03-21 21:58:22 UTC]

According to the eclass >mysql-5.0.83 needs at least GCC4.3, but the ebuild says _DEPEND="|| ( >=sys-devel/gcc-4.3 >=sys-devel/gcc-apple-4.2 )"_.

My current gcc-version is: gcc (GCC) 4.2.1 (Apple Inc. build 5574).

After commenting lines 612 - 618 in the mysql.eclass [1], mysql emerges just fine. Any ideas how to solve this one without providing a prefixed eclass? Maybe by adding another method that passes also the name? I don't know where gcc-version is set, but one could add gcc-name [2] and then [3] check for apple(s). ;)

[1]:
#       # Bug #290570 fun. Upstream made us need a fairly new GCC4.
#       if mysql_version_is_at_least "5.0.83" ; then
#               GCC_VER=$(gcc-version)
#               case ${GCC_VER} in
#                       2*|3*|4.0|4.1|4.2) die "Active GCC too old! Must have at least GCC
4.3" ;;
#               esac
#       fi

[2]:
gcc-name () 
{ 
    $(tc-getCC "$@")
}

[3] (no correct bash but you get the meaning):
       # Bug #290570 fun. Upstream made us need a fairly new GCC4.
       if mysql_version_is_at_least "5.0.83" ; then
               GCC_VER=$(gcc-version)
               GCC_NAME=${gcc-name}
               case ${GCC_VER} in
                       2*|3*|4.0|4.1) die "Active GCC too old! Must have at least GCC
4.3" ;;
                       4.2) if [ ${gcc-name} != "*apple"* ]; then
                                die "Active GCC too old"
                            fi ;;
               esac
       fi

Another idea would be to completely remove the check from the eclass because it's already managed through the ebuild DEPEND...

I added this patch instead:
