It comes from the following in Services.pm:
sub gcc_selected {
# this should work anywhere we support, really
if (-l '/usr/bin/gcc') {
my $link = readlink('/usr/bin/gcc');
if ($link =~ /gcc-(\d+\.\d+)/) {
return $1;
} else {
print STDERR "WARNING: /usr/bin/gcc is not a symlink!";
}
}
return 0;
}
There are two problems here:
1) [minor] The "print STDERR ..." item seems to be the wrong scope.
The inner else block should only be reached if /usr/bin/gcc _is_ a
symlink but to something that doesn't match the pattern. This function
got modified a lot after we stopped supporting 10.4--probably my fault here.
2) Xcode 5 introduces a change in behavior in that /usr/bin/gcc is no
longer a symlink.
I don't know how necessary this test actually is--it's a leftover from
the period when folks needed to use "gcc_select" to switch the default
compiler.
