sane-backends +universal build failure: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags

Build log attached.

When building sane-backends on lion, the build fails with the error “:info:build llvm-gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags”.

Building with “-universal” doesn't help me because various other ports are already installed with “+universal” which seems to get merged in. I'd rather not have to ununiversalise all the dependent ports (of which there are many!), but have this port fixed to work universal!

Interesting; I have no problem installing it universal on Snow Leopard.

Are you sure you're actually requesting the universal variant? It does not look like you are, because your log shows the *FLAGS environment variables at configure time only contain -arch x86_64. It's not until later that -arch i386 appears in the log, and the perl include path appears at that time as well, so this is probably because of bug #24779. So clean and try again, actually specifying the universal variant.

sudo port clean sane-backends
sudo port install sane-backends +universal

Thanks for that, you're right, cleaning and specifying +universal worked fine. So in fact this problem arises when using the default variant, not the universal one! (I came across it when doing a port upgrade outdated, not a specific install of this port…) Could well be the problem you describe - so can probably just close this as not-a-bug? Or maybe leave open until bug #24779 is fixed to see if that fix fixes this?

Should be fixed along with #24779; reopen if not.
