"gcc47 +universal" not universal on 10.8

Reported by: michaelld (Michael Dickens) Owned by: mww@…
Priority: Normal Milestone:
Component: ports Version: 2.1.3
Keywords: Cc: larryv (Lawrence Velázquez)
Port: gcc47 gcc46


My system is a MacBook Pro 2011 running 10.8 latest, with Xcode latest and MacPorts latest from SVN trunk. I'm actually trying to install "arpack +universal", and it is erroring out during configure (i386) with:

ld: warning: ignoring file /opt/local/lib/gcc47/libquadmath.dylib, file was built for unsupported file format [] which is not the architecture being linked (i386)

so, investigating further

lipo -info /opt/local/lib/gcc47/libquadmath.dylib

returns "Non-fat file: /opt/local/lib/gcc47/libquadmath.dylib is architecture: x86_64" and

port provides /opt/local/lib/gcc47/libquadmath.dylib

returns "gcc47".

port installed gcc47

returns "gcc47 @4.7.3_0+universal (active)". Some of the libraries in /opt/local/lib/gcc47/lib*.dylib are +universal; all are owned by gcc47.

The above is also true for the gcc46 port; I have not tested other gccXY ports.

The i386 libraries are located in /opt/local/lib/gcc47/i386; I think this is the normal state of affairs for a multilib GCC installation. Maybe the configure phase has to pass -m32 to correctly find the 32-bit libraries?

Ah; I see. That leads me back to the arpack configure script, which does seem to be mixing and matching -m32 and -m64, when it should be using the former only for this configure. I'll file another ticket for that issue. Thanks for the quick reply!

So, if i386 libraries are located in /opt/local/lib/gcc47/i386, why are the x86_64 libraries in /opt/local/lib/gcc47 and not /opt/local/lib/gcc47/x86_64? Are these libraries the "default" when no -mXX is supplied?
