Portaudio won't compile using macports GCC 4.8 (-arch command option unrecognized / bad register name errors)

Question

I use a lot of C++11 features, so I compile my C++ code using macports gcc/g++.

I can't get Portaudio to compile using macports gcc 4.8. Using the stable build (pa_stable_v19_20111121.tgz), running configure with gcc-mp-4.8 as the compiler resuls in:

Using the latest daily build (Apr 5), I get a bunch of "bad register name" errors:

(more bad register name errors follow)

Answer 1

Your bad register message comes from the fact that CFLAGS are containing both -arch i386 and -arch x86_64. The first one is taken into account ... thus error about bad register for all x86_64 specific registers. An easy workaround is to edit the Makefile and remove -arch i386 in CFLAGS and SHARED_FLAGS variables. I am using a GCC 4.7 compiler and note that I had also to remove -Werror flags (error on warnings), because of the following warning:

variable 'err' set but not used [-Werror=unused-but-set-variable]

I am looking right now in how to fix the configure.
