#24923: RFE: Allow atlas to build universal -----------------------------------+---------------------------------------- Reporter: mcalhoun@… | Owner: jameskyle@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.2 Keywords: atlas universal | Port: atlas -----------------------------------+---------------------------------------- Comment(by mcalhoun@…): Replying to [comment:7 vince@…]:
Ok, I am still puzzled that you can compile i386/x86_64 code without having the proper libs. For example, libptf77blas has a dependency to libgfortran, which is not universal unless you build it with --enable- multilib. Yet, I might be wrong. The muniversal PortGroup basically performs the configure, build, destroot, and test phases twice.[[BR]] The first time, -m32 is passed to the fortran compiler to build i386 or ppc libraries.[[BR]] The second time, -m64 is passed to build x86_64 or ppc64 libraries.[[BR]] After the destroot phase, the muniversal PortGroup merges the two installations using, among other things, lipo to form a universal installation.
