 Reporter:  john.ehrlinger@…  |      Owner:  macports-tickets@…
     Type:  defect            |     Status:  new
 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.2.1
 Keywords:  OpenMP            |       Port:  llvm-gcc42
------------------------------+--------------------------------
 This came up while installing an R package that uses the OpenMP framework.
 The package requires autoconf to be installed. Clean install of MacPorts
 with only autoconf with XCode V5.0.1 on OS X 10.8

 Works expected with ./configure with OpenMP support.

 Install the llvm-gcc42 port and configure fails with

 checking for llvm-gcc-4.2 -arch x86_64 -std=gnu99 option to accept ISO
 C89... none needed
 checking for llvm-gcc-4.2 -arch x86_64 -std=gnu99 option to support
 OpenMP... unsupported
 configure: WARNING: OpenMP does NOT appear to be supported on this system.
 configure: creating ./config.status

 The log file indicates:
