#44871: Building R-3.1.1 on a PPC requires using a compiler that can properly
handle ObjectiveC code

 Reporter:  drjesacco@…  |      Owner:  macports-tickets@…
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.3.1
 Keywords:  PPC          |       Port:  R
-------------------------+--------------------------------
 R-3.1.1, with default variants,  builds on a PPC provided: (1) the Apple
 compiler is used for compiling ObjectiveC code,  and (2) the gcc48 suite
 of compilers is used for everything else:

      sudo port install R configure.compiler=macports-gcc-4.8
 configure.objc=/usr/bin/gcc-4.2

 The Apple compiler is necessary to properly compile the one .m file

      ./src/library/grDevices/src/qdCocoa.m

 If gcc-mp-4.8 is used instead, the quartz graphic device will fail to
 launch, causing R to exit because of an error.
