[New-bugs-announce] [issue26317] Build Problem with GCC + Macintosh OS X 10.11 El Capitain

[Robert P Fischer]

New submission from Robert P Fischer:

Changes to OS X 10.11 render GCC's Objective-C compiler useless.  However, I want to compile the main part of Python in GCC (because my C++ / Fortran Cython modules use GCC).

I tried to build Python (via MacPorts) using Clang for Objective-C and GCC for C/C++.  The environment upon running ./configure included:

  CC='/Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9'
  CXX='/Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9'
  OBJC='/usr/bin/clang'
  OBJCXX='/usr/bin/clang++'

HOWEVER... the build still tried to use GCC to compile Objective-C, and failed miserably:



:info:destroot /Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9 -pipe -Os -arch x86_64 -Wno-unused-result -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -o FileSettings.o -c ./FileSettings.m
:info:destroot /usr/include/objc/NSObject.h:22:4: error: unknown type name 'instancetype'
:info:destroot  - (instancetype)self;
:info:destroot     ^
...



Log file attached.
