[issue26317] Build Problem with GCC + Macintosh OS X 10.11 El Capitain
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 ^ ...

Robert P Fischer added the comment: I'm trying to compile the Objective-C portions of Python (the Python Launcher app) with clang, not GCC. Why does Python insist on using GCC, even when I set the OBJC env variable to clang? That seems to be a problem that the Python project CAN fix.

Robert P Fischer added the comment: > The makefiles use CC throughout and don't look at and OBJC variable. Is > that variable a standard way to specify an ObjC compiler in makefiles? I believe that OBJC and OBJCFLAGS are standard for Autoconf/Automake: https://www.gnu.org/software/automake/manual/html_node/Objective-C-Support.html https://www.gnu.org/software/autoconf/manual/autoconf-2.61/html_node/Output-Variable-Index.html#Output-Variable-Index https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=using%20objective%20c%20with%20autoconf%20automake I wouldn't be opposed to a patch that makes it possible to specify an ObjC > compiler, could you write such a patch? BTW. The patch should also update > the autoconf script (use AC_PROG_OBJC). Sorry, I don't do Autotools --- a software package that came to us directly from the seventh level of Hell. CMake's main claim to fame is it's not as bad. -- ___ Python tracker <http://bugs.python.org/issue26317> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
