Cannot build cores using Xcode 6 GM

When running libretro-build-ios.sh, I get the following error:

Has anyone been able to build using the latest Xcode?

[yoshisuga]

The following cores don't compile using Xcode 6:

build_libretro_bsnes
build_libretro_mame078
build_libretro_mame
build_libretro_mupen64

Yup, fails for me too on Xcode 6.0.1 with the same error. Code at fault is in libco/armeabi.c. Seems there is an issue with posix_memalign that is active when -DHAVE_POSIX_MEMALIGN is active. Also had to disable: build_libretro_picodrive

[crazyquark]

The only thing I could figure out is that the co_create uses C-linkeage while posix_memalign is probably C++ linked. Not sure these can mix.

Can you retest it now? It should work now.

Hello,

Indeed the libco error is gone(what was the fix? I am having trouble finding the change) However, now the build process fails because of the precompiled build tools that are missing (prec-build folder - for MAME I believe):

Where should I get the prec-build folder?

Errors are: ar -cr obj//libsqlite3.a obj//lib/sqlite3/sqlite3.o mkdir -p obj//build cp -R prec-build/makedep obj//build cp -R prec-build/makemak obj//build cp: cp: cp -R prec-build/file2str obj//build prec-build/makedep: No such file or directory prec-build/makemak: No such file or directory make: * [obj//build/makemak] Error 1 make: * Waiting for unfinished jobs.... make: * [obj//build/makedep] Error 1 cp: prec-build/file2str: No such file or directory make: * [obj//build/file2str] Error 1 Failed to build MAME (iOS) cp: mame_libretro_ios.dylib: No such file or directory

Disabling mame in the build script I am left with a different error, related to picodrive:

[crazyquark]

The following cores still fail to compile with Xcode 6: (I had to disable them)

build_libretro_mame078 build_libretro_mame

build_libretro_picodrive build_libretro_mupen64
