Like previously referred here, ___sincos_stret can not be found when compiling a project that uses this symbol using the Xcode5 command line tools.
In the above referenced thread a solution is posted for IOS targets (passing -miphoneos-version-min=5.0 to the compiler), is there a solution for desktop (x64) targets?
It for example happens for me when trying to compile polycode.
Edit 2:
Strangely, after compiling the libraries referenced in the previous error manually, the error now happens to be located in lto.o, which is an internal llvm header itself...
undef: ___sincos_stret
Undefined symbols for architecture x86_64:
"___sincos_stret", referenced from:
_mdct_init in lto.o
_dradfg in lto.o
I'm running OSX 10.9 DP with Xcode 5. This is the link step.
It seems like un- and reinstalling Xcode5 DP and the OSX 10.9 command line tools solved the problem. I guess there was a problem with updating from the previous versions.
