Description Marcus Comstedt 2015-11-24 22:46:35 UTC 
The ebuild for dev-cpp/tbb sets the "arch" parameter to the tbb build system
according to MULTILIB_ABI_FLAG only on x86, not on PowerPC.  This causes the
wrong configuration to be autodetected when building 32-bit libraries on a
PPC64 system (specifically, the symbol "_ZN3tbb19task_scheduler_init10initializeEim" is allowed to remain in the library instead of "_ZN3tbb19task_scheduler_init10initializeEij").

Reproducible: Always

Steps to Reproduce:
1. Build tbb for abi_ppc_32 on a 64-bit system
2. Try to link a 32-bit program using the task_scheduler_init class

Actual Results:  
You get an "undefined reference to tbb::task_scheduler_init::initialize(int, unsigned int)'" link error


Expected Results:  
The program should link correctly
