Thank you very much for your advice. OK, I downloaded that lsm_1_7_15_source.zip and it seems like the calc.h header in it is your problem: It defines sinf (and several others along with it) and it clashes with the system provided header. My suggestion would be removing those wrappers which are already provided by the system headers. Thank you very much. Unfortunately I did not have time to investigate it further last night.
