As is clearly described in the documentation for this macro, it expects you to use the $CFLAGS for *both* compiling *and* linking. If you do this, then gcc should automatically link -lthread when you pass -pthread during linking. Mea Culpa! I modified my Makefile.ams now according to your suggestion and it works indeed. Sorry for the confusion! I guess this bug can be closed now!

Lennart, can you confirm your situation, and whether using $CFLAGS when linking solves the problem? Thanks, Qingning signature.asc Description: Digital signature

Shuffling the order of the variable acx_pthread_flags so that pthread comes before -pthread fixes the problem for me. But I guess this isn't the whole story, since -pthread is no longer passed when I do that. Probably both -pthread and -lpthread should be defined. Lennart Hi, Many thanks for the bug report. Can you tell us on what platform this problem is spotted? Thanks, Qingning signature.asc Description: Digital signature
