It's definitely a linker error. Some versions of gcc want the arguments to be in a different order and I always forget what's correct. Try:

gcc -Wall -O2 -o benchmark_threaded -pthread -lm -lc -lliquid benchmark_threaded.c

Hi Joseph,

After removing "-o benchmark_threaded", we still have 4 parameters here " -pthread -lm -lc -lliquid", so 16 combinations. I have tried many of them(not all) but it doesnt seem to work, including the one you suggested.

My gcc:

You can also try compiling and linking in separate steps. First generate the unlinked binary object (using the "-c" flag):

gcc -Wall -O2 -c -o benchmark_threaded.o benchmark_threaded.c

Then link the object the object to the libraries:

gcc -o benchmark_threaded -pthread -lm -lc -lliquid benchmark_threaded.o

The second step is where the ordering matters. The ordering of the libraries together doesn't matter (that is, ordering -lm before -lliquid doesn't make any difference).

If the above doesn't work, try:

gcc -o benchmark_threaded benchmark_threaded.o -pthread -lm -lc -lliquid

The second way works!

gcc -Wall -O2 -c -o benchmark_threaded.o benchmark_threaded.c gcc -o benchmark_threaded benchmark_threaded.o -pthread -lm -lc -lliquid

Thank you!
