I am getting linker errors when using clock_gettime

StackOverflow https://stackoverflow.com/questions/12762391

Question

To use clock_gettime what library do I need to link with? I am getting linker errors that clock_gettime is undefined.

Was it helpful?

Solution

Try linking to librt:

gcc -o myprog myprog.c -lrt

(also note that you have to put the -lrt flag after specifying the myprog.c source file!)
