I am getting linker errors when using clock_gettime

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

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!)
