Re: [Discuss-gnuradio] Build 3.5.3 fails linking gr-fcd (undefined reference to `clock_gettime')

Hi Barry - In order to help you out, we (the list) need the OS and build system info. Although buried a bit, 3 clicks from the top-level wiki on gnuradio.org is "Mailing Lists" :: "Reporting Errors" :: "I've done everything above, and I still have a question. How do I ask it?" [1]. I encourage you (and, anyone posting such issues) to read through this section before posting; doing so will provide the greatest chance of you obtaining positive results quickly. - MLD
