I'm not sure the man-pages project really concerns itself with non-glibc libc's. Of course you're right that a project that wants to be portable to multiple libc's will need configure tests (or equivalent). But that doesn't mean that a project that aims to document how to use glibc shouldn't tell users how to use it. My suggestion is that the man pages I mentioned above should have languages like clock_gettime and friends already have. That is, from https://www.man7.org/linux/man-pages/man3/clock_gettime.3.html : Link with -lrt (only for glibc versions before 2.17). Or in the current repo: .SH LIBRARY Standard C library .RI ( libc ", " \-lc ), since glibc 2.17 .PP Before glibc 2.17, Real-time library .RI ( librt ", " \-lrt ) (Not sure why one needs to explicitly tell to link with libc (-lc) and thus how this is an improvement over the older version published on the web page (and in most Linux distros man pages), but I digress) -- You may reply to this email to add a comment.
