Install error: implicit declaration of function 'clock_gettime' is invalid in C99 #133

Closed OADesigns closed 2 years ago

OADesigns commented 2 years ago

I don't really know any C but am trying to install node-datachannel, and it uses libdatachannel and this, libjuice, as a dependency. This is on an older macOS, 10.10 I'm using as a test server. I'm using npm run build and the error stops the build and the exact error is:

[ 2%] Building C object _deps/libdatachannel-build/deps/libjuice/CMakeFiles/juice-static.dir/src/random.c.o /Users/testserver/Desktop/node-datachannel/build/_deps/libdatachannel-src/deps/libjuice/src/random.c:75:6: warning: implicit declaration of function 'clock_gettime' is invalid in C99 [-Wimplicit-function-declaration] if (clock_gettime(CLOCK_REALTIME, &ts) == 0) ^ /Users/testserver/Desktop/node-datachannel/build/_deps/libdatachannel-src/deps/libjuice/src/random.c:75:20: error: use of undeclared identifier 'CLOCK_REALTIME' if (clock_gettime(CLOCK_REALTIME, &ts) == 0) ^ 1 warning and 1 error generated. make[2]: [_deps/libdatachannel-build/deps/libjuice/CMakeFiles/juice-static.dir/src/random.c.o] Error 1 make[1]: [_deps/libdatachannel-build/deps/libjuice/CMakeFiles/juice-static.dir/all] Error 2 make: *** [all] Error 2 ERR! OMG Process terminated: 2

Am I doing something wrong? Any help or a workaround would be a life saver right now as I have no idea what to do.

The issue comes from macOS 10.10 which lacks the actual function, you need at least macOS 10.12. MacOS 10.10 is very old (it hasn't received security updates for a couple years now), is there a reason to use it?

I added a quick workaround: https://github.com/paullouisageneau/libjuice/pull/135

The fix is released in libjuice v0.9.3, to check it works with node-datachannel you'll need to change GIT_TAG to v0.15 or master here: https://github.com/murat-dogan/node-datachannel/blob/b6ce3bc90903be3160c4188bd094df8bfffe2e0e/CMakeLists.txt#L30

Yes I was using 10.10 because it runs on an older machine that starts to slow down whenever I update it. I appreciate you taking the time to create the workaround and will give it a try and let you know.If I still have issues I will probably have to find something that will install linux as I imagine it would give less headaches. Thank you again.
