Build error involving libm #365

Closed dgrisham closed 5 years ago

dgrisham commented 5 years ago

I'm getting an error at the step of linking sndfile-metadata-set:

/usr/bin/ld: CMakeFiles/sndfile-metadata-set.dir/programs/common.c.o: undefined reference to symbol 'round@@GLIBC_2.2.5'
/usr/bin/ld: /usr/lib/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

I've tried adding the -lm in a few places, as per the advice here: https://github.com/NanoComp/libctl/issues/1, but haven't figured it out yet.

Here's more context to the output:

Hey there, what OS and C compiler are you using?

dgrisham commented 5 years ago

@benswift I'm on Arch Linux and using Clang (I ran the build commands again after doing export CC=clang to be sure, and I got the same error):
