/usr/bin/ld: libsass/libsass.a(functions.o): undefined reference to symbol 'floor@@GLIBC_2.2.5'
/usr/bin/ld: note: 'floor@@GLIBC_2.2.5' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
Following this helpful suggestion fixes the problem. Just add -lm to the gcc line in the Makefile.
Thanks; I'll explicitly add the -lm if other environments need it (though it builds fine on my test systems).
Shouldn't this be closed? It looks like it's been done.
This appears to be resolved. Closing for now.
