Dear all, I was trying to compile the regexp example in the MonetDB-extend repo on a Mac OS 10.13, but got an “unknown option” error: $ make cc -fPIC -DPIC -o lib_regexp.so -shared regexp.o -L/usr/local/opt/openssl/lib -L/Users/jennie/scratch/monet-install/Jul2017/debug/lib -L/usr/local/Cellar/pcre/8.41/lib -lmonetdb5 -lbat -lpcre -Wl,-soname -Wl,lib_regexp.so ld: unknown option: -soname clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [lib_regexp.so] Error 1 I looked around a bit. There are many discussions about clang error ld unknown option, but nothing specific for the “-soname” option. Simply remove this option is not an option. Does anyone know how to fix/workaround this? Thanks a lot! Jennie
