GnuTLS build fails on macOS Mojave

[kali0ad]

I'm trying to follow the instructions here: ​https://trac.wildfiregames.com/wiki/BuildInstructions#OSX to build the game on my Mac.

The build fails during the ./build-osx-libs.sh -j3 command.

Below is a snippet of the output:

ERROR: GnuTLS build failed

After some Googling, it looks like this could be:

a) an issue with the --enable-shared flag (​https://gitlab.com/gnutls/gnutls/blob/master/INSTALL.md#compilation)

b) an issue with libhogweed.so (​https://stackoverflow.com/questions/9508851/how-to-compile-gnutls)

c) the path to libnettle (​https://lists.gnupg.org/pipermail/gnutls-help/2016-July/004134.html)

d) something else

I also tried installing libnettle outside of 0ad with the directions here: ​http://www.linuxfromscratch.org/blfs/view/8.3-systemd/postlfs/nettle.html but was unable to install it. The configuration command runs fine, but sudo make install results in:

./install-sh -c -d /usr/share/info
f=nettle.info ; \
	[ -f $f ] || f="./$f" ; \
	/usr/bin/install -c -m 644 "$f" /usr/share/info ; \
	if (install-info --version && \
	    install-info --version 2>&1 | sed 1q | grep -i -v debian) >/dev/null 2>&1; then \
	  install-info --info-dir="/usr/share/info" "$f" ; \
	else : ; fi
install: /usr/share/info/nettle.info: Operation not permitted
/usr/share/info/dir: Operation not permitted
make[1]: *** [install-info] Error 1
make: *** [install] Error 2

Anyone else able to build 0ad on a Mac successfully?
