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?

Hey kali0ad. Thanks for reporting this. It is a duplicate of #5453 so I'm closing this ticket since #5453 is earlier.

Can you try ​https://trac.wildfiregames.com/ticket/5453#comment:7 ?

Hi Kali0ad,

Yeah, I could build all in osx Mojave. could you add the log please, looks like that something was wrong when building nettle-3.4. I Im guessing because "Libnettle 3.1 was not found."

In 22455:

Fixes GnuTLS build on macOS.
Fixes macOS linker warning "PIE disabled absolute - addressing not allowed".

Updates nettle to 3.5.1, GnuTLS to 3.6.8, gloox to 1.0.22.
Disables TCP fast open feature of GnuTLS (requires 10.11, no SDK build support).
Fixes GnuTLS detection of GMP by adding it to LIBS flag.
Disables getaddrinfo on gloox 1.0.22. Lobby connections failed during server hostname resolution.
Adds --with-pic to GMP build to force consistent PIC usage.
Adds -N flag to patch commands to avoid reapplying them.
Removes unneeded build flags.
Documents --enable-fat configure flag: GMP and nettle detect CPU-specific features, fat binaries let us build and run them on different CPUs (see D1772).

Fixes #5453, 5489. Refs #5481.
