MoarVM: upgrade and fix some issues

[mojca (Mojca Miklavec)]

• The port needs to be upgraded to the latest Christmas edition.
• The port currently installs a number of libraries that it probably wasn't supposed to (or at least should install them to a different location). We need to find a solution for that (I would like to be able to build it against libraries shipped by MacPorts).
  • ​https://github.com/MoarVM/MoarVM/issues/320
  • ​https://github.com/MoarVM/MoarVM/issues/321
  • ​https://github.com/MoarVM/MoarVM/issues/322
• Due to that the port should conflict with libtommath and others (libuv doesn't directly conflict, but we get a build failure if it's installed for example).
• We might want to explore the options for LuaJIT
• I would like to understand what the comment about perl in the Portfile means.
• It would be nice to enable the test suite with test.run yes.
• May I co-maintain the port (and also make the port openmaintainer)?

Available configurations:

• --has-libtommath
• --has-sha
• --has-libuv
• --has-libatomic_ops
• --has-dynasm
• --has-dyncall
• --has-libffi
• --no-jit - Disable JIT compiler, which is enabled by default to JIT-compile hot frames.
• --lua=path/to/lua/executable - Path to a lua executable. (Used during the build when JIT is enabled).

upgrade MoarVM to 2015.12

[mojca (Mojca Miklavec)]

After some discussion on IRC, changes committed in r143944.

We were asked to help improve the README at ​https://github.com/MoarVM/MoarVM/tree/master/ports/macports

We could potentially keep the ticket open until we figure out what to do with conflicting libraries.

Initial attempt for nqp

[mojca (Mojca Miklavec)]

Ignore the latest upload of nqp and check #50154 instead.

[mojca (Mojca Miklavec)]

Relevant lines from ./Configure.pl where we might need a change:

if ($args{'has-libtommath'}) {
    $defaults{-thirdparty}->{tom} = undef;
    unshift @{$config{usrlibs}}, 'tommath';
}
else {
    $config{cincludes} .= ' ' . $defaults{ccinc} . '3rdparty/libtommath';
    $config{install}   .= "\t\$(MKPATH) \$(DESTDIR)\$(PREFIX)/include/libtommath\n"
                        . "\t\$(CP) 3rdparty/libtommath/*.h \$(DESTDIR)\$(PREFIX)/include/libtommath\n";
}

In edda4685/macports-ports:

MoarVM: add dependencies for 3rd party modules

• Add libuv as a dependency rather than conflicting with it. It is now a dependency of CMake, so people probably have it installed.
• Add a dependency on libatomic_ops due to a build failure on 10.7. Closes: #53171
• Add a dependency on dyncall to further reduce the number of conflicts.
• The libtommath package doesn't seem to be compatible.

See: #50153
See: ​https://github.com/MoarVM/MoarVM/issues/321

Not sure why I kept this ticket open, but

configure.args      --has-libffi \
                    --pkgconfig=${prefix}/bin/pkg-config

now works and could be used if needed.

Again, not sure why this ticket is still open. Closing.
