The mistake was completely on my part, I somehow connected the dots the
wrong way in my head.
The only exceptions (for now) are archivers/zstd and ports-mgmt/synth
which were already picked up by new volunteers in the mean time.
GCC 6.1 was released this week. The Ada Framework in FreeBSD ports has
been based on GCC 5.3 GNAT although GCC 6.x has been supported for awhile
via the ADA_DEFAULT option in make.conf.
Now that GCC 6 has been officially released, switch to it by default.
People can maintain the old foundation by putting "ADA_DEFAULT=5" in
/etc/make.conf.
Libraries built by one GNAT are unusable by another, so almost every Ada
port has been bumped as a result. Noticable exceptions are dns/ironsides
which fails to build on gcc6 (thus USES=ada:5 is set) and cad/ghdl which
needs additional testing as it may require gcc5 on FreeBSD (DragonFly
uses the LLVM backend only).
These are bindings to a Lua library for Ada. The gpr file is written for
the version of Lua that is default on the system that builds the port.
(see Mk/bsd.default-versions.mk)
There is no documentation available, but two examples with sources are
built and installed for illustration.
