There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.
Hydra nixpkgs: ?compare=1538299
Marking packages broken isn't as fatal as throwing an exception. In my usecase,
I wanted to build all non-broken packages, that is:
```
nix-build -E 'with import ./.{}; with lib; flip filterAttrs postgresqlPackages (n: v: !v.meta.broken or false)'
```
To get PostGIS going on Darwin:
1. Add libiconv, as is often required.
2. Expand platforms to `platforms.all`.
3. Deal with PostGIS' quirky build system.
PostGIS' configure.ac has the following gem:
AC_MSG_RESULT([------------------------------------------------------------------------])
AC_MSG_RESULT([ WARNING: You have set the --prefix to '$prefix'. But we mostly ])
AC_MSG_RESULT([ ignore the --prefix. For your info, using the values determined from ])
AC_MSG_RESULT([ $PG_CONFIG we will be installing: ])
AC_MSG_RESULT([ * postgis shared library in $PGSQL_LIBDIR ])
AC_MSG_RESULT([ * postgis SQL files in $PGSQL_SHAREDIR/contrib/postgis-$POSTGIS_MAJOR_VERSION.$POSTGIS_MINOR_VERSION ])
AC_MSG_RESULT([ * postgis executables in $PGSQL_BINDIR ])
AC_MSG_RESULT([------------------------------------------------------------------------])
This is suggestive of some assumptions in the build system, which are
revealed when building in Nix on Darwin: the build fails because the
postgres binary cannot be found in the install prefix specified for
postgis; vis.
cc x -bundle_loader $POSTGIS_PREFIX/bin/postgres
This bundle_loader parameter is only available on Darwin, and this
problem doesn't appear to affect Linux systems.
The solution presented here is to symlink the postgres binary where
PostGIS expects it to be, and then remove it after the build completes.
This is needed because some PostgreSQL plugins don't have a bin
directory. If only these plugins are listed in cfg.extraPlugins buildEnv
will turn $out/bin into a symbolic link to ${pg}/bin. Lateron we try to
rm $out/bin/{pg_config,postgres,pg_ctl} which will then fail because
$out/bin will be read-only.
