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.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
