Compile Nominatim without cloning osm2pgsql cloned and without PHP installed

[Yamakasi]

Hi,

I want to offload PHP to other PHP servers so I like to compile Nominatim without PHP installed.

Is this possible ?

Also I like to not download osm2pgsql when cloning, I want to have only Nominatim to be compiled.

I assume that sharing the nominatim PHP files between my PHP backends and the Nominatim server(s) is enought to make this work ? Without having ngxin/apache local might be impossible ?

I run into these:

Cloning into 'Nominatim'...
Submodule 'osm2pgsql' (https://github.com/openstreetmap/osm2pgsql.git) registered for path 'osm2pgsql'
Cloning into '/opt/src/Nominatim/osm2pgsql'...

and:

CMake Warning at CMakeLists.txt:69 (message):
  pyosmium-get-changes not found (required for updates)


CMake Error at CMakeLists.txt:88 (message):
  PHP binary not found.  Install php or provide location with
  -DPHP_BIN=/path/php

Hoping that someone can clear this out.

Thanks!

The cmake script defines various parameters to compile and install only parts of Nominatim:

BUILD_IMPORTER - Build everything for importing/updating the database
BUILD_API - Build everything for the API server
BUILD_MODULE - Build PostgreSQL module
BUILD_TESTS - Build test suite
BUILD_DOCS - Build documentation
BUILD_OSM2PGSQL - Build osm2pgsql

You can use those to switch off building parts of Nominatim. If you want to run the API on a different machine, you could switch off everything except BUILD_API. With -DBUILD_OSM2PGSQL=off the osm2pgsql submodule is not necessary. (Word of warning: these switches are rarely used and not well tested, so you might stumble over some bug you might want to report.)

You can ignore the non-fatal warnings about pyosmium.

OK great, thanks for the reply!

You talk about API, I wonder... if I use a PHP library against Nominatim I don't need the PHP processing for that at all on the Nominatim side ? Because that would be awesome!

/edit oops... someone else was loggedin on this browser it seems :) Sorry!
