From 462ea170b1410d7916a25ffa6d27dc45284db7e3 Mon Sep 17 00:00:00 2001 From: Tristan Partin Date: Wed, 17 May 2023 10:36:52 -0500 Subject: [PATCH v1 2/7] Add Meson override for libpq Meson has the ability to do transparent overrides when projects are used as subprojects. For instance, say I am building a Postgres extension. I can define Postgres to be a subproject of my extension given the following wrap file: [wrap-git] url = https://git.postgresql.org/git/postgresql.git revision = master depth = 1 [provide] dependency_names = libpq Then in my extension (root project), I can have the following line snippet: libpq = dependency('libpq') This will tell Meson to transparently compile libpq prior to it compiling my extension (because I depend on libpq) if libpq isn't found on the host system. --- src/interfaces/libpq/meson.build | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/interfaces/libpq/meson.build b/src/interfaces/libpq/meson.build index 80e6a15adf..6d18970e81 100644 --- a/src/interfaces/libpq/meson.build +++ b/src/interfaces/libpq/meson.build @@ -84,6 +84,8 @@ libpq = declare_dependency( include_directories: [include_directories('.')] ) +meson.override_dependency('libpq', libpq) + pkgconfig.generate( name: 'libpq', description: 'PostgreSQL libpq library', -- Tristan Partin Neon (https://neon.tech)
