I took another look and got it working, after something else I'm using
insisted on installing libpq. It's mostly no-brainer hunks like this:
- dependencies: [frontend_code, libpq],
+ dependencies: [libpq, frontend_code],
For the new src/test/modules/test_oat_hooks/meson.build, I copied what
I'd seen in contrib modules that use libpq:
- kwargs: pg_test_mod_args,
+ kwargs: pg_test_mod_args + {
+ 'dependencies': [libpq] + pg_test_mod_args['dependencies'],
+ }
(I'm still green enough with Meson that I had to look that syntax up:
it's how you replace the values of common keys with the values from
the right hand dict[1], which ain't Pythonesque AFAIK.)
For ecpg and pg_regress, where I got stuck last time, I am still a bit
confused about whether it should go here:
-ecpg_inc = include_directories('.')
+ecpg_inc = [libpq_inc, include_directories('.')]
... or perhaps in intermediate ecpgXXX_inc variables or the final
include_directories directives. In this version I just did that easy
thing and it works for me. But is it the right place?
Likewise for pg_regress_inc, also used by ECPG and isolation tests:
-pg_regress_inc = include_directories('.')
+pg_regress_inc = [libpq_inc, include_directories('.')]
