What windows build are you building against?

If it fails due to libintl you're likely missing the libintl headers that the
windows build was built against.

Then, presumably, your include paths don't include the relevant directory?

it is taken from pg_config.exe

On my linux computer, libintl is in /usr/include

On windows C:\Program Files\ PostgreSQL\16\include

So looks so definition

shared_module(
  'orafce',
  orafce_sources,
  include_directories: [includedir_server],
  install: true,
  install_dir: pkglibdir,
  name_prefix: '',
)

can works only on Linux

msvc requires

include_directories: [includedir_server / 'port/win32_msvc', includedir_server / 'port/win32', includedir_server, includedir],

Another prerequisite is using x64 Native tools command line, but still I have problem, because meson badly detects target cpu

look like my problem - I had to use --wipe

now, I am playing with linking issues

with some changes I am able to build orafce on msvc by meson

Hi!

  In other thread
https://www.postgresql.org/message-id/TYVPR01MB1133078C93F9FE432CA466573E40E2%40TYVPR01MB11330.jpnprd01.prod.outlook.com
Kohei Harikae makes good work to clarify meson documentation, especially
regarding additional libraries.

I suppose in your case meson did not found gettext library, libintl.h
from this library.

You can:
1) install gettext, f.e by vcpkg package manager:
vcpkg.exe install gettext:x64-windows
--x-install-root=c:\postgres\gettext

2) You could add gettext .pc file directory to PKG_CONFIG_PATH ( ;
separated list, meson uses configarations in this order
SET
PKG_CONFIG_PATH=c:\postgres\gettext\x64-windows\lib\pkgconfig;%PKG_CONFIG_PATH%
but this file is not created for this library (you can create it by
yourself, but exists other solution - in step 4)
3) make all other steps to run meson, f.e. call "C:\Program
Files\Microsoft Visual
Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64

4) run meson setup with option -Dnls=enabled - it enables national
languages and uses gettext.
And you have to add options for gettext libraries and includes
directories:
meson setup c:\builddir -Dnsl=enabled

-Dextra_include_dirs=c:\postgres\gettext\x64-windows\include,c:\otherlibs\include
  -Dextra_lib_dirs=c:\postgres\gettext\x64-windows\lib,c:\otherlibs\lib
...other options...

extra_include_dirs and extra_lib_dirs are options defined by PostgreSQL.
This options are
comma separated lists of directories, if every value does not contain
comma itself (if contains, it better
to read meson get_options() documentation, it is not easy to explain
shortly meson language syntax).

meson using PKG_CONFIG_PATH detects all library and makes all work with
include and lib paths,
but if library does not have .pc file, you can define paths in options.

If you build with -Dnlas=enabled, you have to be careful with tests.
Tests in this case run
with the default system language, and some tests will fail, as they are
check log files output
and compare it with English answers.

I hope this helps you.
