Dependency question with cross compile in Linux to Win64

[acwn1976]

Hi all,

I want to cross compile a wxwidgets app in Linux to Windows64 and in Linux I have dependencies like libcurl. I have cross-compiled libcurl but when the meson app checks for dependencies it fails

meson setup --buildtype release --pkg-config-path ${CI_PROJECT_DIR}/curl-${CURL_VERSION}  --cross-file x86_64-w64-mingw64.txt build

Found pkg-config: NO

Run-time dependency libcurl found: NO 
meson.build:7:11: ERROR: Dependency lookup for libcurl with method 'pkgconfig' failed: Pkg-config for machine host machine not found. Giving up.

What do I need to do so that meson uses the correct cross-compiled libcurl ?? How does this suppose to work?

Thank you
Alexander

You need a pkg-config (or is it pkgconfig now? I can't remember, one will give you a deprecation warning) entry in the binaries section of your cross file. Usually thats implemented via a shell wrapper with PKG_CONFIG_LIBDIR set:

#!/usr/bin/env sh

PKG_CONFIG_LIBDIR=... pkg-config $@
