How do I do a cross compiling for raspberry pi 3 (arm) from WSL 2

[VinceGHER]

Hello,
I would like to configure vcpkg to do cross-compiling on a raspberry pi 3 (arm) from WSL2.
I use cmake to build my cpp project.
I need to have the cpp 20 standard.

Could you tell me what step I have to follow in order to do this?

ps: I'm new to vcpkg.

Thank you !

You can use VCPKG according to the documentation: https://github.com/microsoft/vcpkg#quick-start-unix, if you have any question when using port, you can comment here.

Hello,
I'm getting this error

-- Using community triplet arm-linux. This triplet configuration is not guaranteed to succeed.

CMake Warning at ports/outcome/portfile.cmake:18 (message):
Outcome depends on QuickCppLib which uses the vcpkg versions of gsl-lite
and byte-lite, rather than the versions tested by QuickCppLib's and
Outcome's CI. It is not guaranteed to work with other versions, with
failures experienced in the past up-to-and-including runtime crashes. See
the warning message from QuickCppLib for how you can pin the versions of
those dependencies in your manifest file to those with which QuickCppLib
was tested. Do not report issues to upstream without first pinning the
versions as QuickCppLib was tested against.

"quickcpplib/config.hpp" from port ned14-internal-quickcpplib, it is dependency of outcome. You could check if it install correct.
