[question] Cross Building Mac (CLion) and Raspberry Pico #9337

Open jBernavaPrah opened 3 years ago

jBernavaPrah commented 3 years ago

Good morning,

What is the correct profile to use to compile from mac (CLion) to Raspberry PICO?

I have already read and reread the examples from cross building but I'm not able to compile! :(

Thanks a lot!!, JBP

PS: This is my current profile:

toolchain=/usr/local/bin/arm-none-eabi-gcc

[settings]
os_build=Macos
arch_build=x86_64

os=Linux
arch=armv6
compiler=apple-clang

compiler.version=12.0
compiler.libcxx=libc++
build_type=Release

[options]
[build_requires]
[env]
CONAN_CMAKE_FIND_ROOT_PATH=$toolchain
CONAN_CMAKE_SYSROOT=$toolchain

And the error that I receive is:

Hi @jBernavaPrah

It would be great to do it with a known recipe, to be able to reproduce on our side. This "hello world" example, can be easily created with conan new command.

A couple of notes. Depending on the stability constraints, it might be better to use modern Conan features:

jBernavaPrah commented 3 years ago

Thanks for your information. Unfortunately, I don't have enough knowledge to create a working recept.

But I can give you a working project for Raspberry pico (super simple) that compiles and work with standard Mac - Clion settings. This project uses the "SDK C++" from Raspberry Pico.

From my limited knowledge of C++ and compilers, what I think is missing to Conan (based on my project) is all configurations that pico_sdk_init.cmake (included by pico_sdk_import.cmake) automatically add to the compiler.

Therefore I think I have two possibilities:

  1. Tell to conan to use also pico_sdk_import.cmake. I have already tried adding on the profile file on the [conf] section the tools.cmake.cmaketoolchain:user_toolchain=$path/pico_sdk_import.cmake but the output of thee command conan install . --build=missing is not changing.
  2. Download only the sources, include them in projects and leave the "pico SDK" to compile it. This, in your opinion, is possible with Conan?
