arm-none-eabi-g++ showing error in WSL

[Ganesharyal24894]

When I follow the documentation to build pico-examples in WSL it shows below error for some reason. This happens when I run 'make' command after executing 'cmake' command. The C++ compiler is not supposed to be check while building the firmware right? So why is this happening?

CMake Error at /usr/share/cmake-3.22/Modules/CMakeTestCXXCompiler.cmake:62 (message):
  The C++ compiler

    "/usr/bin/arm-none-eabi-g++"

  is not able to compile a simple test program.

  It fails with the following output:

It looks like your build is trying to use the arm-none-eabi-g++ compiler to build pioasm, when it should be using the native g++ compiler, which is very odd. Could you try this again with the new 2.0.0 sdk and see if you get the same issue?

The documentation has also had some major overhauls, so could you confirm what documentation you're following?

I threw my windows laptop that day itself...

@Ganesharyal24894 In that close is it safe to close this issue?

[Ganesharyal24894]

Yeah go ahead. With new SDK I would anyways prefer to use VSCode extension of Pico.
