arm-none-eabi-gcc@9.2.0_1: cannot find -lstdc++_nano

[rubendibattista (Ruben Di Battista)]

I'm trying to cross-compile a project (​https://gitlab.com/rubendibattista/arduinodue-cmake) that normally builds on Ubuntu, and it used to build also with the cross-compiler here on Macports.

cmake -DCMAKE_TOOLCHAIN_FILE=$(realpath ../cmake/Arduino-Toolchain.cmake) -DCMAKE_INSTALL_PREFIX=$(realpath ../install) ..
realpath: /Users/rubendibattista/git/eve/control-system/ArduinoDueCMake/install: No such file or directory

  The C++ compiler

    "/opt/local/bin/arm-none-eabi-g++"

  is not able to compile a simple test program.

  It fails with the following output:

Any idea if it's a problem with the port or a problem with the project?

Both nano.specs and nosys.specs exist in the port and add -lc_nano to the link, however libc_nano.a is not installed by the port.

This is still an issue with arm-none-eabi-gcc 12.2.0 on M1 with MacOS 12.5.1
