Adding xPack arm-gcc toolchain for Python 3 support in GDB #45

Open salkinium opened 1 year ago

The official arm-none-eabi-gdb-py only supports Python 2.7 and only up to GCC10. GCC11 and GCC12 has completely removed Python 2.7 support (since it's EOL) but didn't add Python 3 support, which sucks a little much.

So… I've looked around, and the xPack GNU Arm Embedded GCC seems to be the best alternative: it uses the official source tarball and adds Python 3 support, and builds both x64 and ARM64.

Would you be interested in adding and maintaining a arm-gcc-xpack formula for this?

You can try our simple formula here:

brew install modm-ext/modm/arm-gcc-xpack@12

Hm, the package seems to install an out-of-date SSL certificate into the Python3.11 installation, very weird:

 $ python3 -c 'import ssl; print(ssl.get_default_verify_paths().openssl_cafile)'

 $ brew uninstall arm-gcc-xpack@12

 $ python3 -c 'import ssl; print(ssl.get_default_verify_paths().openssl_cafile)'

I've been looking into xpack myself but never got the time to try it.

I'm happy to review a PR! :)
