Install

Xcode is required.

Download the binary .pkg. It's not signed, so don't double-click on it; instead, right-click on it and Open. Accept the warning. You will be guided through the installation.

Setting PATH

PATH needs to be set to include /opt/gnat-ce-2021/bin at the front:

bash

Insert

export PATH=/opt/gnat-ce-2021/bin:$PATH

in your ~/.bash_profile_common.

zsh

Likewise, but in ~/.zshrc.

See here for helpful information on moving to zsh.

Installing GDB

gdb has to be 'code-signed' (unless you're willing to run it as root!) and under Sierra and later macOS releases there are additional steps that have to be taken.

For El Capitan, see here.

For Sierra, and High Sierra, see here; in the case of High Sierra, the 10.12.1 paragraph refers.

For Mojave, Catalina and Big Sur, see here.

Notes

The software was built using the building-gcc-macos-native scripts at Github, tag gnat-ce-2021.

Include, library paths

As discussed here, Apple have changed the location of system include files and libraries; they used to be copied from the SDKs to the "standard" /usr/include and /usr/lib either automatically or on command. The workround that this distribution includes has the unfortunate side-effect that /usr/local/include and /usr/include/lib are not automatically included in C/C++ compilations and links.

Tool notes

GDB was rebuilt with the new compiler, with an additional patch.

To use the debugger, it must be signed: again, see above.

Distribution

The distribution was prepared using the distributing-gcc project at Github, tag gnat-ce-2021.
