2_ENVIRONMENT.md may need updating

[rogermc2]

2_ENVIRONMENT.md specifies the command :
$ ./build_rts.py --bsps-only --output=build --prefix=arm-eabi/lib/gnat --link stm32f4
However running this command results in:

./build_rts.py --bsps-only --output=build --prefix=arm-eabi/lib/gnat --link stm32f4
usage: build_rts.py [-h] [-v] [-f] [--rts-src-descriptor RTS_SRC_DESCRIPTOR] [--gen-doc] [--compiler COMPILER] [-o OUTPUT] [-l] [-b] [--build-flags BUILD_FLAGS] [--shared]
                    [--profiles PROFILES]
                    target [target ...]
build_rts.py: error: unrecognized arguments: --bsps-only --prefix=arm-eabi/lib/gnat

What should be the correct command?

You are right the command is no longer available as the documentation is unfortunately out of date. Unfortunately there is no single command that fixes the problem as some of the assumptions the documentation makes no longer hold. I have written a #68 (comment) on another issue on how to build a custom runtime. Let me know if that works for you as a workaround.

Many thanks.
Following advice from #68 I ran ./build_rts.py --rts-src-descriptor gnat_rts_sources/lib/gnat/rts-sources.json --build stm32f4 successfully:
runtimes successfully installed in /System/Volumes/Data/Ada_Source/bb-runtimes/install.

My only problem was in learning how to "clone" a fork! For which chatGPT provided the necessary instructions.
Now to try to do a runtime extension.

It's great to hear that you could solve the problem. I'll leave the issue open to keep the out-of-date documentation on our radar. If you happen to run into any runtime-specific problems, let me know!
