community 2020 : runtime build problems

[NicoPy]

Hi,

I'm experimenting with community 2020, trying to build a runtime. With the command c:\python38\python.exe build_rts.py --output=build/st --bsps-only stm32f429disco I get the following error :

usage: build_rts.py [-h] [-v] [-f] [--rts-src-descriptor RTS_SRC_DESCRIPTOR] [--gen-doc] [-o OUTPUT] [-l] [-b] [--build-flags BUILD_FLAGS]
                    target [target ...]
build_rts.py: error: unrecognized arguments: --bsps-only

Removing --bsp-only option, makes the command work :

install runtime sources for stm32f429disco
runtimes successfully installed in build\st

Next, with the build command : gprbuild -P build\st\zfp-stm32f429disco\runtime_build.gpr -j0 -f, I get the following error :

runtime_build.gpr:12:23: library directory "Z:\ada\runtimes_src\bb-runtimes\build\st\zfp-stm32f429disco\adalib\" does not exist
runtime_build.gpr:13:22: object directory "obj" not found
gprbuild: "build\st\zfp-stm32f429disco\runtime_build.gpr" processing failed

After creating the obj and adalibdirectories manualy, re-running the command succeeds.

edit : gprinstall -P temp/BSPs/<rts_project>.gpr -p -f does not install the runtime at the right place. --prefix option must be specified.

README.md should be updated.

Thank you for the report @NicoPy , we will update the readme.

For missing directory, -p option should be specified to gprbuild instead of creating directories manually.

Next, I tried to use a runtime I've made . Once installed, I can't select it in GPS. GPS does not show it in the Toolchain configuration box (it was working with with Community Editon 2019).

To install my runtime, I do gprinstall -f -p -P build\kinetis\zfp-mk22f51212\runtime_build.gpr --prefix=c:\gnat\2020-arm-elf\arm-eabi\zfp-mk22f51212.

This creates a zfp-mk22f51212 directory in c:\gnat\2020-arm-elf\arm-eabi with the same structure as in other runtimes (in Community Edition 2019 the structure was different).

I have not found any solution for now.

Hello @NicoPy ,

The README is now up to date.

Next, I tried to use a runtime I've made . Once installed, I can't select it in GPS. GPS does not show it in the Toolchain configuration box (it was working with with Community Editon 2019).

This is because the new build script doesn't install in the compiler by default, and doesn't require gprinstall.

You should do:

./build_rts.py --output=c:\gnat\2020-arm-elf\arm-eabi\lib\gnat --build

c:\gnat\2020-arm-elf\arm-eabi

This is not the correct folder for run-time, it should be c:\gnat\2020-arm-elf\arm-eabi\lib\gnat.

Ok.

This is not the correct folder for run-time, it should be c:\gnat\2020-arm-elf\arm-eabi\lib\gnat.

I've discovered this late this afternoon.

Thanks for your support.
