BuildSources() not work from post : script.py

[Wiz-IO]

I want to add and compile code from not compiled framework folder
but BuildSources() not work from POST:SCRIPT.PY

as example:
https://github.com/Wiz-IO/TEST/blob/main/PICO-LWIP-APP/extra_script.py

pre:scrypt.py
BuildSources() work
BuildLibrary() work

post:scrypt.py
BuildLibrary() work
BuildSources() not work … Is it a BUG? or I make any wrong...

Hi Georgi,

This is a feature, not a bug. The inline source files are handled at the BuildProgram step which you call in your platformio/main.py

So, any calling of BuildSourceslater does not have any effect. We will inform the user about this issue.

Hi Ivan, thanks for the answer

my thought was: add_module( src folder ) from ini file ... CMAKE uses similar practices
some code is not compiled by main builder, but exist in framework
example:
lwip is compiled as basic, without apps ... http, tftp etc
and I wanted to add them from INI with POST script
for now I found a way with PRE script - I had uninitialized variables

...
Building in release mode
-- EXECUTE POST-SCRIPT.PY --
-- FROM PRE-SCRIPT - BuildSources() -- Compiling WORK
-- FROM MAIN BUILDER --
Compiling .pio\build\...any code...
Compiling .pio\build\any-src\main.o
-- FROM POST-SCRIPT - BuildSources() -- Would be great feature <<<----------
-- FROM POST-SCRIPT - BuildLibrary() -- Compiling WORK
Linking .pio\build\raspberry-pi-pico\APPLICATION.elf
...

you can close issue if not important

I've just added a warning message. Please use BuildLibrary in this case.

BTW in doc
https://docs.platformio.org/en/latest/scripting/actions.html

need more info about action target( trigers )
env.AddPreAction(TRIGER", before)
env.AddPostAction(TRIGER, after)

maybe exist: before_main_build, after_main_build

[ivankravets]

Pre/Post action accepts a taget (or list of targets) as a first argument. Target can be a physical path, a SCons node, or virtual alias.

as idea / info

I make experiment with add "modules" ( not compiled codes, existing in framework ) - makefile style

as example:
https://github.com/Wiz-IO/framework-wizio-pico/tree/main/SDK/lib/at_tok

at_tok is not compiled from my builder by default and I add this module with project ini
board_build.modules = $FRAMEWORK_DIR/SDK/lib/at_tok

the "module" can be existing code in framework or
can be internal or external library ... lib_deps etc
can be compiled "on request"

my add modules function ...
