platformio
Build flags -include ... does not update dependency tree
Configuration
Operating system:
Any
PlatformIO Version (platformio --version):
PlatformIO Core, version 6.1.7a3
Description of problem
-include foo.h, -include bar.h specified in build_flags / build_src_flags does not create a direct dependency on the resulting program like #include in the source does
Steps to Reproduce
Given the project structure
> tree
.
├── platformio.ini
└── src
├── main.cpp
└── vendor
└── custom.h
3 directories, 3 files
platformio.ini
[env:native]
platform = native
build_src_flags = -include src/vendor/custom.h
src/main.cpp
#ifndef FOO
#warning "default value"
#endif
int main() {
}
src/vendor/custom.h
#define FOO

Expected Results
Program should rebuild when include file is modified
Additional info
https://github.com/SCons/scons/issues/3064 Upstream seems to have this on hold because of PCH (aka precompiled headers) support, but idk if it is relevant here edit: and, order matters
At last one instance of -include in PIO documentation
https://docs.platformio.org/en/stable/platforms/espressif8266.html
(and umm_malloc_cfg.h happens to be tracked from a different file anyway, so dependency is added through other means)
Ehm, shouldn't that be -I?
build_src_flags = -Isrc/vendor/custom.h
I get "include file not found" when I change from -I to -include.
Nope, this meant to include a specific file. Relative path meant to originate from $PROJECT_DIR i.e. where platformio.ini is
https://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html#index-include
Im having almost the same issues.
ihave tried serval different include paths in platforio.ini but none seem to work.
build_flags = I-include I-C:\Users\bucko\OneDrive\aElectronics\Projects\BuckosLearning-PH7\include I-C:\Users\bucko\OneDrive\aElectronics\Projects\BuckosLearning-PH7\include\blProjConfig_PH7.h
