fatal error: stm32_def.h: No such file or directory

[heathkit]

Hi there! Really excited to use this library in PlatformIO. However, with a simple project I'm not able to build. Here's my platformio.ini

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
debug_tool = stlink-v2
build_flags = -std=gnu++11 -MMD -DCONFIG_MAPLE_MINI_NO_DISABLE_DEBUG=1 -DSERIAL_USB 
build_unflags = -lc -lstdc++ -lnosys

lib_deps =
  Nanopb
  PacketSerial
  STM32duino FreeRTOS

When I try to build, I get this error while building FreeRTOS

Compiling .pioenvs/bluepill_f103c8/lib823/STM32duino FreeRTOS_ID2093/FreeRTOS/Source/event_groups.o

Hi,
unfortunately, this library is designed to be used with this core:
https://github.com/stm32duino/Arduino_Core_STM32
You use the one from @rogerclarkmelbourne:
https://github.com/rogerclarkmelbourne/Arduino_STM32
Which are not the same.
I know there is a request in platform.io community to support this core:
https://community.platformio.org/t/stm32-nucleo-discovery-boards-for-arduino/3027

Note that there is also a port of FreeRTOS by @victorpv for @rogerclarkmelbourne core:
https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/STM32F1/libraries/FreeRTOS900

[rogerclarkmelbourne]

There is a several version of FreeRTOS bundled as a library in https://github.com/rogerclarkmelbourne/Arduino_STM32, so I"m not sure why @heathkit would try to use this library

See

https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/STM32F1/libraries/FreeRTOS900

@rogerclarkmelbourne probably because this one has just been referenced by Arduino in the Library manager. ;)

[heathkit]

It was recently added to platform.io: http://platformio.org/lib/show/2093/STM32duino%20FreeRTOS

If you start a new STM32 project on PlatformIO and search for a FreeRTOS library, this is what you find. I guess this is more of a platform.io problem than anything. I'm just using the default config - I don't know how I would go about picking a different core.

[rogerclarkmelbourne]

Umm

Platformio always throws up lots of problems :-(

The Platforino guys should really link to their primary sources and the forums for each one of them.

[fpistm]

I don't know how platform IO handle dependencies.
All libraries related to this github organization are for arch stm32.
Those for @rogerclarkmelbourne core (based on leaflabs) are for arch stm32f1 or stm32f4.

@rogerclarkmelbourne it seems platform io automatically import new library published in Ardhuino library manager.

[rogerclarkmelbourne]

@fpistm

This is a platformio issue, if they don't import the right libraries to match the core.

I've never been contacted by the Platformio team.
I don't support Platformio in my core as its too much work. (remember this is not my "day job")
It says explicitly in my Readme.md that its for the Arduino IDE only.

[fpistm]

I know ;)
I've only answered to @heathkit about why this lib do not work as it is not for the same core.
@heathkit I close this issue as unrelated to this library.

[fpistm]

In fact, there is an issue with this library. It should not use internal core header (stm32_def.h) and use standard Arduino.h as entry point.
Up to the core to define properly what the library need.
Here, it's only the cortex M core to use:
ex for STM32F103 based board:
#define __CORTEX_M (0x03U) /*!< Cortex-M Core */

https://github.com/stm32duino/Arduino_Core_STM32 uses the CMSIS which defined it.
