PlatformIO not longer working with MySensors

[fishermans]

Hello,

after some updates MySensors not longer working with MySensors.
Here are the error:

Linking .pioenvs\genericSTM32F103C8\firmware.elf
.pioenvs\genericSTM32F103C8\src\main.cpp.o: In function premain()': main.cpp:(.text.startup._Z7premainv+0x0): multiple definition of premain()'

*** [.pioenvs\genericSTM32F103C8\firmware.elf] Error 1
===================================================== [ERROR] Took 30.84 seconds =====================================================
The terminal process terminated with exit code: 1

I don't know if it is an error from PlatformIO or from MySensors. My other projects without MySensors Library are working fine.

Best regards

Elmar

@fishermans, I would look into this for you but I do not have enough information to be able to reproduce your error.

The error looks a little strange. Please post the contents of your platformio.ini.

As a first hipshot, I would try removing .pioenvs and then compile and upload your blobs.

Hello,

thank you for your help. I remove the .pioenvs folder and get the following messages:

Yesterday I found a solution:

If I change the following line

// #include <MySensors.h>
#include <core/MySensorsCore.h>

then I could compile the code.

Hi Elmar

You probably need to peg the version of MySensors to an older one.

See some examples here:
https://github.com/oneyb/template-mysensors-platformio/blob/master/platformio.ini

Again, please post the contents of your platformio.ini file
Best wishes

[fishermans]

Hello,
oh ok I forgot the platformio.ini

[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduino

lib_extra_dirs = D:\Dropbox\Elektronik\platformio\libraries

lib_deps = https://github.com/mysensors/MySensors.git#development

upload_protocol = stlink

Best regards

Dropping this here for future searchers:

I'm seeing this with the platformio framework-arduinoststm32-maple framework as well.
The problem appears to be multiple definitions of premain() and main(). I suspect one should be marked with the "weak" attribute to allow the other to override as needed. Though the question is which one?
(NOTE: I'm not sure if the Arduino compiler/linker know/care about "weak")

I'm new to the platformio so am having trouble sorting out what is coming from where in order to know who to ask about this. I'm suspecting its the stm32duino folks.

Take a look at this forum comment where I've shown the syntax for the "weak" attribute if interested in going this route.
