Linker error with version 2.7.1 for STM32 Nucleo F446RE #2244
Description
Activity
Hi @npalix
First happy new year.There is no error on my side to build (and link) for the Nucleo F446RE. Moreover, the issue you point will simply impact all target which is not the case.
So you probably have an issue on your environment but you do not provide any information as requested by the issue template.Describe the bug
While compiling for any board the Blink example, I got the following error :arm-none-eabi-g++: warning: {compiler.optimization_flags}: linker input file unused because linking not done arm-none-eabi-g++: error: {compiler.optimization_flags}: linker input file not found: No such file or directoryThe issue seems to come from the platform file.

Line 22 in 2c45eba
Setting the line to
compiler.optimization_flags={build.flags.optimize}fixes the issue.To Reproduce
- Install following the instruction of https://github.com/stm32duino/Arduino_Core_STM32/wiki/Getting-Started
- Load the Blink example
- Compile
Expected behavior
Build binary for the current boardScreenshots
Desktop (please complete the following information):
- OS: Linux
- Arduino IDE version: 1.8.19
- STM32 core version: 2.7.1
- Tools menu settings if not the default: default values
Board (please complete the following information):
- Name: Nucleo F449RE
Additional context
I tried to remove and reinstall STM32Core.As stated not reproduced:
Your logs seems weird because the arm none eabi binary has no full path.
Unfortunately, I can't help on this, maybe an Arduino IDE issue, you should try to remove all cache files and start from fresh install.The path is right with verbose mode (same place as in your screenshot). But it isn't prepended for warning/error messages (I guess g++ behavior).
Can you provide information on how the flag is setup ?
It sounds odd for me to define it by itself and there is an experimental warning the line before.
compiler.optimization_flags={compiler.optimization_flags}My understanding is that the "{compiler.optimization_flags}" is not properly expanded and g++ interpretes it as a filename.
Moreover, the "optimize" value (-Ox) doesn't show up in the compilation command.
Working fine with Arduino IDE 2.0.3.

compiler.optimization_flags={compiler.optimization_flags}@npalix You are right, the line is not correct. I've made a fix even if I can't reproduced (don't know why). This change make sense.
Thanks for your support.If you are able to test.
Note for the Arduino IDE 2.x, the impacted line is not used as only those one are used:
