GCC mcu compiler to use for STM32F4

Posted by SyUm75 on 2015-03-16 10:02

Hello openstm32 community,

I’d like to develop and debug C code on mcu STM32F4.

I installed the Eclipse plugin as described in the openstm documentation in this web site.
When I build my project using an “AC6 STM32 MCU gcc” project C/C++,
The build button calls by default the command:

gcc -mthumb -mfloat-abi=soft -g3 -Wall -fmessage-length=0 -ffunction-sections -c -MMD -MP -MF”main/main.d” -MT”main/main.d” -o “main/main.o” “../main/main.c”

gcc output:
gcc: error: unrecognized command line option ‘-mthumb’
gcc: error: unrecognized command line option ‘-mfloat-abi=soft’

gcc is obviously not the compiler for cross compilation and I must have missed something about configuring/installing the compiler. Should I install a compiler by myself ?

Thanks for your help,
Sylvain

Hi Silvain,

Look like the STM32 board configuration in your project has not been applied (missing compiler prefix, core options, symbols...).

Did you select “Retore Default” in the project properties page ? It could explain why many build options has been erased.

I think the easiest way to resolve this problem is to create a new project. If the issue is persistant, contact us again, we will make further investigation (tell us board and the firmware you’ve chosen).

Regards.
Kevin.

Hi,

I restarted from the beginning and could have a proper configuration. My project compiles ok now.

thanks for your help,
