Hello,
I am trying to build a previously made project in the KEIL environment using STM32F373RC. But I am getting the error "ArmClang: Error: unsupported option '--C99'"during the build phase. I am using "Compiler version 6" as ARM Compiler. Can you help with this?
As the (Arm Compiler 5) option -C99 is no more supported with Arm Compiler 6, use this option:
The Arm Compiler for Embedded Migration and Compatibility Guide confirms option -xc
"...Enables the compilation of C99 source code.
-xc
is a positional argument and only affects subsequent
input files on the command line. It is also only required if the
input files do not have the appropriate file extension."
