question : how to modify the GCC tools ? #7

Closed fred-r closed 3 years ago

fred-r commented 3 years ago

Hi,

I can see in GCC.9.2.1.mak the following tools definitions:

############ DO NOT EDIT BELOW ########### AS:=$(TOOLCHAIN_ROOT)/$(PREFIX)as CC:=$(TOOLCHAIN_ROOT)/$(PREFIX)gcc CXX:=$(TOOLCHAIN_ROOT)/$(PREFIX)g++ LD:=$(TOOLCHAIN_ROOT)/$(PREFIX)gcc AR:=$(TOOLCHAIN_ROOT)/$(PREFIX)ar OC:=$(TOOLCHAIN_ROOT)/$(PREFIX)objcopy

For assembler, the tool to be used is arm-none-eabi-as. What if I want to use arm-none-eabi-gcc even for assembler files so that I can use more features and directives like "-x assembler-with-cpp" ?

Thanks & Regards, Fred

Hi Fred,

If you want to customize the configuration file (GCC.9.2.1.mak in this case) without touching the original files, just copy it into the project directory and then apply any change that you may be interested, for example changing 'as' by 'gcc'. Toolchain configuration files in the project directory have precedence over files in the $CMSIS_COMPILER_ROOT directory.

Best regards Daniel
