Redundant redeclaration of SystemCoreClock

Armandas — Tue, 08 Jun 2021 02:08:31 GMT

I am using a MCUXpresso IDE V11.3.1 to generate board configuration files for MKE16Z series device.

I have enabled extra warnings in my project, among them "-Wredundant-decls". With this option, the compiler produces the following warning in board/clock_config.c:

../../../board/clock_config.c:46:17: error: redundant redeclaration of 'SystemCoreClock' [-Werror=redundant-decls] 46 | extern uint32_t SystemCoreClock; | ^~~~~~~~~~~~~~~ In file included from ../../../lib/NXP_MKE16Z64/devices/MKE16Z4/MKE16Z4.h:137, from ../../../lib/NXP_MKE16Z64/devices/MKE16Z4/fsl_device_registers.h:24, from ../../../lib/NXP_MKE16Z64/devices/MKE16Z4/drivers/fsl_common.h:22, from ../../../board/clock_config.h:9, from ../../../board/clock_config.c:34: ../../../lib/NXP_MKE16Z64/devices/MKE16Z4/system_MKE16Z4.h:90:17: note: previous declaration of 'SystemCoreClock' was here

Since the declaration is already present in system_MKE16Z4.h, the generator should be updated to remove the duplicate declaration.

Hello,

Thank you for reporting the issue. The redundant declaration of SystemCoreClock variable will be removed from the generated code of the clock initialization source code. It will be fixed in a next release.

Best Regards,
