board.h missing extern C guard

aberger — Wed, 17 Jul 2024 18:23:11 GMT

This is a bug report. I am using SDK_2.16.000 for the MCXA153. When I use the "Create a new C/C++ project" wizard in MCUXpresso and create a new C++ project, the generated code fails to build because of

undefined reference to `BOARD_InitDebugConsole()'

This is because board.h is missing the extern C guard, which can be fixed as follows:

#ifdef __cplusplus extern "C" { #endif void BOARD_InitDebugConsole(void); #ifdef __cplusplus } #endif

More that a year after you've made a promise, the bug is still there when creating a C++ project in a fresh installation (december, 2025):

undefined reference to `BOARD_InitDebugConsole()'

Does anyone at NXP is taking care of its customers?
