PROCESSOR-SDK-J784S4: Linker error: Undefined symbol - vApplicationLoadHook

Attiya Mahmood

Tool/software:

I have a PDK-based application built on PSDK RTOS (ti-processor-sdk-rtos-j784s4-evm-09_02_00_05) for the C7 DSP core, containing both C and C++ files. In my build command, I have set CPLUSPLUS_BUILD=yes and BUILD_PROFILE=debug.

My build command is as follows:

make -s BOARD=board CORE=c7x_2 BUILD_PROFILE=debug CPLUSPLUS_BUILD=yes app_test_clean app_test

However, I’m encountering a linker error for the undefined symbol vApplicationLoadHook in ti.kernel.freertos.ae71<port.oe71>.

If I choose BUILD_PROFILE=release, it works all fine.

Can you please guide how to resolve this error?

Regards,

Attiya

Hi Attiya,

Can you provide the build output when you run the following command without the "-s" option so I can see what flags the compiler is picking up?

Hi Asha,

In rules_71.mk, we can see that if we enable CPLUSPLUS_BUILD macro then it is 'fg' compile mode. I do see fg compile mode for both C and CPP files.

Here are the logs for .c and .cpp file

I removed some of the include paths from the log to simplify it little bit but all the compiler flags are intact in the log.

Here is the rules_71.mk that I updated little bit to support macros for cpp files

Hi Attiya,

Can you provide the full logs in this case you mention?
