Hello, I want to run coremark for rv32i core in baremetal mode. I changed only the mak file, build-coremark.sh and Makefile. The changes are only the path definitions, the arch, and abi flags. Then it gives an error about size_t in core_portme.mak . I changed the line from typedef unsigned long int size_t; to typedef unsigned int size_t; . However, I am facing an error in the title.
The full part of the output is below. Could you help me to solve it, please?
