Cannot find -lrt and -lpthread during make build with "gcc-arm-none-eabi-10.3-2021.10" about coremark-pro

[petertorelli]

rt is the POSIX realitime library (time functions), and pthread is the POSIX threading library. Neither of those come with the GCC Arm toolchain distribution. You will need to implement your own timing, most likely using a variant of SysTick from the BSP for your processor. As for threading, compile in single-thread mode: -DUSE_NATIVE_PTHREAD=0 -DUSE_SINGLE_CONTEXT=1, and remove those options from your makefile.

[sunildogra1710]

As you suggested i used DUSE_NATIVE_PTHREAD=0 -DUSE_SINGLE_CONTEXT=1 and remove rt and pthread option from gcc64.mak.

For everything except the three th_/al_ functions, this is expected behavior. You are compiling a linux program on a baremetal compiler. arm-none-eabi does not have operating system support built in, which is why _link_r, _lseek, _exit, abort are not defined: those are part of the linux library. If you had used arm-linux-eabi then it would have compiled. This is unrelated to the benchmark. Here is a good explanation of the three components in the toolchain name.

Closing this since there has been no follow up.
