pthread library error about riscv-glibc HOT 3 CLOSED

pk does not support dynamically linked programs; you must use -static. However, that will not work in this case, either, because pk does not support pthreads. You are better off running Linux than using pk for this purpose.

from riscv-glibc.

So what should I do for running .o file? Can you explain the command used to run on linux?

from riscv-glibc.

You can run the program on user mode qemu. user mode qemu supports dynamically linked programs and pthread. However, sometimes parallel programs fail on user mode qemu and I don't know why. If you have riscv-gnu-toolchain, then "make stamps/build-qemu" will build and install qemu. Or you can get it from qemu.org. Or if you have a recent enough linux distro, you can probably apt/yum/dnf/whatever install it.

Or, you can boot a linux image on system mode qemu, log in, and then compile and run the program natively. This is likely to work better than user mode qemu for parallel programs. I haven't see pthread failures when using system mode qemu.

Or if you have hardware that can boot linux, you can compile and run natively there.
