@SlimSnow See https://github.com/gaffe23/linux-inject#caveat-about-ptrace. You may need to change your OS's setting. Otherwise run injector with root privilege.

If you run it on ubuntu in docker, see https://stackoverflow.com/questions/42029834/gdb-in-docker-container-returns-ptrace-operation-not-permitted.

There are many possible reasons for a dlopen error.
