command line – Stderr: permission denied

I hope someone here would help me with this. I am new to Linux and Ubuntu. I am trying to run a test tool made in Linux environment. I followed the instruction to run step by step command. Half way I ran into this stderr permission denied error. No clue how to solve it. Any advice would be much appreciated!

Below are the commands I entered

cd libosdp-conformance
make 2>stderr osdp-tls

Then I got error message:

-bash: stderr: Permission Denied

I tried adding sudo in front of make but it returns with same error.
