stdio cannot build tcp benchmarks

I can build stdio, but when I cd into bench/tcp and run:

cabal new-build --constraint='primitive==0.6.4.0' -w /opt/ghc/8.6.3/bin/ghc

I get the following error:

I have installed libuv1 and libuv1-dev with apt.

Can you tell me what's the version of your libuv1 and libuv1-dev installation?

I think it's 1.0.0:

/usr/lib/x86_64-linux-gnu/libuv.so.1.0.0

I think it's a bit of too old, uv_translate_sys_error is declared public in version 1.10.0. Can you try a newer version of libuv and try again? BTW. Which OS are you using?

Ubuntu 18.04. I guess the libuv in its repo is just outdated.

Strange, I'm running Ubuntu 18.04 too and the repo version is 1.18.0 which is OK. Let me check again.

@andrewthad I have changed the benchmark's cabal file to use stdio as a dependency, you should first install stdio into global or benchmark's sandbox. I have no problem running tcp benchmark in my Ubuntu 18.04 machine, please give me feedbacks if you're still not be able to get it running.
