I am using RACON(https://github.com/isovic/racon) to call consensus sequence of a genome.

I get the following error:

terminate called after throwing an instance of 'std::system_error'
what():  Enable multithreading to use std::thread: Operation not permitted
zsh: abort      racon reads.fq mapped.paf contigs.fasta

I have already installed

1. gcc 4.8+ and clang 3.4+
2. cmake 3.2+ to satisfy the Racon requirement.

Is anyone encountering the same problem? What do I have to do?

Thanks.
