system info

root@pve:~/rom-parser# pveversion pve-manager/7.4-3/9002ab8a (running kernel: 5.15.102-1-pve)

root@pve:~/rom-parser# gcc --version gcc (Debian 8.3.0-6) 8.3.0

how

When I ran the make command, I reported an error. The fcntl.h file could not be found, but my gcc has been installed. Do I need to install anything else?

I tried to install build-essential and still reported an error.

root@pve:~/rom-parser# apt-get  install  build-essential

@rickzuo, your libc6-dev dependency is broken. That's an issue of your Proxmox host, I guess.

You should fix the dependencies. Maybe apt update && apt upgrade would do?
