| |
`hostname` may not be present on some systems as it's not mandated by POSIX/SUSv4. This isn't just a theoretical problem: on Arch Linux, `hostname` is provided by `inetutils`, which isn't part of the base distribution.
./scripts/mkcompile_h: line 38: hostname: command not found
Use `uname -n` instead, which is more likely to be available (and mandated by standards).
