The value of $host_os, determined by the current config.guess, is:
- On Alpine Linux 3.9: linux-musl
- On Alpine Linux 3.10: linux-gnu
- On Alpine Linux 3.12: linux-musl
The reason is that config.guess tests 'ldd --version'. However, in
Alpine Linux 3.10, /usr/bin/ldd has been replaced with a shell script
that does not understand the --version option:
$ cat /usr/bin/ldd
#!/bin/sh
exec /lib/ld-musl-x86_64.so.1 --list -- "$@"
$ /usr/bin/ldd --version 2>&1
/lib/ld-musl-x86_64.so.1: cannot load --version: No such file or directory
Find attached a proposed fix. More details in
