|
|
On some devices, GNU make 4.3 fails with 'Function not implemented',
|
|
and the workaround is to compile it with '--disable-posix-spawn'.
|
|
This option will shadow the original make in a really dirty way,
|
|
by overlaying broken gnumake with a fixed version on proot level.
|
|
Please only enable this for a limited time:
|
|
get stuck with a broken build; stop attempting to build something;
|
|
enable the option; nix-on-droid switch, relogin, build,
|
|
disable the option; nix-on-droid switch, relogin.
|
|
|
|
If you leave it on, Nix-store validation will fail,
|
|
repairs will break the working make,
|
|
updates will do bad things. You have been warned.
|
|
|
|
If you find yourself needing that hack, please report details at
|
|
https://github.com/t184256/nix-on-droid/issues/91
|
|
and consider building remotely as an alternative for such devices:
