Cosmopolitan builds binaries that run on all major platforms.
|
||
|
|
You need to compile them on Linux, using any distro you like.
|
||
|
|
Consider setting up Alpine, Debian, or Ubuntu in a VMWare VM.

DETAILS
|
||
|
|
|
||
|
|
Actually Portable Executable assumes stock Linux configuration.
|
||
|
|
Normal behavior is non-ELF files with x bit are run by /bin/sh.
|
||
|
|
Linux lets people globally define arbitrary magic interpreters.
|
||
|
|
Your computer couldve been tuned to run MZ scripts inside WINE.
|
||
|
|
So if you use binfmt_misc you need to explicitly register this.
|
||
|
|
|
||
|
|
WORKAROUND
|
||
|
|
|
||
|
|
sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register"
