If I try to execute a Linux ELF file on FreeBSD what would happen?

It's a stupid question but I'm curious, will BSD recognise the file as
executable?


EDIT: Thank you for the insight guys. I think I will give FreeBSD a
try.

it simply won't run. you'll get what I believe is called an exec
format error or something like that

Got it, thnx.

why not try it yourself instead of asking?

If you enable the Linuxulator and install the particular userland, you
may be able to get a Linux ELF working.

If you have Linux emulation enabled, and have the right support
libraries installed, it'll run.  Otherwise, it'll recognise it as
executable but fail to start it.

Not if you load linux64.ko first :-).   Then you'll likely get a
dynamic link error instead, unless you have the corresponding Linux
.so libraries installed.

well for freebsd yeah, but that's not on others

You can use `brandelf` to run the Linux Elf binary software, so long
as you have the Linux user land installed.

Unbranded Linux binaries won't run.  After you use `brandelf` to brand
them as Linux binaries, they'll run if the Linuxulator is loaded (and
of course all required shared libraries are present).

Indeed I could, but I'm still reluctant to go through the hassle. One
day I will try FreeBSD.

Sure, that's fair.  The question posed specified FreeBSD, though.

The Linux ABI, in spite  of all its limits, works well on netbsd too.

oops my bad, don't know how I didn't see that

No worries!
