How to tell llamafile to *not* use system wine on a Linux box with wine installed

[ronjouch]

Today I tried simonwillison's llamafile example on 2 machines:

• On my work machine (Debian 12.2, Gnome, Kitty/Fish, no wine installed), it runs flawlessly
• On my home machine (Arch, Gnome, Kitty/Fish, wine installed), it seems to be automatically be detected as a Windows binary, tries to run via wine, and crashes:

If instead of ./llamafile-server-0.1-llava-v1.5-7b-q4 I simply sh ./llamafile-server-0.1-llava-v1.5-7b-q4, things work well.

Is this a known glitch, or a problem with my machine? Can something be done by llamafile packaging / binary build to "de-prioritize" running via wine and prefer running as native Linux? Should README usage suggestion be updated to tell users to sh ./llamafile instead of just ./llamafile ?

This is happening because your system configures binfmt_misc to run MZ executables under WINE. You can fix it by running:

sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf
sudo chmod +x /usr/bin/ape
sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"

Let me know if that doesn't fix things, and I'll reopen this issue.
