error: RenameAcrossMountPoints about bkg

[theseyan]

Are /tmp and coding/bun-kai/test on different mount points/filesystems?

Edit: I can reproduce the issue, it indeed happens because bkg writes to a temporary file in /tmp while compiling, and it fails to move the file if the output path is in a different filesystem.

[theseyan]

Fixed! Thanks for reporting 👍
I've updated the release assets for v0.0.4, please reinstall and see if it fixes the issue.

[theseyan]

That happens because bkg expects the entrypoint of the application to be index.js (js) by default when bkg.config.json is absent.

A quick workaround is create a bkg.config.json in the project root and set the entry key to index.ts.

This is stupid though, I'll probably add index.ts to default entrypoints 👍

The empty output of cat /proc/cpuinfo | grep -o avx2 means your CPU doesn't support AVX2.
Can you try running bkg with --baseline flag and see if it changes anything?

It solved the error.

Thanks for responding to this issue 🙏

Yup, that's the the problem.

bkg ./ -o /tmp/test

Now it's compiled successfully, but now I get another error :

[oggnimodd]

I've added bkg.config.json, this is what i get :

[theseyan]

I can't seem to be able to reproduce this.

Can you zip up the test folder and upload it so I can have a look?

[oggnimodd]

It's just the default project that is generated with bun init.

https://github.com/dominggo1999/bkg-error-reproduction

even if there is only index.js file it still gives the error

[theseyan]

Looks like the embedded Bun runtime is crashing.
What happens if you run:

/tmp/.test_runtime_1058350503/bkg_bun /tmp/.test_runtime_1058350503/index.js

Does it crash or work correctly?
Also, what is the output of cat /proc/cpuinfo | grep -o avx2?

[oggnimodd]

there is no .test_runtime_1058350503/bkg_bun & .test_runtime_1058350503/index.js in /tmp

[theseyan]

Glad to see this issue solved!

bkg should really check for the support of AVX2 instructions at compile time to make this less confusing; you can be sure to see that in the next release.
