bun build --compile fails with EACCESS trying to write output

[humphd]

What version of Bun is running?

1.0.15

What platform is your computer?

Linux 6.4.16-linuxkit aarch64 unknown (Linux Dev Contianer on MacOS))

What steps can reproduce the bug?

1. Create a file, file.ts: console.log('hello world');
2. Create an executable: bun build file.ts --compile --outfile ./file

What is the expected behavior?

I'd expect to have an executable created

What do you see instead?

 [13ms]  bundle  1 modules
error: failed to open temporary file to copy bun into
EACCES: Permission denied (open())

Additional information

The two calls that are failing in this strace are interesting, specifically:

[pid 19234] openat(AT_FDCWD, ".179e939cefeff7f3-00000000.bun-build", O_RDWR|O_CREAT|O_CLOEXEC, 000) = -1 EACCES (Permission denied)
[pid 19234] openat(AT_FDCWD, "/tmp.179e939cefeff7f3-00000000.bun-build", O_RDWR|O_CREAT|O_CLOEXEC, 000) = -1 EACCES (Permission denied)

I'm not clear why it can't write to . (I have permissions to do it), but should the second not be /tmp/.179e939cefeff7f3-00000000.bun-build (trying to write to the root)?

I noticed this was also fixed for https://github.com/oven-sh/bun/issues/2944 in https://github.com/oven-sh/bun/commit/5bec0252a0223e45571f56dc49c240366df99852

seems bun somehow created a corrupted file, maybe due to linuxkit

the fallback run it creates the file it is missing a / in the path. i can open a fix for that but im not sure about the first EACCES

[jabnakar]

dang this is happening in Windows too , very similar . I used ProcMon to trace and it shows these same folder/files. one difference is the error is "ENOENT"

[paperdave]

note that windows does not support --compile right now, though this bug might be shared.

[jabnakar]

yes i do note that , its not working on both Windows 11 and WSL(Ubuntu), its working on MacOS(Hackintosh). All on the same machine
