Could not open bootloader about bootimage HOT 11 CLOSED

The error occurs here in the code, which means that the bootloader build succeeded, but there is no bootloader output file. I don't know how this could happen.

Which version of bootimage and bootloader are you using and what's your Rust version? And which OS are you on (Windows, Linux, macOS)?

from bootimage.

I am using the latests release to this date, Rust 1.33.0-nightly, on Linux

from bootimage.

Thanks. That's strange, I'm using Linux too and it is also regularly tested on travis CI, but I've never seen this error. Do you use any .cargo/config files or special Rust/Cargo environment variables such as RUSTFLAGS?

from bootimage.

I have a special path environment for Rust target folder, that's all.
But i also did a reset of that and it gave me the same mistake

from bootimage.

This could be the problem. Bootimage performs an uncommon second building step to build the bootloader and it does not handle any target overrides yet. I think the problem is that the bootloader is put to your custom target folder, but bootimage looks for it in the default location.

What option are you using exactly to override the target folder?

from bootimage.

Something like

export $CARGO_TARGET_DIR=/path/to/my/custom/target/dir

from bootimage.

Ok. Could you try wether it works when you don't set the environment variable?

from bootimage.

Yeah, looks like that works...

I wonder why it doesn't work when I simply have that set and simply unset it at runtime

like if I have set
export CARGO_TARGET_DIR=/path/to/my/custom/target/dir
and then
export CARGO_TARGET_DIR=

after that using bootimage don't work.

But it works when I don't set that env at all

from bootimage.

I just opened #26, which should fix the compilation with a set CARGO_TARGET_DIR. Could you try whether this works for you? To install the version from this pull request, run:

cargo install bootimage --git https://github.com/rust-osdev/bootimage.git --branch bootloader_target_dir --debug --force

from bootimage.

Yeap, it worked!!! Nice :3

Perfect, thanks for testing!
