Bug ID: 12691
Summary: host-rust build fails
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: eyalroyee at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
Unable to build host-rust (version 1.33.0).
I'm trying to build host-rust on my Ubuntu 18.04 with buildroot on branch
master (commit 35e845700fb15b4ab30678c073300b508db4eb95)
Steps to reproduce are:
1) select host-rust
2) make host-rust
The error is the following:
failed to parse TOML configuration 'config.toml': expected a table key, found a
right bracket at line 15
failed to run:
/home/eyal/buildroot/output/build/host-rust-1.33.0/build/bootstrap/debug/bootstrap
build
It looks like the HOST_RUST_CONFIGURE_CMDS didn't generated a proper .toml
file.
The 15th line in the generated .toml file is of the following format:
echo '[target.$(RUSTC_TARGET_NAME)]';
I guess that should be some sort of validation for that variable before
evaluating it.
Thanks,
Eyal

Hi,
What arch/libc are you using? Only some combinations of those work (I think
only glibc). Check out:

I'm using arm, little endian, cortex a7 for raspberrypi2 and uclibc.
When I tried to use glibc over uclibc the build was successful.

Yes, I think the Makefile does not support any uclibc build, even though it
works. I needed to build Rust to target uclibc and I hardcoded things and it
worked (this on mipsel).
I did something like this:
https://github.com/alexpdp7/retrofw2-rust/blob/master/0010-Hardcode-target-to-mipsel-uclibc-is-built.patch
The thread I linked contains more details. Also in the repo I collected some
other interesting patches (updating Rust to a later version, patching the
mipsel target to support the device I'm targetting, etc.).
I'm adding myself to the cc:, in case the buildroot devs add support for
uclibc...

Hi Eyal, Alex,
As a short therm solution, I suggested a patch that disable host-rust package
when the target architecture is not supported by rust [1].
I'm not sure how upstream rust project is testing/supporting uClibc-ng or musl.
Note: The current rust version available in Buildroot is old, there is a patch
series adding a Cargo package infrastructure and an update to rust 1.40 (1.43.1
is already available).
Feel free to send a followup patch to enable host-rust for uclibc target.

Best regards,
Romain
