Diosix fails to build about diosix

[diodesign]

Thanks for the report. I'm a bit confused at the moment because it builds on:

• Fedora 32 with riscv64-linux-gnu-ld version 2.34-2.fc32
• Ubuntu 20.04 with riscv64-linux-gnu-ld version 2.34-6ubuntu1 (build log)

But not on:

• Debian bullseye/sid with riscv64-linux-gnu-ld version 2.35.2
• Debian 10.8 with riscv64-linux-gnu-ld version 2.31.1

@Steinegger: Which OS and version of riscv64-linux-gnu-ld are you using, please?

[Steinegger]

To add to the confusion: I was building it on 20.04.2:

% riscv64-linux-gnu-ld --version
GNU ld (GNU Binutils for Ubuntu) 2.34
[...]
% lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.2 LTS
Release:        20.04
Codename:       focal
% dpkg -l | grep riscv
ii  binutils-riscv64-linux-gnu           2.34-6ubuntu1.1                       amd64        GNU binary utilities, for riscv64-linux-gnu target

I would have tried with the toolchain I built from scratch instead of the one from the package manager but I couldn't find a way to override that part?

[diodesign]

To override the linker paths, you need to edit the .cargo/config files in src/hypervisor and src/services and change the appropriate settings. In the meantime, I've moved away from assembling and linking files via the Mason build script, and instead used the Rust toolchain to handle the assembly and linkage. This work is in the ripmason branch.

I can get this to build on:

• Fedora 32 with riscv64-linux-gnu-ld version 2.34-2.fc32
• Ubuntu 20.04 with riscv64-linux-gnu-ld version 2.34-6ubuntu1.1
• Debian 10.8 with riscv64-linux-gnu-ld version 2.31.1

Though not Debian bullsey/sid with 2.35. And also the boot process doesn't complete, though I'm still working on it. It might be that 2.31 to 2.34 is good. I'd like to find the root cause -- please bear with me.

[diodesign]

@Steinegger Could you please try building the latest development branch (ripmason) and see if works for you with binutils version 2.34-6ubuntu1.1? Eg:

git clone -b ripmason --recurse-submodules https://github.com/diodesign/diosix.git
cd diosix && just

Would be interested to see if that works, and if so, that just leaves 2.35.x to deal with. Thanks!

[Steinegger]

@diodesign I just tested it and it works perfectly with my configuration 👍

[diodesign]

Awesome :) Thanks so much for testing it -- I'm going to keep this issue open for now in case anyone else runs into a binutils clash. It might be a 2.35.x problem.
