[Report] Wiki-Arch toolchain

[StewartBie]

Refer to Wiki - Installation - Arch/Manjaro the AUR package riscv64-unknown-elf-newlib was last updated 2020-03-23 20:29 (UTC) so there are many obstacles to installing this AUR pac. Here are some errors when installing

I wonder whether these package can replace.(WCH MRS toolchain)

This package dedends on the three others mounriver-studio-toolchain-bin Thanks for your reply. ^.^

I'm not sure that I fully understand the original issue but if the problem is getting a working (and maybe more up to date?) RISC-V bare metal toolchain for use on Arch Linux then would the xPack binary toolchain builds be of any use?

• https://xpack-dev-tools.github.io/riscv-none-elf-gcc-xpack/
  • https://xpack-dev-tools.github.io/riscv-none-elf-gcc-xpack/docs/releases/

The only dependency that the Linux builds should have is on a minimum GLIBC version (>= 2.27 right now):

• https://xpack-dev-tools.github.io/riscv-none-elf-gcc-xpack/blog/2024/08/07/riscv-none-elf-gcc-v14-2-0-1-released/#prerequisites

Bear in mind that the xPack toolchain uses a different tool prefix string than the riscv-gnu-toolchain one - riscv-none-elf-* versus riscv64-unknown-elf-* or riscv32-unknown-elf-*:

FWIW I did a quick install of a VirtualBox VM running Arch Linux 2024.08.01, downloaded and extracted the latest xPack RISC-V GCC (14.2.0-1) and using it I was able to compile and link a simple "Hello world" program.

As an Arch user (BTW), I have two suggestions:

1. Report problems with AUR packages to the specific AUR package page. In this case: https://aur.archlinux.org/packages/riscv64-unknown-elf-newlib
2. Do not install AUR packages when there is a better alternative on the official repos. I have the following packages installed and the toolchain works perfect: riscv64-elf-binutils riscv64-elf-gcc riscv64-elf-gdb riscv64-elf-newlib.

[StewartBie]

Thanks for all your replies. My problems are solved.

1. I know that xpack is another standalone toolchain and it works
2. There is a better choice on the official repos riscv64-elf-binutils riscv64-elf-gcc riscv64-elf-gdb riscv64-elf-newlib
3. I'll keep in mind all your seggestions. ^.^

I think it's time to close this issues. Thanks a lot.
