Cannot build using riscv gcc on Debian

[mateibarbu19]

Hello, I tried to build some examples for a RISC-V architecture on a Debian machine having installed the requirements specified in this repo's description, but ran into a error. However, using a RISC-V compiler from SiFive's GNU Embedded Toolchain — v2020.12.8 works.

$ dpkg -l | grep gcc-riscv64-unknown-elf

Has anybody experienced this issue before?

8.3.0.2019.08+dfsg-1 that 2019 is conspicuously old.

I don't believe we have anyone who uses Debian as their primary distribution, so I don't think we have a sense of which packages are necessary on Debian-proper. If you have a path to a working toolchain / install directions for Debian, I imagine we would appreciate a PR updating the README with directions for Debian. @bradjc might have a better sense of the risc-v packaging.

I still live in a pretty ARM-only universe. All I do is keep building RISC-V off by default, because their toolchain installation is sadly still a mess (which, this unfortunately just continues to serve as evidence of :/ ).

[alistair23]

You are missing a libc, which libtock-c expects.

You can build it yourself, which the README describes, just look for the section If you would rather compile your own newlib-based libc, follow the steps below.

For Debian you should also be able to use picolibc though. You should be able to just install the package https://packages.debian.org/stable/devel/picolibc-riscv64-unknown-elf which includes support for 32-bit RISC-V

[alistair23]

I had a go at updating the documentation to include instructions using Debian. Try following this and let me know how it goes: https://github.com/alistair23/libtock-c/tree/alistair/rv32-support

[bradjc]

Did you run sudo apt install picolibc-riscv64-unknown-elf?

[mateibarbu19]

As I've already mentioned, yes.

$ dpkg -l | grep picolibc-riscv64-unknown-elf
ii  picolibc-riscv64-unknown-elf                  1.5.1-2

[alistair23]

For debugging it's useful to see the command being run, that can be enabled with V=1.

Also, the README in that branch is apparently wrong, you need to use PICOLIBC=1 (I have updated the README)

So the entire command should be:

make PICOLIBC=1 V=1

[alistair23]

#305

[mateibarbu19]

Using your branch and PICOLIBC works.
