I get multiple errors regarding existing symbolic links, e.g.:

==> Starting prepare()... ln: failed to create symbolic link 'isl/isl-0.21': File exists

Adding -f to all ln -s commands in the PKGBUILD fixed the problem for me.

Yeah, that confused me too. The riscv toolchain is a little funny in that way. Upstream recommends you just build the riscv64-unknown-elf-gcc and then compile with -march=rv32i -mabi=ilp32 (or whatever suits your platform).

You can see (or steal from) my experiments with the hifive1 board at

Description says that this supports 32bit RISC-V, but no riscv32-unknown-elf-gcc binary is generated. Am I missing anything?

I assume you mean dtc rather than dct.

That's odd. I don't have dtc installed and it compiles fine for me. Also I don't see why gcc should use the dtc. Devicetrees are used to describe hardware memary map layout, IRQ numbers etc. so u-boot and the linux kernel uses it (although the linux kernel has a version of dtc in-tree). But I don't see why gcc would need that.

How about addingt the dct package (device-tree-compiler) to the dependencies? Otherwise it won't build for me and dct is in the official repositories.
