can I ask if there is a difference between official Arch repo package riscv64-elf-gcc and this package. gcc has only riscv elf and riscv linux project. So I assume it is just a naming thing as it is given in the package build. Most examples uses riscv64-unknown-elf-gcc as executable name tough. Is that why ? Or this package has ISL - Integer Set Library. Is that the difference ? UPDATE: Never mind the other package has also libisl as a dependency .

Sorry, a quick question, regarding C and C++ include files.

The Arch package riscv64-elf-gcc-12.2.0-2 has /usr/riscv64-elf/include as part of the package.

These do not appear to be bundled with this AUR build of riscv64-unknown-elf-gcc-13.2.0-2

Do you know of anyway to have these files included as part of the build?

Just for info, as needed riscv64-unknown-elf-gcc-14.1.0 for my FPGA project, changing the two lines...

pkgver=14.1.0

and

sha256sums=('e283c654987afe3de9d8080bc0bd79534b5ca0d681a73a11ff2b5d3767426840'

gives a working gcc-14.1.0 environment, generating code using the latest march flags for riscv64.

was fixed in https://github.com/cnlohr/ch32v003fun/commit/3c4fdca3a75d8c30b2c0aaf2607f7a78f9fb93cb

Hi, I'm trying to build https://github.com/cnlohr/ch32v003fun but when I install this and riscv64-unknown-elf-newlib, then try to "make" the "blink" example I get:

../../ch32v003fun/ch32v003fun.c: Assembler messages: ../../ch32v003fun/ch32v003fun.c:770: Error: unrecognized opcode csrw mstatus,a0', extensionzicsr' required ../../ch32v003fun/ch32v003fun.c:772: Error: unrecognized opcode csrw 0x804,a3', extensionzicsr' required ../../ch32v003fun/ch32v003fun.c:775: Error: unrecognized opcode csrw mtvec,a0', extensionzicsr' required ../../ch32v003fun/ch32v003fun.c:802: Error: unrecognized opcode csrw mepc,a5', extensionzicsr' required lto-wrapper: fatal error: riscv64-unknown-elf-gcc returned 1 exit status compilation terminated. /usr/lib/gcc/riscv64-unknown-elf/12.2.0/../../../../riscv64-unknown-elf/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status

can anyone help me here?

ch32v003fun recommends to install on ubuntu/debian, there the packages are libnewlib-dev and gcc-riscv64-unknown-elf. tested it in a VM, with them make works instantly.

Adopted the package and updated everything to the latest version. Some patches were required to get it to build again.

The current isl hosting platform seems to be sourceforge

https://libisl.sourceforge.io/

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.

esmil commented on 2018-03-01 09:32 (UTC)

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 https://github.com/esmil/pentagram

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