No Linux/Ubuntu riscv-none-embed-gcc compiler available

[lbattraw]

I tried adding this core to my v1.8.19 Arduino IDE board manager on my Ubuntu 22.04/"Jammy Jellyfish" x86 Linux and got the error: Tool riscv-none-embed-gcc is not available for your operating system.

I also tried v2.2.1 of the Arduino IDE and got a similar error: Downloading packages Failed to install platform: WCH:ch32v. Error: 13 INTERNAL: Error downloading tool WCH:riscv-none-embed-gcc@8.2.0: no versions available for the current OS, try contacting tech@wch.cn

Is this core only available for Windows? Also is there anything I can do to help get this OS supported for arduino_core_ch32?

I have the same problem :(

The compiler for Linux and Mac is available, it's just not listed in the package index.

The raw toolchains can be gotten from http://www.mounriver.com/download or my mirrors

• https://github.com/Community-PIO-CH32V/toolchain-riscv-mac
• https://github.com/Community-PIO-CH32V/toolchain-riscv-linux/

Still, the people in this repo need to fix it.

I'm integrating this core into PlatformIO, where a CH32V003 example compiles fine on Windows, Linux and Mac. Currently work in progress.

Same behaviour on Arduino IDE 2.2.1 Failed to install platform: 'WCH:ch32v:1.0.3'. Error: 13 INTERNAL: Error downloading tool WCH:riscv-none-embed-gcc@8.2.0: no versions available for the current OS, try contacting tech@wch.cn

You know what, let me just whip up an expanded package_ch32v_index.json version that just has links to my repos for the missing toolchains. That should actually make it go through.

Edit: Let's see how https://gist.githubusercontent.com/maxgerhardt/e270b2c3294a5f7a6cfd9e2d0d16382e/raw/7fdea01979081749fac9c1e092147ea93fd8a951/arduinowch_package_index.json goes...

works for me with Linux.

Don't have time to repackage OpenOCD for Mac (and besides the Linux hoster at catbox is just temporary), but it does prove the concept..

Confirmed working onArduino IDE 2.2.1,& Arduino IDE 1.8.19 does install and compiles minimal example.

Thank you very much for your contributions!

I hope WCH merges these changes upstream quickly.

I'm sorry for waiting until now to address these issues. Both Linux and MAC environments are available now.

[maxgerhardt]

Looks good in regards to toolchain and OpenOCD now, but is it right that all Linux, Windows and MacOS systems reference the before_install package with wch_beforeinstall_linux-1.0.0.tar.gz which has Linux .so library files?

[TianpeiLee]

I noticed this issue. Other environments try not to include it, but when other environments' IDEs download the installation package based on the same "toolsDependencies", they will report an error. For the sake of simplicity, I have added all of this package.
