Question regarding the quick start #337

Open huanpass opened 3 years ago

huanpass commented 3 years ago

Hi,

The quick start says export RISCV=/path/to/install/riscv/toolchain. I am a beginner to RISCV. Can i ask does the toolchain here means the riscv-gnu-toolchain namely the compiler? I wonder how i can set it up. It will be best if example provided.

Many thanks!

Yes, you need a riscv64-unknown-elf toolchain like riscv-gnu-toolchain, or an equivalent one. You can try building riscv-gnu-toolchain. Or you can try downloading one. There are some toolchain binaries on the SiFive web site on the software page. Debian has a toolchain that might work, but I think you would need a very recent version of debian to get access to it.

Hi Huanpass, You would have added PATH to riscv toolchain while installing riscv-toolcahin : https://github.com/riscv/riscv-gnu-toolchain You would have added this in your ./bashrc file. Ex : I had installed it in /opt/riscv/bin/ so my command would be: export RISCV=/opt/riscv/bin

Hope this helps.
