How to cross compile to riscv64

[HoyiTT]

Hi Everyone. I want to build iwasm for riscv64 on x86_64 ubuntu(docker) But it doesn't works. I referred to the following link. https://github.com/bytecodealliance/wasm-micro-runtime/issues/1830

I installed RISC-V GNU Compiler Toolchain and export PATH=/opt/riscv/bin:$PATH, and then added lines to CMakeLists.txt

+SET(CMAKE_C_COMPILER riscv64-unknown-linux-gnu-gcc)
+SET(CMAKE_AR riscv64-unknown-linux-gnu-ar)
+SET(CMAKE_RANLIB riscv64-unknown-linux-gnu-ranlib)
+SET(WAMR_BUILD_TARGET "RISCV64")

and i tried

cmake ..
make

But it doesn't build..

Hello

If you applied the version, the path, and all that

Delete CmakeCache.txt in the cmake path and proceed with the cmake again

thank you

OMG

I installed riscv64-glibc-ubuntu-20.04-nightly-2022.12.17-nightly.tar.gz](https://github.com/riscv-collab/riscv-gnu-toolchain/releases/download/2022.12.17/riscv64-glibc-ubuntu-20.04-nightly-2022.12.17-nightly.tar.gz

and Delete CmakeCahec.tx and then

cmake ..
make

it work's!

Thank you!!!
