cross-compile in Ubuntu

unset LD_LIBRARY_PATH

after compile

set LD_LIBRARY_PATH

build riscv-gnu-toolchain

https://github.com/riscv-collab/riscv-gnu-toolchain

make linux:

./configure --prefix=/opt/riscv
make linux

make musl:

./configure --prefix=/opt/riscv
make musl

export PATH="$PATH:/opt/riscv/bin"

Upside not work for me,so I refer https://community.milkv.io/t/opencv-4-5-4/82

wget https://sophon-file.sophon.cn/sophon-prod-s3/drive/23/03/07/16/host-tools.tar.gz
tar xvf host-tools.tar.gz
cd host-tools 
touch riscv-crosstool-env-init 
nano riscv-crosstool-env-init 

content is:

HOST_TOOL_PATH=/xxx/xxx/xxx/host-tools

export PATH="$HOST_TOOL_PATH/gcc/riscv64-linux-x86_64/bin:$HOST_TOOL_PATH/gcc/riscv64-linux-musl-x86_64/bin:$HOST_TOOL_PATH/gcc/riscv64-elf-x86_64/bin:$PATH"

echo -e "\033[33;1mriscv交叉编译工具链环境配置完成！\033[0m"

in sdk root folder

source /xxx/xxx/xxx/host-tools/riscv-crosstool-env-init 

then you can compile the code
