标题: rga代码cmake出问题 [打印本页] 作者: hanhaowen 时间: 2021-6-23 11:14 标题: rga代码cmake出问题 GitHub - rockchip-linux/linux-rga的代码，修改了buildroot.cmake后，在build文件夹下执行cmake-linux.sh，出现如下问题：
Generated version.h
set buildroot toolchain
-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= /home/forlinx/OK3399/OK3399-desktop-release/prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc
default to Release build for GCC builds
RGA is compiling with cmake

请问该怎么做？
build文件夹下的cmake-linux.sh文件的内容如下：
