在执行3.2.1.3.1中的步骤时、SDK_INSTALL_DIR 的定义/位置似乎缺失/未定义。

快速操作
Grep -Rnw ' '-e 'SDK_INSTALL_DIR'
会产生3个命中点、其中一个是定义
/home/james/ti-processor-sdk-linux-am64xx-evm-10.00.07.04/linux-devkit/sysroots/x86_64-arago-linux/usr/share/cmake/SDKToolchainConfig.cmake.template:1:set(SDK_INSTALL_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../../..") /home/james/ti-processor-sdk-linux-am64xx-evm-10.00.07.04/linux-devkit/sysroots/x86_64-arago-linux/usr/share/cmake/SDKToolchainConfig.cmake.template:2:set(HOST_SYSROOT "${SDK_INSTALL_DIR}/sysroots/@OECORE_SDK_SYS") /home/james/ti-processor-sdk-linux-am64xx-evm-10.00.07.04/linux-devkit/sysroots/x86_64-arago-linux/usr/share/cmake/SDKToolchainConfig.cmake.template:3:set(TARGET_SYSROOT "${SDK_INSTALL_DIR}/sysroots/@OECORE_TARGET_SYS")
对 SDK_INSTALL_DIR 进行导出、然后重新执行初始导出即可解决这个问题
添加了示例
export SDK_INSTALL_DIR="/home/james/ti-processor-sdk-linux-am64xx-evm-10.00.07.04" export CROSS_COMPILE_64="${SDK_INSTALL_DIR}/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-" export SYSROOT_64="${SDK_INSTALL_DIR}/linux-devkit/sysroots/aarch64-oe-linux" export CC_64="${CROSS_COMPILE_64}gcc --sysroot=${SYSROOT_64}" export CROSS_COMPILE_32="${SDK_INSTALL_DIR}/k3r5-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-eabi/arm-oe-eabi-"
我想、SDK_INSTALL_DIR 是可能是通过运行我以某种方式遗漏的另一个脚本或二进制来设置的。
