1.下面是main.c文件代码：
#include <stdio.h>
int main(void)
{
printf("Hello World\n");
return 0;
}
2.下面是对应的CMakeLists.txt文件内容：
cmake_minimum_required (VERSION 2.8)
project (demo)
add_executable(main main.c)
3.编译时报错：

昨天尝试定位了一下，应该是交叉编译环境不支持32位编译导致的：set(CMAKE_C_COMPILER "${TOOLCHAIN_DIR}/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc")set(CMAKE_CXX_COMPILER "${TOOLCHAIN_DIR}/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-g++")
头文件搜索位置设置如下：
set(INCLUDE_PATH ${CMAKE_SYSROOT}/x86_64-arago-linux/usr/lib/aarch64-oe-linux/gcc/aarch64-oe-linux/11.4.0/include)
CMAKE_SYSROOT和TOOLCHAIN_DIR都是对应下面路径：
sdk安装目录\linux-devkit\sysroots
现在需要确认的应该集中在四个问题上：
1.SDK环境是否只支持编译64位的目标？
2.win10的ubuntu22.04虚拟机上交叉编译是使用x86_64-arago-linux下的编译工具吗？
3.gcc的头文件搜索位置设置是正确的吗？还需要确认g++的头文件搜索位置，否则不能编译cpp的文件；
4.为了编译64位目标时，CMAKE_C_FLAGS和CMAKE_CXX_FLAGS的编译选项怎么设置？

按照Andreas Dannenberg的建议，执行cmake出错：
[linux-devkit]:/home/qingfeng/workspace/ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07/hawk> cmake . -B build -DCMAKE_GENERATOR_PLATFORM=ARM64 -DCMAKE_TOOLCHAIN_FILE=./cmake/toolchains/aarch64_linux_buildroot.cmakeCMake Error at CMakeLists.txt:3 (PROJECT): Generator

qingfeng huang：
通过阅读下面链接：https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_DSP_CMAKE_GENERATOR_PLATFORM.html generators，例如Visual Studio Generators。
而我现在遇到的问题是基于sdk的linux-devkit搭建交叉编译环境，是两个方向。

请看下面e2e工程师的回复，他可以编译您的代码。
I tried building your CMake-based example in the context of the Linux devkit part of AM62A SDK v9.1 and had no issues. Please see log below. You can see how the aarch64 binary output file 'main' was generated successully.
