win10下CMAKE交叉编译ARM-LINUX

WIN10下CMAKE交叉编译ARM64-LINUX

平台准备(接上一篇文章)

win10
cmake
arm-linux-gcc（aarch64-linux-gnu-gcc-7.3.1.exe）
arm-linux-g++（aarch64-linux-gnu-g++.exe）
make
zcu106开发板
vscode编辑器

开始

首先设置好win10下make、cmake、arm-linux-gcc/g++等环境，在shell中查看

这样环境编装好了，接下来编写CMakeLists.txt
如下：

cmake_minimum_required(VERSION 2.8)

#set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_C_COMPILER "aarch64-linux-gnu-gcc-7.3.1.exe")
set(CMAKE_CXX_COMPILER "aarch64-linux-gnu-g++.exe")

project(hello_world)

include_directories(inc INC_LIST)

aux_source_directory(src SRC_LIST)

add_executable(hello_world main.c ${SRC_LIST})

这里编写可以参考https://www.cnblogs.com/Trony/p/10952507.html
上面设置了交叉编译器，环境、处理器平台、输出路径等
然后便可以cmake了，这里需要注意，在win10平台下默认生成的是visual stduio2014的版本，需要指定生成标准unix makefile，这里代码如下：

PS C:\Users\Donce Jiang\Desktop\graduate\code\pro> cmake -G "Unix Makefiles" .

然后make

PS C:\Users\Donce Jiang\Desktop\graduate\code\pro> make
Scanning dependencies of target hello_world
[ 33%] Building C object CMakeFiles/hello_world.dir/main.c.o
[ 66%] Linking C executable /bin/hello_world
[100%] Built target hello_world

最后得到hello_world执行代码，这里的hello_world代码如下，打印环境变量

在开发板上挂载sd卡，并执行hello_world如下：

大功告成。
