win10下CMAKE交叉編譯ARM-LINUX

WIN10下CMAKE交叉編譯ARM64-LINUX

平臺準備(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開發板
vscode編輯器

開始

首先設置好win10下make、cmake、arm-linux-gcc/g++等環境，在shell中查看

這樣環境編裝好了，接下來編寫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})

這裏編寫可以參考https://www.cnblogs.com/Trony/p/10952507.html
上面設置了交叉編譯器，環境、處理器平臺、輸出路徑等
然後便可以cmake了，這裏需要注意，在win10平臺下默認生成的是visual stduio2014的版本，需要指定生成標準unix makefile，這裏代碼如下：

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

然後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

最後得到hello_world執行代碼，這裏的hello_world代碼如下，打印環境變量

在開發板上掛載sd卡，並執行hello_world如下：

大功告成。
