【问题描述】：

我尝试使用 CMake 为 aarch64 设备创建共享库（.so 文件），但是，cmake 编译了 x86-64 类型的脚本。我需要的是 ARM aarch64 格式。如果有人知道请帮帮我？

我的 cmake 文件：

PROJECT(deepsort)
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
cmake_policy(SET CMP0015 NEW)

AUX_SOURCE_DIRECTORY(./errmsg DIR_SRCS_errmsg)
AUX_SOURCE_DIRECTORY(./thirdPart DIR_SRCS_hungarianoper)
AUX_SOURCE_DIRECTORY(./thirdPart/munkres DIR_SRCS_munkres)
AUX_SOURCE_DIRECTORY(./thirdPart/munkres/adapters DIR_SRCS_munkres_adapters)
AUX_SOURCE_DIRECTORY(./matching DIR_SRCS_matching)
AUX_SOURCE_DIRECTORY(./feature DIR_SRCS_feature)
AUX_SOURCE_DIRECTORY(./common DIR_SRCS_common)
AUX_SOURCE_DIRECTORY(./api DIR_SRCS_api)

include_directories(
./errmsg
./thirdPart
./thirdPart/Eigen
./thirdPart/munkres
./thirdPart/munkres/adapters
./matching
./feature
./common
./api
)

add_library(deepsort SHARED 
$DIR_SRCS_errmsg 
$DIR_SRCS_hungarianoper 
$DIR_SRCS_munkres 
$DIR_SRCS_munkres_adapters 
$DIR_SRCS_feature 
$DIR_SRCS_matching 
$DIR_SRCS_api
)

include(CheckCXXCompilerFlag)  
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)  
CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)  
if(COMPILER_SUPPORTS_CXX11)  
        set(CMAKE_CXX_FLAGS "$CMAKE_CXX_FLAGS -std=c++11")  
elseif(COMPILER_SUPPORTS_CXX0X)  
        set(CMAKE_CXX_FLAGS "$CMAKE_CXX_FLAGS -std=c++0x")  
else()  
     message(STATUS "The compiler $CMAKE_CXX_COMPILER has no C++11 support. Please use a different C++ compiler.")  
endif()  

【参考方案1】：

我通过将 cxx 和 c 变量放在 Cmakelists.txt 文件中解决了这个问题：

set(tools /usr/bin)
set(CMAKE_C_COMPILER $tools/aarch64-linux-gnu-gcc)
set(CMAKE_CXX_COMPILER $tools/aarch64-linux-gnu-g++)

如果您想在不同的环境中编译，则必须下载链工具。
