编译orb_slam3[windows]

作者：互联网

1 下载

git clone https://github.com/UZ-SLAMLab/ORB_SLAM3.git ORB_SLAM3

建议编译前，先看一下该项目上的一个pull request:(使用原来项目问题过多, 遇到的每一个问题在第4节都会详细描述，于是使用如下的一个PR)
https://github.com/UZ-SLAMLab/ORB_SLAM3/pull/53
推荐使用vs2015生成器;

2 编译

2.1 DBoW2 编译(如果使用pr，本步骤可以不看，2.3的orbslam3也对所有cmakelist.txt的修改做了说明)

主要是需要添加oepncv和boost的依赖

如果指定了vs2019，然后又用vs2015编译的库，就需要用如下的最后一个参数去掉boost的autolink;

mkdir build && cd build
cmake .. \
-G "Visual Studio 16" \
-DCMAKE_BUILDY_TYPE=Release \
-DOpenCV_DIR="F:/BASE_ENV/forOpenMVS/opencv/build" \

-DBOOST_ALL_NO_LIB=1 \     # 避免boost的autolink，autolink会要求vs版本和boost版本一致

2.2 g2o

项目->属性->c+±>预处器宏定义->添加： WINDOWS，否则会出现vasprintf找不到定义。

cd ../../g2o

echo "Configuring and building Thirdparty/g2o ..."

mkdir build
cd build
cmake .. \
-G "Visual Studio 14" \
-DCMAKE_BUILDY_TYPE=Release \
-DEIGEN3_INCLUDE_DIR="F:\BASE_ENV\forOpenMVS\eigen" \
-DBOOST_ALL_NO_LIB=1 \

2.3 orbslam3

2.3.0 首先按照下面的diff修改所有的internal::axpy和internal::atxpy

如果你是自己在orbslam3直接编译的话，请参考: https://github.com/RainerKuemmerle/g2o/issues/91

2.3.1 找不到unistd.h

首先：unistd.h需要修改调，主要是为了使用usleep，该函数使用如下代码替换：

```cpp
#include <windows.h>

void usleep(__int64 usec) 
{ 
    HANDLE timer; 
    LARGE_INTEGER ft; 

    ft.QuadPart = -(10*usec); // Convert to 100 nanosecond interval, negative value indicates relative time

    timer = CreateWaitableTimer(NULL, TRUE, NULL); 
    SetWaitableTimer(timer, &ft, 0, NULL, NULL, 0); 
    WaitForSingleObject(timer, INFINITE); 
    CloseHandle(timer); 
}

或者如下一行能搞定：推荐这个方法

            if (ttrack < T) {
                long usec = static_cast<long>((T - ttrack) * 1e6);
                std::this_thread::sleep_for(std::chrono::microseconds(usec));
            }

2.3.2 使用cmake-gui开始编译

cmake-gui配置：
opencv，boost，需要修改cmakelist.txt:
添加如下定义：

-DBOOST_ALL_NO_LIB=1

如下是我对cmakeList.txt做出的修改。

4 可能遇到的问题

4.1 g2o -> vasprint 找不到标识符

到它的声明处，就会发现，它的声明和定义均位于非活动预处理器块中，被宏定义WINDOWS关闭了。所以添加对应的宏定义即可：右键项目->属性->C+±>预处理器->预处理器定义，为其添加一个变量，WINDOWS，保存设定之后，这个错误也就消失了。
以上过程也可以在cmakelist.txt中添加： ADD_DEFINITIONS(-DWINDOWS)

4.2 orb-slam3 -> cl.exe has no C++11 support. Please use a different C++ compiler.

因为cmakelist对于cl的c++11的支持方式需要如下编写：

4.3 stdio-gcc.h找不到

将其改为stdio.h即可

4.4 Failed to run MSBuild command: C:/Program Files (x86)/MSBuild/14.0/bin/MSBuild.exe

将上述的MSBuild.exe添加到里面，然后https://developer.microsoft.com/zh-cn/windows/downloads/sdk-archive/
里面找到win8.1的sdk，安装即可。

4.5 fata_error: compiler internal error on msc1.cpp:1xxx编译器内部错误

和g2o/core/matrix_operation.h的代码有关系，参考如下修改：
https://github.com/RainerKuemmerle/g2o/issues/91
https://github.com/UZ-SLAMLab/ORB_SLAM3/pull/53

4.6 std::max找不到定义

添加：

#include <algorithm>

4.7 找不到openssl/md5.h

可以尝试安装strawberry-perl，里面有oepnssl的库，然后下载openssl的源码获得其include。
这里也有openssl编译好的链接库： https://indy.fulgan.com/SSL/LinkLibs/
我的下载地址为：https://indy.fulgan.com/SSL/LinkLibs/openssl-1.0.2g-x64_86-win64_LinkLibs.zip

配置完成后比如一些openssl的依赖就需要手动添加了：
