Development Environment

环境变量 VISION_ROOT

安装CVL库后，会在环境变量中创建一个新的变量VISION_ROOT，该变量存储着CVL库的位置.

DLL路径

安装CVL库后，会在环境变量Path中添加CVL的dll路径：%VISION_ROOT%\bin\win64\cvl

CVL库头文件

Visual Studio C++ -> Properties -> C/C++ -> General -> Additional Include Directories -> $(VISION_ROOT)\defs

C++编译预处理宏 NOMINMAX

貌似这个可以不设置，Visual Studio C++ -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions -> NOMINMAX

CVL库lib文件

Visual Studio C++ -> Properties -> Linker -> General -> Additional Library Directories -> $(VISION_ROOT)\lib\win64\cvl

DLL

Visual Studio C++ -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions -> CVL7Library_EXPORTS, cmBuildingDLLs

stdafx.h

#ifdef CVL7Library_EXPORTS
#define DLLAPI __declspec(dllexport)
#else
#define DLLAPI __declspec(dllimport)
#endif

//下面这段代码，手册里的代码有错误，需要更正，其目的是使主程序导入静态库cogstds.lib，该静态库包含了CVL库必须的初始化和关闭程序，文件非常小，但是是必须的。
#ifndef cmBuildingDLLs
#pragma comment(linker, "/include:_cgLoadHardwareSupport")
#ifdef _DEBUG
#ifdef _UNICODE
#pragma comment(lib, "cogstds10_x64ud.lib")
#else
#pragma comment(lib, "cogstds10_x64d.lib")
#endif

#ifdef _UNICODE
#pragma comment(lib, "cogstds10_x64u.lib")
#else
#pragma comment(lib, "cogstds10_x64.lib")
#endif
#endif
#endif

主程序stdafx.h

#include "../CVL7Library/stdafx.h"

主程序需要初始化

//初始化CVL库
BOOL CWinApp::InitInstance()
{
    ...
	cfInitializeDisplayResources();
    ...
}

CVL9支持VS2022

需要修改CVL9的头文件, C:\Program Files\Cognex\CVL\defs\ch_cvl\defs.h
