C++ Boost库初步使用 - 使用CFree

首先下载并安装 Boost；

在CFree中编写代码如下；

#include 
#include "resource.h"
#include 
//#include "C://local//boost_1_70_0//boost//regex.hpp"

using namespace std;
 
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);
 
HINSTANCE hInst;
TCHAR szClassName[] = TEXT("boostDemo");
boost::regex exampleregex( "boost::regex" );
boost::cmatch result;
 
int WINAPI
WinMain (HINSTANCE hThisInstance,
         HINSTANCE hPrevInstance,
         LPSTR lpszArgument,
         int nFunsterStil)
{
    HWND hwnd;
    MSG messages;
    WNDCLASSEX wincl;
 
	hInst = hThisInstance;
	
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;
    wincl.style = CS_DBLCLKS;
    wincl.cbSize = sizeof (WNDCLASSEX);
 
    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = MAKEINTRESOURCE (IDC_BOOSTDEMO);
    wincl.cbClsExtra = 0;
    wincl.cbWndExtra = 0;
    wincl.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
 
    if (!RegisterClassEx (&wincl))
        return 0;
 
    hwnd = CreateWindowEx (
           0,
           szClassName,
           TEXT("boostDemo"),
           WS_OVERLAPPEDWINDOW,
           CW_USEDEFAULT,
           CW_USEDEFAULT,
           500,
           200,
           HWND_DESKTOP,
           NULL,
           hThisInstance,
           NULL
           );
 
    ShowWindow (hwnd, nFunsterStil);
 
    while (GetMessage (&messages, NULL, 0, 0))
    {
        TranslateMessage(&messages);
        DispatchMessage(&messages);
    }
 
    return messages.wParam;
}
 
LRESULT CALLBACK
WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	PAINTSTRUCT ps;
	HDC hdc;
	RECT rt;	
	char szBuffer[100];	
	char *buf = "This is boost::regex example";
				
    switch (message)
    {
			case WM_COMMAND:
    		switch (LOWORD(wParam))
    		{
			case IDM_boost:		
				hdc=GetDC(hwnd);
				if( boost::regex_search( buf, result, exampleregex ) )
                {
                    //std::cout << result.str() << std::endl;
                    wsprintf(szBuffer, "%s",result.str());
					TextOut(hdc,20,20,szBuffer,lstrlen(szBuffer));
                }

				break;
		    case IDM_ABOUT:
				MessageBox (hwnd, TEXT ("boostDemo v1.0\nCopyright (C) 2020\n by bo"),
                        TEXT ("boostDemo"), MB_OK | MB_ICONINFORMATION);
				break;
			case IDM_EXIT:
				DestroyWindow(hwnd);
				break;
			default:
				return DefWindowProc(hwnd, message, wParam, lParam);	    		
		    }
    		break;
  		case WM_CREATE:
  			break;
    	case WM_PAINT:
			hdc = BeginPaint(hwnd, &ps);					
			GetClientRect(hwnd, &rt);				
			EndPaint(hwnd, &ps);
			break;
        case WM_DESTROY:
            PostQuitMessage (0);
            break;
        default:
            return DefWindowProc (hwnd, message, wParam, lParam);
    }
 
    return 0;
}

把boost目录拷贝到CFree的包含目录；

然后就能 #include ；<> 是表示系统路径；#include ""，这是自己的路径；

此示例调用Boost的正则库；还需要相关的lib和dll文件；

照此文操作；

    https://blog.csdn.net/bcbobo21cn/article/details/106147889

拷贝lib和dll到当前工程目录；

然后工程设置如下；

然后构建；出现错误；

    ld.exe: cannot find -lboost_regex-vc142-mt-x64-1_70

编译是没有问题；链接时候出错；

现在lib和dll有了；配置和 https://blog.csdn.net/bcbobo21cn/article/details/106147889 一样的；

为什么另一文会成功呢；看下CFree目录；当要使用自己的netapi32.lib和netapi32.dll时，CFree的库目录下有如下；

libnetapi32.a文件；目前要使用boost_regex-vc142-mt-x64-1_70.lib和dll；但是CFree的lib目录下没有 boost_regex-vc142-mt-x64-1_70.lib对应的.a文件；所以不能构建；

那么目前CFree 还不能支持Boost库；
