这是我第一次尝试构建C ++应用程序,所以我有点迷茫。我看了一些例子,但我还是不知道出了什么问题。
#include <iostream>
#include <stdio.h>
#include <windows.h>
#include <pcrecpp.h>
#include <string>
#include <cstring>
using namespace std;
int main()
{
char title[256];
char url[256];
string song, diff;
HWND hwnd = FindWindow("WindowsForms10.Window.8.app.0.33c0d9d", NULL);
GetWindowTextA(hwnd, title, 255);
pcrecpp::RE re("^osu! - (.*) \\[(.*)\\] \\[[|-]{21}\\]$");
re.FullMatch(title, &song, &diff);
sprintf(url, "xfire:game_stats?game=%s&%s=%s&%s=%s", "osu", "Playing", song.c_str(), "Difficulty", diff.c_str());
ShellExecute(NULL, NULL, url, NULL, NULL, SW_SHOWDEFAULT);
return 0;
}
当我尝试编译时,我得到以下编译器错误

答案 0 :(得分:5)
_imp___ZN7pcrecpp2RE6no_argE
是一个受损的名字。由于它包含部分pcrecpp
和no_arg
,我怀疑问题是您无法链接到Pcrecpp。因此,未定义no_arg
符号。
