[英]Help using PCRE in C++
this is my first time trying to build a C++ application, so I'm kind of lost. 这是我第一次尝试构建C ++应用程序,所以我有点迷失了。 I've looked at some examples but I still dont really know what's wrong.
我看了一些例子,但我仍然真的不知道出什么问题了。
#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;
}
When I try to compile, I get the following compiler errors 当我尝试编译时,出现以下编译器错误

_imp___ZN7pcrecpp2RE6no_argE
is a mangled name. _imp___ZN7pcrecpp2RE6no_argE
是错误的名称。 Since it contains the parts pcrecpp
and no_arg
, I suspect that the problem is that you fail to link against Pcrecpp. 由于它包含部件
pcrecpp
和no_arg
,我怀疑问题是您无法针对Pcrecpp进行链接。 Therefore, the no_arg
symbol is not defined. 因此,
no_arg
符号。
