我正在尝试在控制台应用程序中将 abbrevia 包(https://github.com/TurboPack/Abbrevia)与 c++Builder 一起使用。首先,我尝试手动安装软件包。但后来我在 GetIt 上找到了它。无论如何设置软件包,问题仍然存在。我认为我手动进行的路径设置与软件包安装程序所做的相同。它总是导致 Abdfbase::TAbDeflateHelper:: 无法解析的外部这是原始错误消息:
[ilink32 Fehler] 错误:Nicht auflösbares externes 'Abdfbase::TAbDeflateHelper::'referenziert von c:\pathtotheobjectfile\main.obj
只需设置路径并为 c++builder 编译项目(因此获取对象)就是所有设置。有了 GetIt,我什至不必这样做。
这是我最简单的开始,我什至无法链接。
#pragma hdrstop
#pragma argsused
#ifdef _WIN32
#include <tchar.h>
#else
typedef char _TCHAR;
#define _tmain main
#endif
#include <stdio.h>
#include <AbDfBase.hpp>
using namespace Abdfbase;
int _tmain(int argc, _TCHAR* argv[])
{
TAbDeflateHelper* helper = new TAbDeflateHelper();
return 0;
}
这是我第一次尝试使用 c++builder。我缺少什么系统设置或特殊代码?
作为参考,导入的 .hpp 的开头显示了我尝试实例化的类。
