带Abbrevia GetIt包的ilink32链接器问题:ilink32错误未解决

Question

我试图在控制台应用程序中使用https://github.com/TurboPack/Abbrevia包和c++Builder。首先，我尝试手动安装软件包。但后来我在GetIt上找到了它。无论如何设置包，问题都将持续存在。我认为我手动进行的路径设置与包安装程序相同。对于Abdfbase::TAbDeflateHelper:：这是原始错误消息：

c:\pathtotheobjectfile\main.obj ilink32 Fehler错误: Nicht aufl sbares externes‘Abdfbase：：TAbDeflateHelper：：

仅仅设置路径和编译c++builder的项目(因此获取对象)就是所有的设置aks的目的。对于GetIt，我甚至不需要那么做。

这是我最简单的开始，我甚至连链接都没有。

#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。我遗漏了什么系统设置或特殊代码？

作为参考，导入的.hpp的开头显示了我试图实例化的类。

设置搜索路径不会告诉编译器/链接器您实际使用的是哪些特定库。您的项目没有链接到Abbrevia包库，因此出现了错误。

如果您创建了一个GUI应用程序，并在设计时将Abbrevia组件可视化地丢弃到TForm、TFrame或TDataModule上，那么就会为您添加必要的包库引用。

但是，在控制台应用程序中，如果没有至少一个TDataModule，则必须手动向项目添加对Abbrevia的.bpi包库的引用。
