LibHaru 库的问题

问题描述

我遇到链接错误的问题：

Error 112 error LNK2019: 未解析的外部符号函数中引用的 HPDF_Stream_WritetoStreamWithDeflate HPDF_Stream_WritetoStream C:\Users\tykab\OneDrive\Dokumenty\Visual Studio 2013\Projects\PDF2\PDF2\hpdf_streams.obj PDF2

我在这个项目中使用 Visual Studio 2013。源代码是用C语言编写的，我用的是C++ 与错误相关的 hpdf_stream.h 的头文件具有 extern "C" 标识符。我把这个标题的代码放在下面：

下面是导致链接错误的调用函数：

    void CPDF2View::OnInitialUpdate()
{
    CView::OnInitialUpdate();
    AfxGetMainWnd()->ActivatetopParent();

    HPDF_Doc pdf;
    pdf = HPDF_New(error_handler,NULL);
    HPDF_Page page_1;

    page_1 = HPDF_AddPage(pdf);
    HPDF_SavetoFile(pdf,"test.pdf");

    Invalidate(TRUE);
}

我使用 /VERBOSE 来诊断链接器输出，并且我得到 hpdflib.lib 未使用的信息。 sb 我能解释一下有什么问题吗？
