在pdfium中创建一个dll

Question

我正在尝试为pdfium创建一个dll。我正在使用Visual Studio 2013（C++） 我试过了从https://github.com/pvginkel/PdfiumViewer以下的指令，但没有奏效（我想为一个不是PdfiumViewer的项目获得pdfium dll）。我收到以下错误：

2>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppBuild.targets(1193,5): warning MSB8012: TargetPath(\build\Debug\lib\pdfium.dll) does not match the Linker's OutputFile property value (C:\build\Debug\pdfium.dll). This may cause your project to build incorrectly. To correct this, please make sure that $(OutDir), $(TargetName) and $(TargetExt) property values match the value specified in %(Link.OutputFile).

有没有人有什么我应该做的想法？

Answer 1

我下载并构建了pdfium，如https://github.com/pvginkel/PdfiumViewer中所述。我的步骤：

1. 下载pdfium
2. 生成Visual Studio项目和解决方案
3. 开放的解决方案all.sln
4. 构建all.sln，错误LNK1112。我将项目pdfium的目标机器更改为/MACHINE:x86。现在一切正常，我得到的静态库
5. 我改变pdfium项目类型dll
6. 添加FPDFSDK_EXPORTS到预处理器定义
7. 添加依赖关系在https://github.com/pvginkel/PdfiumViewer
8. 描述更改的工具集来v120_xp
9. 编译器，连接器错误。我更改库列表（从$(OutDir)所有库）： kernel32.lib user32.lib advapi32.lib gdi32.lib winmm.lib $(OutDir)\lib\bigint.lib $(OutDir)\lib\fdrm.lib $(OutDir)\lib\formfiller.lib $(OutDir)\lib\fpdfapi.lib $(OutDir)\lib\fpdfdoc.lib $(OutDir)\lib\fpdftext.lib $(OutDir)\lib\freetype.lib $(OutDir)\lib\fx_lpng.lib $(OutDir)\lib\fxcodec.lib $(OutDir)\lib\fxcrt.lib $(OutDir)\lib\fxedit.lib $(OutDir)\lib\fxge.lib $(OutDir)\lib\gmock.lib $(OutDir)\lib\gtest.lib $(OutDir)\lib\gtest_main.lib $(OutDir)\lib\icui18n.lib $(OutDir)\lib\icuuc.lib $(OutDir)\lib\javascript.lib $(OutDir)\lib\jsapi.lib $(OutDir)\lib\pdfwindow.lib $(OutDir)\lib\v8_base_0.lib $(OutDir)\lib\v8_base_1.lib $(OutDir)\lib\v8_base_2.lib $(OutDir)\lib\v8_base_3.lib $(OutDir)\lib\v8_libbase.lib $(OutDir)\lib\v8_libplatform.lib $(OutDir)\lib\v8_nosnapshot.lib $(OutDir)\lib\v8_snapshot.lib
10. BUIL，现在一切正常，我得到动态LIB（DLL）
11. 我下载文件pdfiumviewer.cpp，并将其添加到项目
12. 编译，编译错误，找不到头文件
13. 将third_party\freetype\include;v8;v8\include;添加到包含的目录中
14. 生成，编译错误。
15. 在文件pdfiumviewer.cpp替换字符串#include "../../fpdfsdk/include/fpdfview.h"到#include "../../public/fpdfview.h"
16. 构建，现在一切正常，我得到动态LIB（DLL）

还有一件事，如果你想建立pdfium_test项目，你需要修复fpdfview.h文件：

#define DLLEXPORT __declspec(dllexport) 
#define STDCALL __stdcall 
#else 
#define DLLEXPORT 

#if !defined(_WIN64) 
// On Windows Win32 (not x64) requires __stdcall convention 
#define STDCALL __stdcall 
#else 
#define STDCALL 
#endif // !defined(_WIN64) 

#endif 

对于构建pdfium_embeddertests你可以关闭Treat warnings as errors的选择，但我不知道后果。
