c++ - 使用 CMake 和 MinGW 构建 PoDoFo 库

Question

我正在尝试在我的 Windows 平台上构建 PoDoFo 库(用作 API)。这是使用 CMake 完成的。 ReadMe 文件说明如下。不幸的是，我是 CMake 的新手，我无法从中了解很多。

Building PoDoFo on Windows

CMake 2.6.x is required for Windows. You can download it from cmake.org .

On Windows, PoDoFo may be built as either a shared or static library. Building both is not supported. By default only the shared library will be built. If you want a static library, just disable generation of the shared library with the extra argument to cmake:

    -DPODOFO_BUILD_SHARED=FALSE

Handling library naming on win32

Especially on Windows it is also common for custom built libraries to have different names to those you might download as pre-built copies. CMake won't be able to find them if they're called something else unless you tell it. Use these variables to tell CMake what names to look for a library under:

•FREETYPE_LIBRARY_NAMES_DEBUG, FREETYPE_LIBRARY_NAMES_RELEASE and FREETYPE_LIBRARY_NAMES
•TIFF_LIBRARY_NAMES_DEBUG, TIFF_LIBRARY_NAMES_RELEASE and TIFF_LIBRARY_NAMES 
•LIBJPEG_LIBRARY_NAMES_DEBUG, LIBJPEG_LIBRARY_NAMES_RELEASE and LIBJPEG_LIBRARY_NAMES
•ZLIB_LIBRARY_NAMES_DEBUG, ZLIB_LIBRARY_NAMES_RELEASE,ZLIB_LIBRARY_NAMES

CMake builds on Windows with MinGW

Once MinGW is set up, make sure that the MinGW "bin" directory is on your PATH, and be sure to set CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH such that CMake can find the headers and .lib files for the libraries PoDoFo requires. The GnuWin32 library packages from http://gnuwin32.sf.net/ are known to work with PoDoFo, so installing zlib, freetype, and libjpeg from there should do the trick.

To configure and build PoDoFo with a default GnuWin32 install and with MinGW already on your PATH:

md ..\podofo-debug 
cd ..\podofo-debug
cmake -G "MinGW Makefiles" ..\podofo-src -DCMAKE_INCLUDE_PATH=c:\progra~1\gnuwin32\include -DCMAKE_LIBRARY_PATH=c:\progra~1\gnuwin32\lib -DPODOFO_BUILD_SHARED:BOOL=FALSE mingw32-make

我已经安装了 CMake 并下载了提到的其他库，如 freetype、zlib、libjpeg。它们的头文件和二进制文件位于各自的文件夹中。

现在 DCMAKE_INCLUDE_PATH 和 DCMAKE_LIBRARY_PATH 应该是什么？还有什么是 "MinGW Makefiles"？我必须提供任何额外的参数吗？

如果有人能用简单的步骤解释我该怎么做，我将不胜感激。

编辑:执行 CMAKE 时出错:

-- Ensure you cppunit installed version is at least 1.12.0
Cppunit not found. No unit tests will be built.

Answer 1

要构建 PoDoFo，您需要安装 GnuWin32 , CMake, MinGW32 和 PoDoFo 来源

1. 下载GetGnuWin32
2. 安装到 c:\getgnuwin32
3. 打开cmd.exe
4. cd c:\getgnuwin32
5. download.bat
6. install.bat

然后按照@ibizaman 回答中的建议

cmake -G "MinGW Makefiles"  -DCMAKE_INCLUDE_PATH="C:\gnuwin32\include" -DCMAKE_LIBRARY_PATH="C:\gnuwin32\lib" -DPODOFO_BUILD_STATIC=TRUE ..

FreeType 应与 GnuWin32 软件包一起安装
