为Android构建MUPDF

Question

我是使用NDK的新手，我想为我的PDF Viewer项目构建MUPDF库，我在应用程序中跟随了Integrate MuPDF Reader，并且此ReadMe.txt也出现了以下错误：。

希望有人可以在这里帮助我。

Answer 1

在mupdf-0.9文件夹中，在android文件夹中运行ndk-build之前，运行命令make 。

Answer 2

看这里

• 首先，在电脑上安装android NDK
• 然后下载mupdf 0.8.15源代码（不要下载1.0版本，在1.0.0中没有mupdf源代码）
• 下载第三方zip软件包（mupdf-thirdparty-2011-02-24.zip），网址：mupdf.com//download/archive，

您将成功编译。
