Question

我在Linux上构建适用于Android的MuPDF时遇到了困难。我完全按照How to build MuPDF for Android

的指示进行了操作

运行命令'ant debug'时构建失败并出现以下错误 -

/home/georgew/AndroidSDK/android-sdk-linux/tools/ant/build.xml:653：执行此行时发生以下错误：

/home/georgew/AndroidSDK/android-sdk-linux/tools/ant/build.xml:698：null返回：132

我花了一天时间尝试Google可以找到的每个建议的解决方案。它们都会因此错误而失败，除了返回的null值可能会有所不同。

构建系统是运行Scientific Linux 6.3的Pentium4。 Ant是从源代码编译的，因为需要比SL6提供的更新的版本。

以下是运行'ant -d debug'

的最后一行输出

经过深入研究后，问题不在于建立MuPDF。问题是，较新版本的SDK中的aapt是使用SSE2支持编译的，并且在较旧的机器中被破坏。

可用的解决方案是在用于构建的机器上下载和编译SDK，安装SDK并在更现代的机器上构建项目，或者找到没有SSE2编译的最新版本的aapt的副本支持。

我搜索并找到了一个jar文件，apktool-2.0.jar，我从中提取了aapt并且构建成功完成。
