具体错误：
gluegen.build.javase: generate.java: BUILD FAILED /home/tsit/jogamp232-loongarch64/gluegen/make/build.xml:957: The following error occurred while executing this line: /home/tsit/jogamp232-loongarch64/gluegen/make/build.xml:694: The following error occurred while executing this line: /home/tsit/jogamp232-loongarch64/gluegen/make/build.xml:653: Problem: failed to create task or type antlr Cause: the class org.apache.tools.ant.taskdefs.optional.ANTLR was not found. This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in -/home/tsit/apache-ant-1.10.11/dist/lib -/home/tsit/.ant/lib -a directory added on the command line with the -lib argument Do not panic, this is a common problem. The commonest cause is a missing JAR. This is not a bug; it is a configuration problem
什么意思？就是ant缺少东西。原因是吾自己下载编译了ant（因为到目前为止，loongarch64平台没有ant可更新安装），实际上lib的内容不对。解决办法：
检查版本
Apache Ant(TM) version 1.10.5 compiled on August 27 2018
下载ant
Index of /ant/binaries
Apache Ant - Binary Distributions
Index of /dist/ant/binaries
这个链接可以下载各种老版本。
复制缺少的jar
我们只复制需要的jar，如ant-antlr.jar。目录应该是/usr/share/ant/lib
