我想使用OCaml分析OCaml文件(.ml).我想将文件分解为抽象语法树进行分析.我试图使用camlp4,但没有运气.有没有其他人成功地做过这件事？这是解析OCaml文件的最佳方法吗？
我正在尝试从Wallet.java生成CAP文件和导出文件,该文件是samples目录下的Java Card SDK中的标准.我编译类,使用转换器并遇到以下问题:
$ javac -g -d classes/ src/com/sun/javacard/samples/wallet/Wallet.java
$ converter -debug -verbose -classdir "$JC_HOME/samples/src" com.sun.javacard.samples.wallet 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x6:0x1 1.0

error: com.sun.javacard.samples.wallet.Wallet: unsupported class file format of version 50.0.
conversion completed with 1 errors and 0 warnings.
我的Java版本和javac版本是相同的,Java 1.6:
$ java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, …在我的Docker容器构建过程中,我尝试使用apt-get install安装一些软件包.但是,该过程未能完成,因为无法找到4个包中的3个.
