什么是你真正想要做设置参数？调试java可执行文件？或者调试Java程序（为什么存在更好的选择）？ – 2012-03-20 00:07:18
@DaveNewton：调试Java可执行文件以与其他Gdb和C调试团队共享，表示我的Java类由于那里的原因而断裂C包装有错误或者等等。 – YumYumYum 2012-03-20 00:27:20
您应该能够根据[this ]（http://publib.boulder.ibm.com/infocenter/realtime/v1r0/index.jsp?topic=/com.ibm.rt.doc.10/diag/problem_determination/linux_gdb.html）作为一个选项。 – 2012-03-20 00:44:39
