请教性能调优工具systemtap安装时遇到的debuginfo内核安装问题
1.安装完systemtap后执行测试用例报错,网上查了下应该是debuginfo内核没安装
linux:/home/soft/SystemTap # /home/soft/SystemTap/bin/stap /home/soft/systemtap-1.1/testsuite/systemtap.examples/io/traceio.stp
semantic error: missing x86_64 kernel/module debuginfo under '/lib/modules/3.0.101-0.47.52-default/build' while resolving probe point kernel.function("vfs_read").return
semantic error: no match while resolving probe point vfs.read.return
semantic error: missing x86_64 kernel/module debuginfo under '/lib/modules/3.0.101-0.47.52-default/build' while resolving probe point kernel.function("vfs_write").return

Pass 2: analysis failed. Try again with another '--vp 01' option.
2.工作的linux服务器不能用网上的教程直接在线安装,想请教下如何离线安装?
3.问过其他同事,说可以自己用内核代码编译,请问如何入手?我需要看什么资料?
