在ubuntu上安装systemtap之后，测试示例hello-stap.stp.but但是有一些错误。

我该如何解决这个问题？

感谢

您好-stap.stp

probe begin
{
    print("hello world\n")
    exit()
}

这是错误信息。

Answer 1

我自己遇到了这个问题。简而言之，Ubuntu的systemtap软件包目前已经过时了。

解释：前一段时间，内核更新了get_user_pages（）函数，这意味着使用上一个函数原型的任何东西现在都无法编译。这也发生在VMWare的vmmon和vmnet模块上。当您运行stap时，它会生成一个内核模块源文件，该文件使用get_user_pages（），编译它并将其加载到内核中。但它生成的C代码使用旧的函数定义，因此无法构建。

目前没有解决方案：您可以从源代码构建SystemTap（我没有做到，但我也没有非常努力）或告诉Ubuntu升级他们破损的systemtap软件包 - 我提交了一个bug report，也许你可以确认一下。

我的解决方案是切换到Fedora 26并运行/ usr / bin / stap-prep来安装先决条件。工作没有任何打嗝！

Answer 2

我遇到了同样的问题，所以我最终从源代码构建了systemtap。我在xenial上使用v3.1，到目前为止一直很好。

## Install build-required packages
apt-get update && \
        apt-get install -y build-essential gettext elfutils libdw-dev python wget tar && \
        apt-get clean;

## Build from source
wget https://sourceware.org/systemtap/ftp/releases/systemtap-3.1.tar.gz
tar xzvf systemtap-3.1.tar.gz

## Instruction: https://sourceware.org/git/?p=systemtap.git;a=blob_plain;f=README;hb=HEAD
cd systemtap-3.1/ && \
         ./configure && \
         make all && \
         make install ;
