Answer 2

我碰到这个ISS我自己。简而言之，Ubuntu的systemtap软件包目前已经过期。

说明：前一段时间，内核更新了get_user_pages（）函数，这意味着任何使用前面函数原型的东西现在都无法编译。这也发生在VMWare的vmmon和vmnet模块上。运行stap时，它会生成一个使用get_user_pages（）的内核模块源文件，将其编译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。

目前没有解决方法：您可以从源代码编译的SystemTap（这是我做不到的事情，但我也没有很努力），或告诉Ubuntu的升级他们打破了SystemTap包 - 我提交了bug report，也许你可以确认它。

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

我有同样的问题，所以我最终从源代码构建systemtap。我在xenial上使用v3.1，到目前为止这么好。

## 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 ;
