C++ compiler cannot create executables on Ubuntu

If you get the following error message when trying to compile some software application on Ubuntu (or Kubuntu or Xubuntu or similar) then you need to install the "build-essential" packages.

C++ compiler cannot create executables

This is simply a matter of opening up a command line prompt (but then
you were already there if you were trying to compile something) and
issue the following command: 
sudo apt-get install build-essential

You'll get some output like this, after which you should be able to continue trying to compile your software package

在论坛搜了很多，都说是编译环境没弄好，
sudo apt-get install build-essential
sudo apt-get install gcc
sudo apt-get install g++
都试过了，都说我是最新的版本，还是一样出错。
