Linux C++部分学习从一开始就不是很顺利，正如孙老师所言，学Linux会很辛苦，需要多下功夫。在Windows上安装虚拟机VMware并在虚拟机上安装Linux就费了很多时间，老师提供的VMware7.1.4装好后再安装老师提供的RedHat Linux Server 6.1-i386,结果不能正确安装code::blocks，因为Linux里没有安装gcc和g++。尝试了很长时间，在Software Centre里找不到distributes，利用sudo apt-get install 也不行。又尝试下载 tar ball，结果提示缺些库函数，下载了提示的库函数在./configure时又提示缺其他的库函数。最后下载的库函数源文件可以正确走过./configure，生成makefile，但 运行make 的时候又提示错误。

在网上下载了个VMware-9.0.1，安装了最新版的Ubuntu Linux 14.04后，结果很容易地通过Software Centre 找到gcc，g++，并安装好。后又顺利安装好了Code::Blocks。到此为止，好像用了一两个月，才算开始正式接触在Linux下编译C/C++程序。通过在Code::Blocks里编译运行老师教材里提供的练习程序，有了对在Code::Blocks 和 在Linux终端窗口编译C/C++程序的初步感觉。同时通过前面提到的长时间的安装，卸载Linux，各应用程序和库文件，对Linux的环境和在Linux环境下开发程序也有了初步的感觉。真的挺辛苦，不过回过头一看，感觉不像以前那样害怕Linux了。

培训教材的第三章我是结合我手头的一本《UNIX和Shell程序设计》中的部分章节一起学习的。从Bash（外壳）到Shell编程的一些知识点。到了3.7 Debugging一节，以前出现的问题又出现了。为了做练习题，需要安装memprof，结果Ubuntu Software Center中没有，用sudo apt-get install也不能安装。下载源文件自己./configure，提示没有gtk+-2.0和libglade-2.0，用sudo apt-get install gtk+-2.0可以正确安装gtk+库，但同样方法不适用于libglade-2.0。下载libglade-2.0源文件，./configure时提示确libxml，下载libxml源文件，运行./configure后能得到 “Done configuring”的成功提示，make 后 make install都很顺利，没有错误提示，我感觉应该是安装成功了。回头到libglade目录里 ./configure，这次能走通，但没有见到“Done configuring”的成功提示，只是在最后得到下面的结果，其中有几个no和一个false，都用红体字标识了：

If you want something that works with gtk+ 1.2, checkout the
libglade-1-0 branch with the following command
cvs update -r libglade-1-0 .
上面可疑的地方是这样一条警告：“./configure: line 10180: ./po/POTFILES.in: No such file or directory”。我查看了./po/目录，里面是空的，百度过，没有找到解决方案。Google到了一个回答，说可以忽略这个警告。不知该如何解决这个问题。

装不上memprof，百度到了个类似功能的替代品：valgrind，就是这个工具没有图形界面。

个人工作经验的理解：调试是找到程序问题和解决问题的“过程”，这句话太经典了，我在这章的学习过程中对此论述有了很深的理解。

我现在已经自学完3.11 Processes 进程。

请老师给发后面的视频。
