折腾一天的问题，SurfFeatureDetector type-specifier问题解决了。需要在cv.h中添加include nonfree/features2d.hpp。

from poster.encode import multipart_encode
ImportError: No module named poster.encode

sudo apt-get install python-poster

sudo apt-get install python-xmmsclient

sudo apt-get install python-pam python调用pam模块进行linux用户验证 http://blog.csdn.net/chenyulancn/article/details/8152931

sudo apt-get install xmms2 音乐播放器。没有的话，就报错。

File "/home/ppeix/tutorials/catkin_ws/src/qbo_webi/src/xmms2/xmms2.py", line 82, in __init__ subprocess.Popen(['/usr/bin/xmms2d'])

之后遇到这样的错误：

解决办法：直接安装qbo_questions。遇到依赖问题依次安装即可。

安装qbo_system_info

再安装abo_questions

然后再运行webi.launch

music_player 遇到getPath问题，添加roslib依赖库即可。

expression 遇到pymouth问题。删掉pymouth依赖库即可。

listen

camera

在工作主机上的/usr/share目录下找到了qbo-julius-model目录。文件夹是7.11日改写的。但现在已经不记得到底是如何安装上来的。
