opencv anaconda error

when import cv2, there is an error

ImportError: /anaconda/bin/../lib/libm.so.6: version `GLIBC_2.15' not found (required by /usr/lib/x86_64-linux-gnu/libxvidcore.so.4)

just copy libm.so.6 from '/usr/lib/x86_64-linux-gnu' to '/home/username/anaconda/lib/'
then it can work

install rce in ubuntu14.04+ROS indigo with Anaconda python

~/rce$ sudo ./install.sh

會將rce相關套件裝到 /usr/local/lib/python2.7/dist-packages中

如要使用安裝在~/anaconda中的python會找不到rce相關套件

所以

~/rce$ ./setup/provision all

會import不到RCE套件

因此可以用以下兩種方式(擇一即可):

1. 將/usr/local/lib/python2.7/dist-packages中的相關套件與.pth檔複製到

    ~/anaconda/lib/python2.7/site-packages中

2.修改或新增.pth檔到~/anaconda/lib/python2.7/site-packages將相關的RCE egg指到

/usr/local/lib/python2.7/dist-packages

如:

/usr/local/lib/python2.7/dist-packages/rce_util-0.3-py2.7.egg

/usr/local/lib/python2.7/dist-packages/rce_comm-0.3-py2.7.egg

/usr/local/lib/python2.7/dist-packages/autobahn_rce-0.6.0.5-py2.7-linux-x86_64.egg

/usr/local/lib/python2.7/dist-packages/Twisted-14.0.2-py2.7-linux-x86_64.egg

/usr/local/lib/python2.7/dist-packages/rce_core-0.3-py2.7.egg

/usr/local/lib/python2.7/dist-packages/python_iptables-0.5.0-py2.7-linux-x86_64.egg

/usr/local/lib/python2.7/dist-packages/rce_client-0.3-py2.7.egg

/usr/local/lib/python2.7/dist-packages/rce_console-0.3-py2.7.egg

如有缺少zope.interface套件

可用 pip install zope.interface安裝

而RCE只支援到UBUNTU 13.04 + ROS hydro

如要使用UBUNTU 14.04 + ROS indigo需要修改provision檔

可將版本改掉

in my case: 

using 'tursty' to substitute 'Raring'

using 'indigo' to substitute 'hydro'

remove openvswitch-brcompat in _HOST_PKGS , becouse it cannot find it in ubuntu 14.04 and some one say ubuntu 14.04 for OVS don't need that.

compiling opencv with g++

There are two methods in compiling opencv with g++ without IDE

First is typing following command in command line directly

~$  g++ testcv.cpp -o testcv `pkg-config opencv --cflags --libs `

ps: ` place in the left of 1 on the keyboard, not ' in the left of Enter

 Second is to set a makefile as below:

testcv: testcv.cpp
g++  -o ${@} $<  `pkg-config opencv --cflags --libs `

and then type make in command line

~$ make

note:

keep the sequence of the command. put the `pkg-config opencv --cflags --libs ` after others.

If you make a command like

~$  g++  `pkg-config opencv --cflags --libs ` testcv.cpp -o testcv

there will be error

I don't know why...><

opencv on qt creater ubuntu

set .pro

INCLUDEPATH += /usr/local/include

LIBS += `pkg-config opencv --libs`

If an error occur like this

"Cannot connect creator comm socket /tmp/qt_temp.S27961/stub-socket: No such file or directory"

go to "Run Settings" and then cancel "Run in terminal"
