Here we place all of the concerns when migrating to a newer version of opencv or the repercussions of not upgrading.

+
−
=== Migration to Python 3 ===
+
−
* Opencv 2.4.3 does not support Python 3
+
−
 
+
−
=== Camera drivers ===
+
−
* Currently, only some camera drivers are supported with the new version of opencv, leading to problems regarding capture. One issue is the inability to cancel the program webcam capture.
+
−
 
+
−
=== Yum repo ===
+
−
* Right now, only the 2.3.1 version of opencv is available in the yum repository

Standard Dev Environment

  • Fedora 18
  • OpenCV 2.4.X - whatever recent version is supported
  • Python 2.X/Python 3.X

Complete Git and Mousetrap Install

Install git and Clone MouseTrap 

 Open a terminal and
 Run Commands:
 -> sudo yum install git-core                           # Install git 
 -> sudo yum -y update gnome-common glib2-devel\
    intltool python-devel opencv-python python-xlib     # Update all dependencies, MUST be done before install
 -> sudo yum -y install gnome-common glib2-devel\
    intltool python-devel opencv-python python-xlib     # Install latest versions of dependencies
 -> git clone git://git.gnome.org/mousetrap -b gnome3-wip # Clone the git repo to your computer

Install MouseTrap 

 Run Commands:
 -> cd mousetrap
 -> ./autogen.sh                       # Set up MouseTrap
 -> make                               # Compile MouseTrap
 -> make install                       # Install Mousetrap executable in appropriate directory
 -> mousetrap                          # Execute MouseTrap. You may see warnings on your console

Commit Changes - Deprecated 

 -> git status                         * Shows all of the modified files
 -> git add *                          * This is to add ALL files to commit list (MAKE SURE YOU WANT THEM ALL FIRST!)
 -> git commit                         * Add a useful title to first line of your commit.
                                         This is in vim so 'i' to insert ':x' to save and quit.
 -> git push origin INSERT_BRANCH_NAME * This must be the branch you created in the git install.
                                         This will ask for your git credentials, so have them ready.
