i am beginner in ubuntu 12.04 and i dont know how command-line into it works?
i am trying to install open-cv 2.4.3 in it but i have some problems .
for example when i have tried to run this code :
sudo apt-get install libpnglite-dev libpngwriter0-dev libpngwriter0c2
i received this results :
what is the problem?
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libpngwriter0-dev
E: Unable to locate package libpngwriter0c2
i am doing it by following this instruction : opencv.willowgarage.com/wiki/InstallGuide %3A Debian
Generally i want to know how i can use the command-line?
how should i run this codes :
or i cant understand this instruction :
cd ~/<my_working _directory> git clone https://github.com/Itseez/opencv.git
- Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries.
- Enter the <cmake_binary_dir> and type
cmake [<some optional parameters>] <path to the OpenCV source directory>
cd ~/opencv mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
- Enter the created temporary directory (<cmake_binary_dir>) and proceed with:
make sudo make install
may anyone explain that how i should and what i should write in command line?
i am very grateful to him
