Ok. So I only have an old Veriton M460 with Intel Pentium that however seems to work fine.
Since the site "http://docs.opencv.org/ref/master/d7/..." declared that
"These steps have been tested for Ubuntu 10.04 but should work with other distros as well."
I downloaded Ubuntu 10.04 LTS, certain of a positive result!
Unfortunately I did not go far...
on the second comand to retrieve the required packages (sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev) I received a smarty remark stating that:
the package is not available (missing, obsoleted or only available from other source)
E: Package git has no installation candidate
:-/
Well I did not loose my will: I downloaded Ubuntu 12.04 LTS and tried again...
I managed to complete the 3 required package downloads (hiphip hurra!) and set off to follow the other instructions.
On point 2 (configuring) I wrote the magic sentence "cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .."
But I received a non encouraging "The source directory "/home/... does not appear to contain CMakeLists.txt"
So I went with what seemed could solve the issue, the comand line: sudo apt-get install cmake-qt-gui :-))
I thought it had worked :-)... But checkmate however came immediately after: with a "make: invalid option -- 'D' "
My hopes colapsed: could not find a way to go any further...
So I am back to Ubuntu 14.04 and no OpenCv.
Can anyone suggest step by step instructions (a book, youtube, tutorial etc) that a willing yet desperate novice can follow?
Hope I don't have to go back to Windows... :-(
... and thanks for reading, at least I feel better now... :-)
