[1.1.3] Ubuntu 18.04: only openCV 3.2 libs are available with aptget --- use SikuliX 1.1.4

Asked by RaiMan on 2018-06-11

but Ubuntu 18.04 only offers libopencv 3.2 which seems to not be recognized by Sikulix 1.1.2.

Error from log file:
ERROR: ...TEMP...: libopencv_core.so.2.4: cannot open shared object file: No such file or directory

You have to use 1.1.3 nightly with Java 10 - 1.1.2 doesn't work anyways.

--- opencv 2.4 (always needed with SikuliX 1.1.x)
You have to find a way to get this version running either from older/other repositories or by building it from sources yourself.

Another option is to try to rebuild the libVisionProxy against opencv 3:

... use the special setup with command line option buildv
... and modify the resulting build script accordingly

Thanks for the info.
Unfortunately, I would probably need a step by step procedure to do what you suggested.
So for now I'll run sikulix in a virtual Windows system, and hope sikulix 2 will work with the latest LTS Ubuntu when it comes out.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

I am running into this openCV issue on 18.04. So, just to confirm. Sikuli will not install and run on Ubuntu 18.04, correct?

SikuliX up to 1.1.3 need openCV 2.4. No way around.

SikuliX 1.1.4+ will always work with a recent OpenCV version (currently 3.2).
So you might try with 1.1.4. Should work with an installed OpenCV 3.2

Thanks @RaiMan. I ended up cloning one of my 16.04 VMs and used it instead of messing with 18.04.

good decision for the moment.

For 18.04 I am nearly ready with version 1.1.4:
- I have it working with OpenCV and Tesseract
- Tesseract is a challenge
- Open: I have to doc the steps to get there

should stay open
