Ubuntu
opencv package

opencv java

Asked by Michael Mehl

Hi all,

to use the package libopencv4.5-java additional steps are needed:

* "sudo apt install libopencv-dev" because "libopencv4.5d-jni" is not installed as dependency
* the library name has an additional "d" and to load the native library this has to be added: System.loadLibrary(Core.NATIVE_LIBRARY_NAME+"d");

Is it possible to update the package:
* include dependency (libopencv4.5-java -> libopencv4.5d-jni)
* adapt name of library-name

Kind regards
Michael

Which Ubuntu release and which version of the opencv package are you talking about?

According to https://launchpad.net/ubuntu/jammy/amd64/libopencv4.5-java/4.5.4+dfsg-9ubuntu4 the dependency of libopencv4.5-java on libopencv4.5d-jni (>= 4.5.4+dfsg-9ubuntu4) has been correctly set for the package in Ubuntu jammy.

For the naming "4.5d": This was defined by Debian and Ubuntu is just copying that into its own package.

My version is Ubuntu 22.04 LTS

Yes, you a right. The dependency is correct and works. I was confused when I tried to solve the "4.5d" problem.

About the "4.5d" issue I try to find the right place to ask the Debian community.

Can you help with this problem?
