Buildfarm issues with shared libraries [closed]

Hi all,

I just decided to release for indigo a package that I had working for hydro and could not solve a problem with an external shared library. My package is avt_vimba_camera, a driver for Allied Vision Technologies cameras using ethernet (mainly). For that I need to use AVT SDK called VIMBA. In my package, I have VIMBA libraries and I "find_library" them from the CMakeLists.txt, who checks for the appropiate architecture (32 vs 64 bit).

The package itself compiles on my machine and on another machine with no issue at all, but on jenkins, the library cannot be found (example).

What is the difference on these builfarms that cause the library to be "NOTFOUND"?

Each job on the build farm starts with a "fresh" image which does not have any packages installed. Then it clones your repo and uses the information in the package.xml files to install declared dependencies.

I don't see any reference to the SDK in your package.xml ( https://github.com/srv/avt_vimba_came... ). That might be a reason why the build farm does not install it and therefore CMake can't find the library.

On your development machine you will have the SDK installed and therefore the library can be found.

It is in lib/{32,64}bit -> https://github.com/srv/avt_vimba_came...

This SDK has to be manually installed, that's why I unziped in lib/ and in include/ so that my executables can find it.

Nothing tries to search libraries in your sources lib folder for libraries. Also you don't install those libraries which means they would not even be part of the Debian package. May be on your development machine you have the libraries additionally in a different location?
