Question: How to load library when dependencies are not in the LD_LIBRARY_PATH? #166

Closed Levi-Armstrong closed 4 years ago

I am currently releasing some visualization tools leveraging snap packages where they can be loaded dynamically using class_loader. In order for this to work correctly because the libraries dependencies are inside the snap packages folder and not in the LD_LIBRARY_PATH it fails to load. Now if I manually add the snap package path to the LD_LIBRARY_PATH it loads fine, but not a great solution because if globally added this could cause issues with other libraries using the snap packages resources. Does anyone have any ideas?

It looks like the best solution may be setting the RPATH of the plugin located in the snap package. I will test and report back.

Setting the RPATH solved the issue.
