Library (.so files) paths can be set with LD_LIBRARY_PATH. I forgot to mention that I had tried using LD_LIBRARY_PATH, but I didn't know about ADA_PROJECT_PATH or gnatls -v. I used gnatls -v on my local box: GNATLS 9.3.0 Copyright (C) 1997-2019, Free Software Foundation, Inc. Source Search Path: /usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/adainclude Object Search Path: /usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/adalib Project Search Path: /usr/x86_64-pc-linux-gnu/lib/gnat /usr/x86_64-pc-linux-gnu/share/gpr /usr/share/gpr /usr/lib/gnat Which lead to finding /usr/lib/gnat/gtkada.gpr Which showed me what files I had missed before and cleared up a lot of confusion about how to use some of the options in the gpr file. I added all the GtkAda files to my git repository so that the relative paths would match the gtkada.gpr file and added the ADA_PROJECT_PATH and LD_LIBRARY_PATH to the environment. *The build pipeline now see GtkAda.* Now I have to resolve a GNAT version discrepancy between the library and the pipeline. But for that one I know what to do... Thank you Onox for your guidance. You have save me a lot of time and pain.
