Hi!

I am using pyinstaller to generate a Windows .exe file out of my python project.  
When execuring the .exe file it complains about missing DSDL path (path goes to …/AppData/Local/Temp/… etc) when calling `load_dsdl()` from `uavcan/ __init__.py`

I can understand this. However, does anyone have an idea how to

1. include DSDL files into the pyinstaller generated package and make uavcan use them? Or
2. Specify relative paths in the python project so that stadnard DSDL files can be found at pre-defined location. The same for vendor\_specific\_types?

Or do I simply need to provide user input to both “dsdl\_files”- and “uavcan\_vendor\_specific\_types” paths and load them manually at startup?

Kinds Regards

This application might help you as an example, perhaps. It does not use DSDL, but it uses other resource files packaged tohether with the executables using PyInstaller:

Thanks! I have a look.

If I put my `own_namesace` folder with DSDL files in `$HOME/uavcan_vendor_specific_types`, and do not call load\_dsdl() from my own script, the parsed contents bewcomes present under `uavcan.thirdparty.own_namespace` as usual.

But if I call` load_dsdl([path])` with custom path to my namespace (have moved it from `$HOME/uavcan_vendor_specific_types` in to /tmp ) the `uavcan.thirdparty.own_namespace` is not present. Attached is a debug session screendump were `thirdparty` is missing `own_namespace`

Am I doing something wrong or does load\_dsdl() behave differently when parsing custom path compared to `~/uavcan_vendor_specific_types` ?

Sorry… My fault. I cannot import thirdparty before loading dsdl…
