Fix for pyqtdeploy-build bug on windows when folder and module have same name

My windows build was exiting silently with error code one. There was no error printed on this one either at the C++ level in pyqtdeploy_main or in pyqtdeploy.builder.builder so I ended up having to debug both layers for a while to figure it out. Eventually I figured out that pdytools_module.cpp:find_module couldn’t find my module “pkdiagram.debug”.

Turns out the module was never added to the project.

Turns out pyqtdpeloy.builder.builder silently ignores a python app module added to the pyqtdeploy project if a folder exists with the same filename. In my case I had a in my app module and also had a “debug” folder in the app module folder.

I added this poorly chosen exception to builder.builder to point it out. I do think it should fail if the file isn’t found since it was explicitly added in the project:

diff --git a/builder/ b/builder/

                 to_freeze.append((src_path, dst_name))
+            else:
+                raise RuntimeError("Skipping freezing module: %s, because file not found: %s" % (name, src_path))

         elif isinstance(part, PythonPackage):
             root = os.path.join(part_root_dir, src_name)

I imagine some error reporting could go a long way at both the C++ and python levels.
