Problem with Wwise SDK path when building an Android plugin

Question

I'm currently updating Wwise to 2019.2.1 and having difficulty rebuilding a plugin I wrote a couple of months ago. There are no changes to the plugin code which is thoroughly tested. It builds without any problems for Windows. I believe the Android build (using build tools) is failing due to the spaces in the Wwise SDK path.

When I run the build script I get the following output:

C:\Dev\Tools\HornetFilter>python "%WWISEROOT%/Scripts/Build/Plugins/wp.py" build Android -c debug
Building HornetFilter for Android in debug...
Building Android in debug using ndk-build. Build Command:

[armeabi-v7a] Install        : libHornetFilter.so => C:/Program/armeabi-v7a/libHornetFilter.so

The error "No rule to make target 'Files'" appears to be referring to part of "C:/Program Files (x86)/...." following the first space.

The final line shows the built lib being copied to "C:/Program/armeabi...." which also looks like a mangling of the Wwise path. The script has indeed created a folder C:\Program and copied files to it.

I have looked in the make files for a definition of the output paths but there isn't one so it must be defined somewhere in the scripts. How can I fix this?

Thanks

You are correct, the issue is related to the whitespaces being unescaped for make to process.

As a workaround, you can specify an installation of Wwise located in a path without spaces (e.g., you can copy the Wwise installation folder to your C:\ and build using this installation instead).
