I removed the previous 2019.05 version, reloaded version 2019.05 and placed the .scad files in the libraries/BOSL2 folder. I still have the old version of OpenSCAD 2015.03-2 loaded on the computer. Still getting the errors. Here is the complete error message: Loaded design 'C:/Users/Graphics/Documents/OpenSCAD/libraries/BOSL2/bosl2.scad Parsing design (AST generation)...

As I said, I don't think the OpenSCAD versions have anything to do with the problem. Your BOSL2 directory contains at least one wrong file, namely a file that should be in BOSL2/test. If one file is wrong, probably many other things are wrong too. Messing with OpenSCAD won't fix this. You need to wipe out all your BOSL2 files, and unzip BOSL2 again and make sure it creates the full directory structure and that you have exactly the files I listed above (no other ones) in your BOSL2 directory. Note that you don't want all the .scad files from BOSL2 in the BOSL2 folder. The tests need to stay in the tests folder. (Or you actually don't need them at all.) The output below shows that the correct hull.scad in BOSL2 has been overwritten by tests/hull.scad. cbernhardt wrote > I removed the previous 2019.05 version, reloaded version 2019.05 and > placed > the .scad files in the libraries/BOSL2 folder.

I downloaded the BOSL files here: https://github.com/revarbat/BOSL2/archive/master.zip There is no directory structure in the ZIP file. Where should I get the proper file? -- Sent from: http://forum.openscad.org/

I unzipped the file without the directory structure. Unzipping with the "Use folder names" checked solved the problem. Thanks all. Charles -- Sent from: http://forum.openscad.org/

I think you were confounded by this bug https://github.com/openscad/openscad/issues/3531 The warning can report the wrong file. When I downloaded BOSL2, unzipped it into directory 'BOSL2', it had an extra directory 'BOSL2-master/', so the includes wouldn't work, I just had to move everything up one level, ie copy contents of 'BOSL2-master/' up, then delete the empty 'BOSL2-master/'. ----- OpenSCAD Admin - email* me if you need anything, or if I've done something stupid... * on the Forum, click on my MichaelAtOz label, there is a link to email me.
