Example does not run

[alexbirkett]

I can't run the example on macOS Mojave Version 10.14.5:

Alexs-MacBook-Pro-2124:keygen alex$ bin/keygen.py scad/kwikset.scad --bitting 25536 -o housekey.stl

Running export SCAD=/Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD prior to bin/keygen.py scad/kwikset.scad --bitting 25536 -o housekey.stl fixes the error above but then I get

It looks like your OpenSCAD isn't finding the included file kwikset.gen.scad.

According to this page on OpenSCAD's wiki,

Library files are searched for in the same folder as the design was open from

but your OpenSCAD doesn't seem to be searching there.

It might be searching the current working directory. Try this:

cd scad
../bin/keygen.py kwikset.scad --bitting 25536 -o housekey.stl

What version of OpenSCAD do you have?

[ervanalb]

Did you get this running? I would like to close this issue.

I am having the same issue on Mac. I was getting the same error above of:

Traceback (most recent call last):
  File "bin/keygen.py", line 36, in <module>
    r = subprocess.call([scad, args.filename, "-o", args.output] + opts + remaining)

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'openscad': 'openscad'

I then tried export SCAD=/Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD as @alexbirkett suggested and got the same type of errors:

WARNING: Can't open include file 'kwikset.gen.scad'.

I also tried starting in the scad directory as you suggested but the same errors above persisted.

for me, there is no kwikset.gen.scad file - I'm getting the same errors as above on Mac with OpenSCAD 2019.05.

FYI, I got this working by checking out a really old release. The kwikset.gen.scad was in the repo.

[ervanalb-vs]

I have added the .gen.scad files to the repo. They can be re-generated by running make, but this requires Inkscape to be installed.

Thanks @ervanalb-vs
