Building tools from manage.py failing on OSX

[Patrick Boelens (bluetomato)]

Hey there!

I figured I'd give your engine a try (it looks great!), but got stuck at building the tools nescesary for the first 3D example. From the turbulenz_engine root and in my env I run "$ python2.7 manage.py tools" and get the following output:

Creating: /Applications/XAMPP/xamppfiles/htdocs/SpaceVoxels/turbulenz_engine/tools/bin/macosx
Executing: make

[ERROR] - Command 'make' returned non-zero exit status 2

Any help would be much appreciated!

Cheers,

Just quickly check two common errors:

1. Have you activated the environment using 'source env\bin\activate' (You should see an '(env)' at the start of your prompt)?

2. Have you installed the Cg toolkit as part of the prerequisites? https://github.com/turbulenz/turbulenz_engine#pre-requisites

Note: once you have the env activated you should be able to call 'python' instead of 'python27' and it should use the one you setup with the environment. To check your env has the correct python you should run 'python' and type:

import sys
sys.executable

This should be something like: /Applications/XAMPP/xamppfiles/htdocs/SpaceVoxels/turbulenz_engine/env/bin/python

D'ow, now I feel stupid, I had missed the CgToolkit prerequisite. In my defense though, the wording seems to imply it's included with the download: "NVIDIA CgToolkit version 3.1 or higher. This is included in the repository for Windows, for Mac OSX and Linux please download and install it."

Anyway, thanks for your help!

We've updated the docs to try and be a bit clearer that linux and osx require the download so I'll close this issue.
