I’m trying to build the engine on windows 10. Using mingw32 shell I get this message: Waf: The wscript in ‘e:\DefoldSource\defold\engine\dlib’ is unreadable Traceback (most recent call last): File “e:\DefoldSource\defold\tmp\dynamo\_home\ext\bin\waf-2.0.20-36f5354d605298f6a89c09e0c7ef6c1d\waflib\Scripting.py”, line 102, in waf\_entry\_point set\_main\_module(wscript) File “e:\DefoldSource\defold\tmp\dynamo\_home\ext\bin\waf-2.0.20-36f5354d605298f6a89c09e0c7ef6c1d\waflib\Scripting.py”, line 142, in set\_main\_module Context.g\_module=Context.load\_module(file\_path) File “e:\DefoldSource\defold\tmp\dynamo\_home\ext\bin\waf-2.0.20-36f5354d605298f6a89c09e0c7ef6c1d\waflib\Context.py”, line 362, in load\_module exec(compile(code,path,‘exec’),module. **dict** ) File “e:\DefoldSource\defold\engine\dlib\wscript”, line 9, in import Options ImportError: No module named Options None Traceback (most recent call last): File “scripts/build.py”, line 1919, in f() File “scripts/build.py”, line 891, in build\_engine self.\_build\_engine\_lib(args, lib, host, skip\_tests = skip\_tests) File “scripts/build.py”, line 861, in \_build\_engine\_lib run.env\_command(self.\_form\_env(), args + plf\_args + self.waf\_options + skip\_build\_tests, cwd = cwd) File “e:\DefoldSource\defold\build\_tools\run.py”, line 63, in env\_command return \_exec\_command(args, shell = False, stdout = None, env = env, \*\*kwargs) File “e:\DefoldSource\defold\build\_tools\run.py”, line 41, in \_exec\_command raise ExecException(process.returncode, output) run.ExecException Thanks ---

Did you install waf manually? Looks like you’re on a different version than the one installed using install\_ext. ---

I’m not on windows so can’t check, but in general I think you should first run the package script **package\_win32\_sdk.sh** under script/package. That should create a WindowsKits_something_ in a **packages** folder. When running **build.py install\_ext …** , it expects to download packages from the path pointed to by the **–package-path** argument. That argument probably should accept local file paths, but I think for now it actually needs to be a url. I usually start a simple web server in my **packages** folder, using python: **python -m SimpleHTTPServer** (if using python 2.7, as you should when building defold). Then the install\_ext command line should be something like **./scripts/build.py install\_ext --platform=x86\_64-win32 --package-path=[http://0.0.0.0:8000](http://0.0.0.0:8000)** It looks like the WindowsKit version is slightly off right now, so you’ll probably need to tweak the numbers used in the scripts. ---

Just confirming that you need to run a HTTP file server for the packages for this step to work currently. It’s a good candidate for the community to improve to allow to run without this necessary. ---
