It works for me, using the v3 branch.

aqeeliqbal · March 28, 2018, 4:20pm

It used to work for me as well. I changed my mac and need to reinstall cocos setup.
one thing i observed is that on my new mac i installed python 3 few days ago. Now when i ran library build command it prompted an error that python2 in not install. then i installed python 2.7 as well. Now i have both python3 and python2, i wonder if it has something to do with this error?

slackmoehrle · March 29, 2018, 1:20am

It probably does. Which is default when you do python —version?

aqeeliqbal · March 29, 2018, 5:43am

its Python 2.7.14

slackmoehrle · March 29, 2018, 11:11am

I’d double check your setup, something is out of place. Tell me how yo obtained Cocos2d-x. .zip from our website or cloning our GitHub repo? What steps have you done so far?

aqeeliqbal · March 29, 2018, 3:00pm

I cloned it.

git clone <our repo>
cd <where ever you cloned the repo>
git submodule update --init
git submodule update
./download-deps.py
./setup.py 
source ~/.bash_profile

i followed these steps

slackmoehrle · March 29, 2018, 9:51pm

ok, those are my instructions. Everything should work.

Can you try the steps again and post your output for me. Let’s get you up and running.

aqeeliqbal · March 30, 2018, 7:35am

yup i follow your instructions since i was able to successfully build libs with your instructions

aqeeliqbal · March 30, 2018, 11:13am

I get error on this command

./download-deps.py

slackmoehrle · March 30, 2018, 7:24pm

try again, sometimes this step gives errors and then works. Let me know if it still fails.

aqeeliqbal · March 31, 2018, 9:55pm

tried it several times
getting errors again and again

You can wget this URL. When extracting be careful because the directory name is different. The contents of the .zip must do in the external directory.

aqeeliqbal · April 2, 2018, 5:46am

its working now.
Successfully built lib-cpp iOS

Thank you very much

slackmoehrle · April 2, 2018, 12:08pm

@aqeeliqbal You are welcome. I hope you enjoy writing your games. Please share with us when you have something playable.

aqeeliqbal · April 2, 2018, 3:59pm

yes i love games therefore i love making game
most of the game i create are cocosd2d-x based.
i love my app for kids : https://itunes.apple.com/us/app/kindergarten-prep/id985078379?mt=8 done in cocos2d-x and upcoming version include tensorflow for Nural networks and artificial intelligence.

slackmoehrle · April 2, 2018, 6:34pm

Can you share technical details about how you are using NN and AI in your app? How did you train? Are you using GPU’s to train?

aqeeliqbal · April 3, 2018, 8:01am

No, we train the model on laptop using python and tensorflow. Then we used that model in our app. currently its working on iOS only. we were able to successfully integrate everything using c++ and ios wrappers for iOS, but haven’t been able to run it on android yet.
