hi i need help about custom build simulator cocos creator 3.8.0.
i have followed instruction on rebuild-the-native-engine-simulator
but when i hit command “gulp gen-simulator” it turns error.
it appear as “C:/Users/user/CocosProject/CocosEngine/native/simulator/generated/cocos/bindings/auto/jsb_physics_auto.cpp”,
and i don’t know why it can’t generate those file jsb_xxxxxxx
please asap
Hi, friend.
are you following the documentation below?
https://docs.cocos.com/creator/manual/en/advanced-topics/engine-customization.html#compilation
and get stuck on the compilation step?
yes @mr.kylin , I already follow all that step but in the end, I got stuck because of that error “can’t found custome-engine/native/simulator/generated/cocos/bindings/auto/jsb_physics_auto.cpp”.
And also I already see the source on the git and there is no such any file with name jsb_xxxxxxx
why do you need a custom build of cocos ?
“why do you need a custom build of cocos?”
I like this question. Because this is the point being open source game engine. Developer has access to develop new features that never made before such as full screen, aspect ratio fitter, 3d audio source and in my case, I wanna improve preview simulator.
Oh yeah that’s great I’m just interested on what changes you really need, I was also looking on making changes, for example I was also writing on How we can support Android TV games. while this works fine if you have a normal gamepad some inputs are missing for the Tv Controllers, I was able to map the missing Input Keys.
Whiles I agree with your right to make a custom build of the engine. The things you listed are all things I would like to see contributed to the core engine 
Hi @jamessimo , thanks for the kind words, Unfortunately the custom build returns error (you can see the detail above). I’ve follow all instruction on cocos web documentation but still gives same error. I still waiting for cocos team dev’s response.
Hi，sorry for my late reply.
which OS are you using, mac or windows? I will have a test when free.
windows 10
@westdragoneye I think you forgot to download external libs. The binding codes are generated when you build a native project, and it will use the tool that stored in external libs.
So could you please make sure:
ENGINE_ROOT/native/external/win64/bin/swig file, which includes the program to generate binding codesHi Mr @zhangxm , thank you for reply me.
I already download the external library sir. If I don’t there is no way I can run gulp command under its path.
this is my swig file. Am I got the right file(s) sir?
and this error I got when I hit command “gulp gen-simulator” on CMD:
[11:03:32] Using gulpfile ~\CocosProject\CocosEngine\native\gulpfile.js

Yep, it seems the swig program is correct. We will take a look.
Thanks sir
@westdragoneye Can you check if the directory is an empty folder or just jsb_physics_auto.cpp does not exist?
Have you tried deleting or backing up the ‘C:/Users/user/CocosProject/CocosEngine/native/simulator’ directory and trying again?
The directory is exist but jsb_physics_auto.cpp and other are not.
I have tried delete all things under simulator directory and rebuild again. But all efforts I made just give same issue. Even if I tried reinstall via github source (including external lib), it returns same error.
I am afraid there is missing step that doesn’t describe on cocos creator documentation to generate or download those file cpp (jsb_physics_auto.cpp and other).
None of them
