Cocos android c++_static compile error

cocos2d-x C++
1

I tried switching to Cocos with prebuilt framework. It works fine for VS2013 but for android it wont compile. I have narrowed the problem down to using c++_static in my Application.mk like so:
APP_STL := c++_static

I tried this on a brand new Cocos project. I tried with frameworks 3.5 and 3.7, and ndk10d and ndk10e. However it works fine when using cocos2d-x source.

Here is the start of what the compiler spits out:

Anyone have an idea whats going on here?

Bump.

I know I’m not the only one using APL_STL := c++_static to compile for Android, but maybe I’m the only one trying it with the prebuilt framework?

Any insight into this problem would be greatly appreciated. I would really like to switch to using Cocos with prebuilt framework but right now this is the only thing holding me back.

Currently I’ve tried to use
APP_STL := c++_static

for

Cocos2d-x/tools/simulator/frameworks/runtime-src/proj.android/jni/Application.mk

Trying to generate prebuilt libs using command:
cocos gen-libs -p android --ap android-19 --app-abi x86:armeabi-v7a

and got errors while generating prebuilt libs:

error: '::fsetpos' has not been declared
 using ::fsetpos;

@zhangxm why build for android still using deprecated gcc? Why APP_STL := gnustl_static ?
@slackmoehrle who else also actually can answer this question?
It’s really highly recommended to update cocos2d-x to not deprecated things…
Currently I can’t compile cocos2d-x prebuilt libs for android because of that… but I waned to create a tutorial how to use them… I can’t…
I’m using all latest NDK and android studio 3.0, but tools folder replaced with old one(know solution).

@anon98020523 Let me ask someone to look at this.

I think i mentioned why not using c++_static a few times, can refer to this issue too: https://github.com/cocos2d/cocos2d-x/issues/18286.

7

Your link is just for issues, which one?
Anyway gnu is bad and deprecated and can be even removed later as I understand.

8

Sorry, the link is: https://github.com/cocos2d/cocos2d-x/issues/18286. Yep, it will be removed, but c++_static is not stable now.

Aha, yes, Gnu will be removed so you should start use static beforw to test and get ready code changes.

@zhangxm also in newnon cocos2d-x repo for SpriteBuilderX we don’t have any problems like in bug you posted.
So thats something with your code. I don’t know what was fixed and when I don’t know.
Anyway - you definitely should use c++_static, thats future and if you don’t get ready for that now, you will be in a past…

But i can not use not stable lib in engine, developers will use it in real product. But yep, we should prepare for it, how about creating a new branch named android_c++_static to test it.

11

And we used it for production games for a long time already.

12

It can not make sure that it doesn’t have issues.

13

You are only one person who supporting engine currently?

14

@slackmoehrle @dumganhar and new new guy are supporting cocos2d-x now.

Edit: other developers mostly focus on Creator, and will sync some bug fix from cocos2d-x-lite to cocos2d-x if needed.

15

Ok I see… but that’s sadly.
