Error compiling to run android

cocos2d-x
#1

I am now starting with coconuts and am trying to build my first project for android, however I followed the tutorial to compile the cpp-tests errors occurred, also tried to create a new project and compile and it is also happening the same errors as below, anyone know what can it be?

I use windows 8, cocos2d-x-3.2, and try to run android

It’s cause ssize_t is a different type than long int.

Are you sure, that you are using 3.2 Release, as it is declared as ssize_t tell(); with that version.

Update to 3.2 Release or change it by hand to ssize_t tell(); in CCBundleReader.h

#3

I downloaded yesterday, 15/09 file name cocos2d-x-3.2.zip, looked a post that talked the link below to use the ndk9, I downloaded it, but in another compilation error occurs.

Using ndk 9 the error occurs below

IQD Hello, thanks for your help :slight_smile:

And I did what you said and changed the CCBundleReader.h file for ssize_t tell ();

At compile time occurred some errors as below, but my application worked on android :slight_smile:

They fixed it in the github repo.
Guess I fixed it myself back then :smile:.

ndk 9 does not support c++_static as APP_STL.

In Application.mk set it to gnustl_static:

APP_STL := gnustl_static

Did you already change it, or did you compile with ndk 10?

Those are not errors, just warnings. So your code will compile fine.

#6

Hi,

Sorry, I’m compiling with ndk 10 :smile:

Now I can start my application, the next step is to use SQLite :slight_smile:

I was trying to use cocos2d JS, but it seems very complicated to use SQLite with him, I will become the cocos-x :slight_smile:

Thank you for your help :slight_smile:
