No Incremental Build for NDK (Cocos2Dx sources are always compiling)

cocos2d-x C++
#1

I have used the famous tutorial “Cocos2D-X for iOS and Android: Getting Started” and everything works now, except building with NDK ALWAYS compiles ALL files (so it’s not incremental). I mean I would accept my project files to be compiled always, but it’s rather tedious to compile all Cocos2d-x sources! Does everyone have the same experience? Actually Cocos2dx is already split in a separate library, so it’s problem with NDK (using r8c)?

I have the same issue and I’d like to understand why it recompiles everything every time and how to avoid it.

#3

Could you post the Tutorial link, platform, and method to compile please?

I work on Linux, with NDK 8 and work fine. First time compile cocos2d-x lib, and my code, the rest only my changes in code.

Check your compiling-script, look for “ndk-build” and be sure that ~~B option is NOT active.~~B always force recompilation.

Running on Win32 using Eclips & Cygwin

I did not manage to compile using build_native.sh under cygwin, so I created my own build_native.cmd which calls build-ndk.cmd in the same way build_native.sh does. But I can see there is no any special options given to compiler.

#5

What part of the code are you changing? What is the log result on compilation?

#6

I change nothing. Just call “build” again and it compiles all over again ;(

#7

To cross check; I’ve just managed to compile using cygwin+build_native.sh - the same result - it’s recompiling all the sources each time.

#8

This is a known issue for NDK r8c on Mac OS X.
I have reported this to Google before release but these smart guys ignored it, then realized their error after r8c release, since many people complained about it.
They merged a fix into AOSP project a few days after.

See here : https://groups.google.com/forum/?fromgroups=#!topic/android-ndk/EFA21mVVqH0
The patch is to change a single line 289 in build/core/definitions.mk from

$1: $$(__ndk_file_dir)

to

$1: | $$(__ndk_file_dir)

Romain, thank you very much.

Merci also from my side! It works now as expected!

Thanks!

Thanks. I had the same problem on Windows 8.
