Trouble compiling on Android

slackmoehrle · February 26, 2017, 2:15am

I’m starting to create my own projects on Android. I’m having a bit of trouble compiling my project.

Cocos2d-x 3.14.1
using the pre-built libraries.

Here is my error:

Android NDK: /Users/slackmoehrle/Projects/cocos2d-x/cocos/audio/android/prebuilt-mk/Android.mk: Cannot find module with tag 'android-specific/tremolo/prebuilt-mk' in import path
Android NDK: Are you sure your NDK_MODULE_PATH variable is properly defined ?
Android NDK: The following directories were searched:

My Android.mk is:

LOCAL_PATH := $(call my-dir)

What mistake am I making?

lazydevx · February 26, 2017, 6:02am

ndk_module_path should not be in your bash file, it should be inside proj.android/build-cfg.json

like this

"ndk_module_path" :[
    "../cocos2d",
    "../cocos2d/cocos",
    "../cocos2d/external"
],

slackmoehrle · February 26, 2017, 7:27pm

Thanks. Mine looks like this:

{
    "ndk_module_path" :[
        "${COCOS_X_ROOT}",
        "${COCOS_X_ROOT}/cocos",
        "${COCOS_X_ROOT}/external"
    ],
    "copy_resources": [
        {
            "from": "../Resources",
            "to": ""
        }
    ]
}

but still getting the same error

lazydevx · February 27, 2017, 3:50am

try once after removing NDK_MODULE_PATH from bash_profile

slackmoehrle · February 27, 2017, 12:20pm

Sorry. I had done that and re-sourced. Still the same error.

energyy · February 27, 2017, 11:22pm

wow what happening:D that u trying to code something in coco2d-x? Is it for some kind tutorial/documentation?

which instruction u used to make project with prebuilt libraries, I can try to reproduce then to find what causing issue for you.

slackmoehrle · February 28, 2017, 12:33am

I’m working to write some docs on using pre-builts more and integrating them into YOUR applications, not just starting a project with cocos new. Right now, I cannot seem to compile a project with pre-builts.

zhangbin · February 28, 2017, 1:52am

@slackmoehrle
Are you using version 3.14.1? I just asked @dumganhar, the library tremolo is added to the v3 branch of cocos2d-x. But not in the version 3.14.1.

It’s a problem of command cocos gen-libs. I’ll fix it in v3 branch later.

slackmoehrle · February 28, 2017, 2:00am

@zhangbin I am using v3 branch and latest download-deps

So you are saying to switch to 3.14.1 branch and recompile gen-libs and try again?

zhangbin · February 28, 2017, 2:27am

As I know, the problem should not be happened in version 3.14.1. So, you can try it by the steps you mentioned.

zhangbin · March 1, 2017, 5:51am

@slackmoehrle I just solved the problem with this PR in v3 branch.

slackmoehrle · March 1, 2017, 12:05pm

I will test this today.

slackmoehrle · March 2, 2017, 1:54am

I still see this:


Android NDK: WARNING: APP_PLATFORM android-19 is larger than android:minSdkVersion 9 in ./AndroidManifest.xml

is it related? Any idea?

zhangbin · March 2, 2017, 3:54am

I found that you’re linking the module audio/android in your Android.mk. It’s the reason of your problem.

The module audio/android has already linked in the cocos/Android.mk.
When you’re using binary libraries of engine, the cocos/prebuilt-mk/Android.mk will be used ( instead of cocos/Android.mk). It will be using audio/android/prebuilt-mk/Android.mk.
Then there will be conflict with the audio/android/Android.mk configured in the Android.mk of your project.

Also, I think the following configurations in your project’s Android.mk will cause similar problems:

$(call import-module,Box2D)
$(call import-module,editor-support/cocosbuilder)
$(call import-module,editor-support/spine)
$(call import-module,editor-support/cocostudio)
$(call import-module,network)
$(call import-module,extensions)

zhangbin · March 2, 2017, 4:02am

The principle of the binary libraries usage is:

cocos gen-libs will generate the binary libraries & the corresponding Android.mk for each source code module. Because the Android.mk is different between source code & prebuilt libraries. (The prebuilt Android.mk will be gerenated in folder prebuilt-mk).
The project should link the prebuilt Android.mk to use the binary libraries of engine.

If you mixed prebuilt Android.mk & the source code Android.mk in the Android.mk of your project. The problem you mentioned will be occurred.

slackmoehrle · March 2, 2017, 4:50am

Can you provide a proper Android.mk for prebuilts? I guess I don’t know how to make one.

zhangbin · March 2, 2017, 5:47am

In fact, most of the libraries you configured in the Android.mk have already linked in cocos/Android.mk & cocos/prebuilt-mk/Android.mk.

So, what you should do is remove following lines from your Android.mk:

LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static
LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocosbuilder_static
LOCAL_WHOLE_STATIC_LIBRARIES += spine_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocostudio_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_network_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static


$(call import-module,audio/android)
$(call import-module,Box2D)
$(call import-module,editor-support/cocosbuilder)
$(call import-module,editor-support/spine)
$(call import-module,editor-support/cocostudio)
$(call import-module,network)
$(call import-module,extensions)

Hope it’s helpful!

slackmoehrle · March 2, 2017, 1:02pm

@zhangbin yup, very helpful! This will help our many users.

BPri · March 16, 2017, 10:38am

Hi!
The same problem.
Except I am trying to compile a new project without pre build mode.

Can you create a new project and compile it without pre build mode?

anieduard · March 21, 2017, 9:23pm

@slackmoehrle could you please me a bit please? I’ve already been struggling for like 2 days. So I’m also working with prebuilt libs, everything was working as expected on cocos2d-x-3.14 but when I updated to cocos2d-x-3.14.1 and I try to compile a Hello World application I get this error and I really couldn’t figure it out:
