报告个android编译问题

Cocos2d-x
#1

编译环境：eclipse，ndk r10d, Cocos引擎 V1.0 Preview版本

问题描述：用ndk r10d编译出错，但是如果换成ndk r9d又能正常通过编译。可能有人会说用ndk r9d可以行了，但是3.3不是都说最好用r10c以上了吗？

另外我试过，用Cocos引擎 V1.0 Preview版本新创建出来的工程是能够用ndk r10d编译通过的，也就是说我用了某些2dx里面较少人用到的东西才会导致编译不过，但我也不知道具体是哪里的问题。所以只好来这反应了

下面是ndk r10d编译出错的错误信息

3.3rc2以后才建议r10c，之前都是建议使用r9d。

具体的原因看这个贴子的讨论：http://discuss.cocos2d-x.org/t/build-android-base-on-ndk-r10c/18543

为什么cocos 引擎 v1.0 preview不支持？

因为出cocos 引擎 v1.0 preview，Cocos2d-x的版本是rc0，所以内置的也是rc0。

#3

原来如此，那我提个建议吧，每次发布版本都写一下环境要求，从3.0到现在3.3rc2光ndk要求就变了好几遍，都有点晕了，也没地方可以查看

#4

好的，其实在官方仓库的README就有写明编译环境，使用什么版本的NDK。

#5

我不是要挑刺啊，只是希望大家用的都容易。
特意去看了readme，上面是这么写的：
Build Requirements

Mac OS X 10.7+, Xcode 5.1+
or Ubuntu 12.10+, CMake 2.6+
or Windows 7+, VS 2012+
Python 2.7.5
NDK r9d is required to build Android games
Windows Phone/Store 8.0 VS 2012+
Windows Phone/Store 8.1 VS 2013 Update 3+

可以看到，3.3版要求还是ndk r9d,但是发布公告上的却是这样写的：
We suggest you use NDK r10c or upper version, because it fixed some bugs that exist on Android 5.0.

可能是你们忘记更新readme了吧。

#6

:12::12::12:确实造成了混淆。

我让他们改下～！！！

#7

已更正！感谢反馈！～

#8

我想问下 cocos2d-x 2.2怎么适配Android 5？

#9

http://www.cocos2d-x.org/download/version 这个链接上下的v3.3 还是报错。我用的的是ndk-r10c.

错误描述：
jni/…/…/cocos2d/external/curl/prebuilt/android/armeabi/libcurl.a(sha512-armv4.o): requires unsupported dynamic reloc R_ARM_REL32; recompile with -fPIC

我把项目重新一步一步编译了下又好了。报错是我哪里设置有问题。
