将非elf库链接到单个库时出错

标签： android c++ makefile android-ndk

我正在尝试构建一个有效的Android库，以便与名为ShiVa的游戏引擎一起使用，这也是问题所在：engine forum，photon cloud forum，但我想我是＆＃39已经达到了在stackoverflow中询问的要点，因为现在的主要错误是：

 [exec] jni/prebuilt/plugins/armeabi-v7a/PhotonCloudAPI.a(Plugin.o):Plugin.cpp:function _GLOBAL__sub_I_Plugin.cpp: error: undefined reference to 'std::ios_base::Init::Init()'

我在here中发现了这个错误，但是我没有使用任何string.h，只使用字符串和类似的库，好吧，这是 Shiva插件Makefile ：< / p>

这为我的Android应用程序项目生成了游戏引擎库（.a）。 啊，你可以看到Makefile使用obj / * .o文件，这些是使用AR -x从编译的光子库（.a）中提取的，因为rcs method不兼容，因为lib不是小精灵。

这是 Game Project Android.mk ，它使用由前一个makefile构建过程生成的PhotonCloudAPI_Android * .a文件（是的，它编译）。

我已经尝试了一切，我认为Shiva插件Makefile是错误的，也许我需要在链接中添加std libs？它编译，但然后它是使用编译的.a的游戏，无法编译。

1 个答案:

答案 0 :(得分：0)

我发现错误，从静态库中提取的对象包含对缺少的c ++库的引用。 我直接使用静态库作为.a并将第一个plugin.a编译为静态然后我使用它，将新的plugin.a再次链接到相同的库，作为游戏动态库的静态。
