Question

我无法使用静态库构建共享库我从网上下载了一些代码，我试图将它作为我的android项目的lib，但是我无法为它创建共享库。

请在下面找到我的Android.mk文件

LOCAL_CFLAGS := -DFIXED_POINT -DEXPORT=""
LOCAL_MODULE := evrc
LOCAL_SHARED_LIBRARIES := dspmath code dsp_fx ttylib
include $(BUILD_SHARED_LIBRARY)

执行上面的make文件后，我得到了像这样的diff文件夹中的输出 1）上面的make文件位于$（PROJECT）/ jni文件夹中 2）Outpur文件是在$（PROJECT）/ obj / local / armeabi

如果你观察libevrc.so的大小，它是3.6K，小于静态库。请帮助我解决上述问题。如果您想了解更多信息，请与我们联系。

谢谢＆amp;问候，

Answer 1

我们必须使用LOCAL_WHOLE_STATIC_LIBRARIES 而不是 LOCAL_STATIC_LIBRARIES，以避免删除未使用的函数，以便将整个静态库加载到共享库中。

这是我从谷歌那里得到的基本答案。任何人如果知道，请添加更多信息。

Answer 2

[Dhanavel]：你是对的!!

我也遇到过类似的问题。将LOCAL_STATIC_LIBRARIES替换为LOCAL_WHOLE_STATIC_LIBRARIES后，将链接发生并最终生成。所以已生成。
