无法使用静态库构建共享库

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，并试图将其作为我的 android 项目的库，但我无法为其创建共享库。

请在下面找到我的 Android.mk 文件

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

执行上述 make 文件后，我在 diff 文件夹中得到输出，如下所示
1) 上面的make文件在$(PROJECT)/jni文件夹中
2) 在 $(PROJECT)/obj/local/armeabi 中生成 Outpur 文件

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，请告诉我。

感谢和问候，

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。

这是我从谷歌得到的基本答案。如果有人知道，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 后发生链接并生成最终的 .so。
