Question

需要帮助调试共享库加载失败的原因。安卓NDK

cor*_*bin 5 android shared-libraries android-ndk

我正在尝试使用以下方法加载共享库： System.loadLibrary("sharedC"); sharedC 依赖于其他 2 个共享库 sharedA 和 sharedB，所有三个都是使用独立工具链制作的，并作为预构建的共享库包含在内。我在 sharedC 之前加载了 sharedA 和 sharedB 并且我不知道其他依赖项。但是当我尝试加载 sharedC 时，我得到了一个 SEGV。当我运行 strace 时，这就是我得到的：

writev(3, [{"\3", 1}, {"dalvikvm\0", 9}, {"Trying to load lib /data/data/com.exa

关于出了什么问题的任何想法？

好的，调试堆栈跟踪对我来说是新的，但请继续并告诉我我是否做错了？

有趣的是，似乎我是 SEGV 发生在我的代码之外？看起来它发生在 libgnustl_shared.so 中。

所以这是我的堆栈跟踪：

所以，我不知道现在该怎么办。我没有创建 libgnustl_shared.so，它只是 ndk 的一部分。在此之前，我已经加载了一些其他共享库。这发生在加载依赖于其他共享库和 libgnustl_shared.so 的最后一个库时，我首先加载了它。

正确调试此问题还需要哪些其他信息？

Update 2

为了更好地描述我的项目，我正在加载 6 个共享库。

第一个是 libgnustl_shared.so，它加载良好。下一个是 libpcre.so。这是一个预构建的共享库。它加载良好。这是它的自述：
