android - Oculus SDK / Android NDK 链接错误 1 - “您的意思是”与使用的符号相同

Question

我正在尝试链接到我根据 Android 指令为 ARM 交叉编译的一些静态库。我能够加载一些变量，但正在努力解决其中一个变量：

ld: error: undefined symbol: ACE_Time_Value::ACE_Time_Value(long, long)

我已经尝试了很多东西，但似乎没有任何效果。对于我做错了什么，我将不胜感激任何建议或帮助。

这与不匹配的 ABI 问题有关。我重新编译了静态库，强制它们使用特定的 ABI 并正确链接。感谢 Reddit 上的 u/Xeverous。
