Question

我正在尝试在Android上使用Boost.Coroutine2，但遇到了一些困难。

使用NDK r18时，从Hunter信息库编译Boost.Context失败，并显示以下“无效指令”错误（r19-beta1根本不起作用，原因是由于缺少cstddef标头伪造的--sysroot值）。

我定位到armeabi-v7a
我使用以下bjam参数：abi=aapcs architecture=arm binary-format=elf
定位arm64-v8a似乎可以工作，但是堆栈指针似乎有点混乱，因为它在某些情况下从调用asm实现的函数返回后就出现了段错误（在其他系统上不会发生）。我还无法确定哪些指令无效。

您知道为什么无法识别指令集吗？
