在 MIPS 上编译 - ASM

Question

我正在尝试在我的新 Ci20 上编译 Plex 家庭影院，但我遇到了一些我认为与 ASM 相关的构建错误，我对 ASM 一无所知我想知道是否有人能够提供任何帮助。

构建错误

非常感谢任何指导！

问题是 DISABLE_MATHUTILS_ASM_ROUND_INT 没有设置，所以，由于没有 MIPS 版本，编译器试图编译默认的 x86 asm 版本，这显然是行不通的。

仔细观察，您可能应该扩展从第 35 行开始的条件以检测您的 MIPS 并禁用 asm 代码。或者，作为一种快速破解，您可以在第 50 行将无条件 #define DISABLE_MATHUTILS_ASM_ROUND_INT 和 #define DISABLE_MATHUTILS_ASM_TRUNCATE_INT 一起粘贴以使其编译。

代码的逻辑似乎有缺陷，他们应该专门只在他们有 asm 代码的架构上启用 asm 代码，而不是相反...
