MIPS - ASM的编译
MIPS - ASM的编译
提问于 2015-02-19 16:40:43
我试图在我的新Ci20上编译Plex家庭影院，但我遇到了一些构建错误，我认为这些错误与ASM有关，我不知道是否有人能够提供任何帮助。

问题是没有设置DISABLE_MATHUTILS_ASM_ROUND_INT，因此，由于没有MIPS版本，编译器正在尝试编译默认的x86 asm版本，该版本显然无法工作。
仔细观察，您可能应该扩展从第35行开始的条件，以检测MIPS并禁用asm代码。或者，作为一种快速攻击，您只需将一个无条件的#define DISABLE_MATHUTILS_ASM_ROUND_INT与#define DISABLE_MATHUTILS_ASM_TRUNCATE_INT放在第50行，以使其编译即可。
代码的逻辑似乎有缺陷，它们应该只在他们有asm代码的体系结构上特别启用asm代码，而不是相反。
