我一直在尝试使用 MinGW-w64 编译 XZ Utils,并在尝试运行 make
时之后./configure
ing,我收到错误 sigset_t
未知。
XZ Utils 版本是 5.2.3,我的 MinGW-w64 是 x86_64-7.2.0-posix-seh-rt_v5-rv1
.

我检查了signal.h
对于 sigset_t
使用gcc -E - <<< "#include <signal.h>" | grep sigset_t
但什么也没找到。现在我一直想知道这是否是 MinGW 的限制,如果是,是否有办法解决它。
最佳答案
https://github.com/Alexpux/mingw-w64/blob/master/mingw-w64-headers/crt/sys/types.h#L110
#ifdef _POSIX
typedef _sigset_t sigset_t;
#endif
看来只有在定义了 _POSIX 时才定义它。它也在 sys/types.h 与 signal.h 中...
