C++ ：Interix 信号
如何在Interix平台上编译/使用信号？我无法编译它，因为 Interix 似乎不符合 POSIX，至少在 signal.h 的实现中是如此。
如果有人找到了一种方法来解决这个问题并允许带有信号的代码在 Interix 上编译，请告诉我如何做！
谢谢。
详细信息：
使用 C、C++ 编写的旧版软件，基于 Linux 和 Interix（适用于 Win XP）构建。
仅在 Interix 上，编译期间出现以下错误；在添加 pthread 和 signal 代码后，Linux 上不存在这种情况。无法在没有信号的情况下使用 pthreads，因为与 Xmotif 冲突（编译但在运行时崩溃）。
由于结构差异而导致的错误：
`struct siginfo' has no member named `si_value'
aggregate `sigval val' has incomplete type and cannot be defined
`struct sigaction' has no member named `sa_sigaction'
由于未声明而导致的错误：
`sigqueue' undeclared
`SA_NODEFER' undeclared
`SA_SIGINFO' undeclared

How to compile/ use signals on the Interix platform? I am unable to get it to compile because Interix appears to be non-POSIX compliant, at least in its implementation of signal.h.
If anyone has found a way to work around this and allow code with signals to compile on Interix, please do let me know how!
Thanks.
Details:
Legacy software in C, C++, and is built on Linux and Interix (for Win XP).
Am getting the following errors during compilation, on Interix only; not on Linux, after adding pthread and signal code. Cannot use pthreads without signals because conflicts with Xmotif (compiles but crashes at run time).
errors due to struct differences:
`struct siginfo' has no member named `si_value'
aggregate `sigval val' has incomplete type and cannot be defined
`struct sigaction' has no member named `sa_sigaction'
errors due to undeclared:
`sigqueue' undeclared
`SA_NODEFER' undeclared
`SA_SIGINFO' undeclared

根据POSIX规范，
struct sigaction没有成员sa_sigaction，它有sa_handler。POSIX：http://pubs.opengroup.org/onlinepubs/009695399/函数/sigaction.html
Interix：http://www.suacommunity.com/man/2/sigaction.2.html
Interix 符合 POSIX 标准，您的代码是移植不是。
请注意，Linux 可以与
sa_handler一起使用。不过，您也许可以使用正确的
#DEFINE来使其工作。According to the POSIX specification, there
struct sigactionhas no membersa_sigaction, it hassa_handler.POSIX: http://pubs.opengroup.org/onlinepubs/009695399/functions/sigaction.html
Interix: http://www.suacommunity.com/man/2/sigaction.2.html
Interix is POSIX compliant in the case, the code you are porting is not.
Note that Linux can be made to work with
sa_handler.You may be able to get it work using the correct
#DEFINEs though.请参阅 Interix 手册页 和上面的开放组链接。
您可以用 sa_handler 替换 si_sigaction。
See the Interix man page and the open group link above.
You can possibly replace the si_sigaction with sa_handler.
