单声道在Solaris上编译

Posted 2021-04-16

我正在尝试在Solaris 10上编译单声道。我已经尝试了从2.11.4到今天最新的5.xx版本的很多版本。但我总是失败。

我正在使用具有SPARC处理器的Sun-Fire-v240硬件。此外，OS版本是Oracle Solaris 10 1/13 s10s_u11wos_24a SPARC

我得到的问题是：

checking for PTHREAD_MUTEX_RECURSIVE... no
configure: error: Posix system lacks support for recursive mutexes

有没有办法为Solaris编译单声道，我一直在搜索这个问题，但我的情况没有工作结果。我对UNIX系统没那么好，所以我想我错过了一些东西......

谢谢。最诚挚的问候，奥尔罕。

答案

这似乎是一个两岁的Mono bug，Bug 31999 - C99 and XPG5 don't match on Solaris 10+：

checking for PTHREAD_MUTEX_RECURSIVE... no configure: error: Posix
system lacks support for recursive mutexes

哪个不对。在config.log中我找到了

此错误是configure.ac具有的事实

  CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE=500"

在Solaris 10及更高版本上，C99只能与XPG6 / _XOPEN_SOURCE = 600一起使用。完全省略_XOPEN_SOURCE定义不是一个选项，因为没有它，<sys/socket.h> struct msghdr缺少msg_flags成员。
