Cygwin中交叉编译pthread_mutex_timedlock问题

今天编译Linux文件，遇到错误

pthread_mutex_timedlock was not declared in this scope

 

网上查了下：

Works fine on Linux (g++ -std=c++0x -lpthread with no additional defines).

However, this thread on Cygwin mailing list suggests that, at least as of 4.4, _GLIBCXX_HAS_GTHREADS was disabled by an autoconf test when building libstdc++ because pthread implementation of cygwin is missing pthread_mutex_timedlock. Perhaps MinGW has the same problem.

Also, this thread on comp.lang.c++.moderated says the same thing. Not supported by the library.

 

原来Cygwin中gcc gcc-4.4.3以上就开始不支持 pthread_mutex_timedlock

 

即使加上参数 -std=c++0x -lpthread （在Linux可以正常）也无用
