ACE在ubuntu上的编译错误

Question

ACE/TAO-5.6.9 gcc version 5.4.0 Ubuntu 16.04.2

执行以下命令时：
$ tar xjvf ACE-5.6.9.tar.bz2
$ cd ACE_wrappers
$ mkdir build
$ cd build
$ ../configure --prefix=/usr/local
$ make

出现错误：
../../ace/Dev_Poll_Reactor.cpp: In member function 'int ACE_Dev_Poll_Reactor::dispatch_io_event(ACE_Dev_Poll_Reactor::Token_Guard&)':
../../ace/Dev_Poll_Reactor.cpp:1216:41: error: cannot bind packed field 'pfds->epoll_event::events' to '__uint32_t& {aka unsigned int&}'
__uint32_t &revents = pfds->events;

怎么解决？

Answer 1

这个应该是/usr/include/linux的头文件引用问题。改成eventpool.h就可以了。并且由于字节对齐，引用也会出现问题，可以先赋值给一个uint32_t 使用完之后，再将值重新赋予结构体。
