復制代碼

flw

所以 Perl 程序員也要懂 C 語言，懂系統(tǒng)調(diào)用。遇到這種問題直接人擋殺人佛擋殺佛，逢山開路遇水搭橋，該改什么直接 vim 一下就改了。

flw

/root/.cpan/build/IO-Epoll-0.02-KvJKWF/blib/arch/auto/IO/Epoll/Epoll.so: undefined symbol: epoll_pwait at /usr/local/perl5.12/lib/5.12.3/x86_64-linux-thread-multi/DynaLoader.pm line 200.

這個應該是錯誤的根源。
看起來像是 configure 的問題。

moxnet

這個在我的FreeBSD上編譯也通不過.

這個東西依賴系統(tǒng), 不知道你的系統(tǒng)是否滿足他的要求?

在他的readme中說:

The epoll(4) subsystem is a new, (currently) Linux-specific variant of
poll(2).  It is designed to offer O(1) scalability over large numbers of
watched file descriptors.  You will need at least version 2.5.44 of Linux
to use this module, and you might need to upgrade your C library.

epoll_pwait 需要 2.6.19 以上的內(nèi)核才能支持，目前 RHEL/CentOS 5.6 以下版本都是 2.6.18，你直接用 force 強制安裝就可以了，不會有問題的，我們目前就是這樣用的。

但是要注意，程序里面不要調(diào)用 epoll_pwait 就可以了！
