大家好： 
    我买了细说PHP书来学习。在搭建环境时使用的是ubuntu系统 
编译libxml2的库是遇到如下错误， 
In function 'open', 
    inlined from 'xmlNanoHTTPSave__internal_alias' at nanohttp.c:1588:12: 
/usr/include/x86_64-linux-gnu/bits/fcntl2.h:51:24: error: call to '__open_missing_mode' declared with attribute error: open with O_CREAT in second argument needs 3 arguments 
make[2]: *** [nanohttp.lo] Error 1 
make[2]: Leaving directory `/home/waveshare/work/PHP/libxml2-2.6.30' 
make[1]: *** [all-recursive] Error 1 
make[1]: Leaving directory `/home/waveshare/work/PHP/libxml2-2.6.30' 
make: *** [all] Error 2 
求解决。。。。。。
