php 5.2.17 소스 컴파일시 오류 (node.c: In function 'dom_canonicalization')

php 소스 컴파일시 아래와 같은 오류가 발생하는 경우가 있다. 

gcc 4.7 버전에서 아래와 같은 오류가 발생한다. 

/home/segio_php/php-5.2.17/ext/dom/node.c: In function ‘dom_canonicalization’:

/home/segio_php/php-5.2.17/ext/dom/node.c:1953:21: error: dereferencing pointer to incomplete type

/home/segio_php/php-5.2.17/ext/dom/node.c:1955:5: error: dereferencing pointer to incomplete type

이때는 아래와 같은 순서로 php 소스를 패치하면 오류가 사라진다. 

(소스 디렉토리에서)

# wget -O php.patch  https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt

# patch -p0 -b < php.patch

patching file ext/dom/node.c

Hunk #1 succeeded at 1950 (offset 55 lines).

patching file ext/dom/documenttype.c

Hunk #1 succeeded at 215 (offset 10 lines).

patching file ext/simplexml/simplexml.c

Hunk #1 succeeded at 1343 (offset -74 lines).

patch 명령어를 찾을 수 없다고 할 경우 yum -y install patch

위와 같이 패치를 적용한 후 컴파일을 하면 문제없이 진행된다.
