php 설치과정입니다.
./configure --with-apache=/usr/local/src/apache_1.3.19 --with-gd=/usr/local --with-mysql=/usr/local/mysql --with-config-
file-path=/usr/local/apache/conf --with-exec-dir=/usr/local/apache/bin --enable-track-vars=yes  이후
make에서 아래와 같은 error가 발생하는데 원인과 해결법을 알고싶습니다.
  gd.c: In function `php_if_imagegif':
gd.c:915: `gdImageGifCtx' undeclared (first use in this function)
gd.c:915: (Each undeclared identifier is reported only once
gd.c:915: for each function it appears in.)
