[Mapserver-users] RH8 and GD

[woodbri at swoodbridge.com]

John,

I just tried this on my system and it works fine. I'm using the RH8

rpm -q libpng
rpm -q libpng-devel
rpm -q freetype

I have installed gd-2.0.11 in /usr/local
and here is my build script for php-4.3.1

make clean
rm -f config.cache
./configure \
  --enable-force-cgi-redirect \
  --enable-discard-path \
  --with-config-file-path=/etc/httpd/ \
  --with-gd=/usr/local \
  --with-jpeg-dir \
  --with-png-dir \
  --with-zlib-dir \
  --with-free-type-dir \
  --without-tiff \
  --with-pdflib \
  --with-mysql \
  --with-regex=system \
  --with-ming \
  --enable-dbase \
  --enable-dbx \
  --enable-versioning

echo ----------------------------------------------
echo   make
echo   make install
echo   cp sapi/cgi/php /var/www/cgi-bin
echo   cp php.ini-dist /etc/httpd/php.ini
echo   change extension_dir = /etc/httpd/php_mods/
echo ----------------------------------------------


Hope this helps,
  -Steve W.
