Hello, Questions with regards to compiling PHP to support GD with JPEG on 64-bit CentOS 5.5. 1) Specifying folder for jpeg library When I execute the following command, am I saying the full path to libdir is at /usr/source/lib64? ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source --with-libdir=lib64 Should I have done the following instead? ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source/lib64 2) After copying the compiled JPEG libraries to the the lib64 directory, PHP is still unable to call the GD functions (ie ImageCreateFromJpeg) properly. Once I've done the following. ./configure --enable-shared make make install I have the following files installed. Meanwhile the /usr/local/lib64 directory doesn't have these files. Despite copying the whole set to /usr/local/lib64, the above configure command still doesn't work. /usr/local/lib/libjpeg.a /usr/local/lib/libjpeg.la /usr/local/lib/libjpeg.so -> libjpeg.so.8.0.2 /usr/local/lib/libjpeg.so.8 -> libjpeg.so.8.0.2 /usr/local/lib/libjpeg.so.8.0.2 The following displays a blank page on my Firefox. <?php header('Content-Type: image/jpeg'); $image_file_path = '/usr/local/apache2/htdocs/image.jpg'; $image_file_path"; $im = @ImageCreateFromJpeg($image_file_path)"; echo "$im"; imagejpeg($im); echo "End: imagedestroy($im)"; ?>
