ImageCreateFromJPEG.....no...... AAAARGH!

Hi all, I urgently need JPEG support in php4. I've latest version of libjpeg. I've compiled & installed latest version of gd lib. In the php dir I've done: ./configure ... --with-jpeg-dir=/usr/lib/ --with-png-lib -with-gd... but I always get this: checking for gdImageColorResolve in -lgd... yes checking for gdImageCreateFromPng in -lgd... yes checking for gdImageCreateFromGif in -lgd... no checking for libjpeg (needed by gd-1.8+)... yes checking for jpeg_read_header in -ljpeg... yes checking for gdImageCreateFromJpeg in -lgd... no It looks like it finds the libjpeg, but like if ImageCreateFromJpeg() isn't supported by my gd lib. Where am I failing. [yep, I've already deleted config.cache] Please, I really need this urgently. Best Regards, -- Federico Pomi http://www.Pomi.net
