We have two paid licenses. The first installation, on a 32 bit VPS went OK and is running smoothly, no hiccups for months. The second installation of lsws on a 64 bit dedicated server went fine, but PHP compilation is giving me grief. The server is CentOS 5.4, pretty bare. configure: error: libjpeg.(a|so) not found. Yum lists libjpeg: libjpeg.i386 6b-37 installed libjpeg.x86_64 6b-37 installed It's also in /usr/lib - where I added a further symlink to make sure it works: # ls -l /usr/lib/libj* lrwxrwxrwx 1 root root 17 Apr 27 16:58 /usr/lib/libjpeg.so -> libjpeg.so.62.0.0 lrwxrwxrwx 1 root root 17 Feb 15 13:31 /usr/lib/libjpeg.so.62 -> libjpeg.so.62.0.0 -rwxr-xr-x 1 root root 134268 Jan 6 2007 /usr/lib/libjpeg.so.62.0.0 This is the config I'm trying: That's with PHP 5.2.13 - I can't go up to 5.3.latest yet I also simply tried --with-jpeg-dir=/usr I actually need mailparse somehow in there too but will leave that for later. Why isn't it finding libjpeg when it's clearly there?
