Hello all, # I am quite new to 64 bit Linux I am trying to build php-5.3.6 on CentOS 5.6, 64 bit. When I run ./configure under php-5.3.6, I get the following error: ----- Error ----- If configure fails try --with-jpeg-dir=<DIR> configure: error: libpng.(a|so) not found. ----- Error ----- Though libpng-devel and libjpeg-devel (both i386 and x64 rpms) are installed, it seems that configure could not find them. (I guess) I've fixed the errors by: 1. Adding /usr/lib64 to /etc/so.ld.conf, and 2. Specify jpeg lib dir that configure has to look: ./configure --with-jpeg-dir=/usr So, php 5.3.6 did compile fine but, curiously, I want to ask: 3. Why /usr/lib64 is not in ldconfig by default? 4. Why it is "--with-jpeg-dir=/usr" but not "--with-jpeg-dir=/usr/lib64"? BR, Nguyễn Vũ Hưng -------------- next part -------------- An HTML attachment was scrubbed...
