Zlib error

Hello, I'm trying to install php-4.3.1 on an Apache Server 1.3.12, My problem is that even if configure doesn't give me errors or warnings on zlib, The make install commang result on an error telling me that : "zlib.lo is not recognised : File truncated". I've read that ldconfig command is used to rebuil library, I tried it on my zlib directory. And nothing happened (ldconfig seemes to work only in .so files not ..lo). My Configure command is : ./configure --with-oci8 --with-gd --with-zlib (or --with-zlib-dir=/path/to/zlib/) --with-apxs=path/to/apxs I've made several tryal, removing config.cache betwwene each, but no one have worked. Does someonge already have this problem or can someone help me. Thanks in advance Mazzucco Vincent Elève Ingénieur Stagiaire Système d'Information Email : vincent.mazzucco@storaenso.com
