Hello, We are facing an issue while installing Postgres-9.0.1 on CentOS-5.
Below is the error we are encountering - ./configure -- output checking for inflate in -lz... no configure: error: zlib library not found If you have zlib already installed, see config.log for details on the failure. It is possible the compiler isn't looking in the proper directory. Use --without-zlib to disable zlib support. Inside the config.log, below is what we see - configure:8204: checking for inflate in -lz configure:8239: gcc -o conftest -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv -D_GNU_SOURCE conftest.c -lz -lreadline -ltermcap -lcrypt -ldl -lm >&5 /usr/bin/ld: skipping incompatible /usr/lib/libz.a when searching for -lz /usr/bin/ld: cannot find -lz Zlib rpms are installed and below is the rpm -qa output - [root@localhost postgresql-9.0.1]# rpm -qa | grep zlib zlib-1.2.3-4.el5 jzlib-1.0.7-4jpp.1 zlib-devel-1.2.3-4.el5 zlib-1.2.3-3 Thanks VB
