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
