Re: how to compile postgresql with other version of openssl?

# ./configure CFLAGS="-I/usr/openssl-0.9.8zg/include"
LDFLAGS="-L/usr/openssl-0.9.8zg/lib" --with-openssl

configure: error:
Could not execute a simple test program. This may be a problem
related to locating shared libraries. Check the file 'config.log'
for the exact reason.

# tail config.log
...
#define HAVE_GETHOSTBYNAME_R 1
#define GETPWUID_R_5ARG 1

configure: exit 1

It does compile without a problem when used without CFLAGS and LDFLAGS
but against system lib /lib64/libssl.so.6

# LDFLAGS="-L/usr/openssl-0.9.8zg/lib" ./configure --with-openssl
checking test program... failed
configure: error:

# tail config.log

#define HAVE_GETHOSTBYNAME_R 1
#define GETPWUID_R_5ARG 1

configure: exit 1

setting LDFLAGS to openssl lib dir causes postgresql ./configure to
fail without real explanation. A bug?
