how to tell libpng, that zlib is installed

[Maaz]

zlib is installed, as
# cd /usr/src
# tar jxvf zlib-1.2.3.tar.bz2
# cd /usr/src/zlib-1.2.3
# mkdir /usr/local/zlib
# make clean
# ./configure --prefix=/usr/local/zlib
# make
# make install
no prblm but when I tried to install libpng, libpng complains that zlib not found

# tar jxvf libpng-1.2.16.tar.bz2
# cd /usr/local/libpng-1.2.16
# ./configure --prefix=/usr/local/libpng
.
.
.
checking for pow in -lm... yes
checking for zlibVersion in -lz... no
configure: error: zlib not installed
./configure --prefix=/usr/local/libpng
Now help me .. how can I let libpng know, that zlib is installed

Hi,

It might be that configure is falling over on the version of zlib that you're using rather than it not being installed...

What version of Linux are you using ?
Could you not grab binaries (RPMs) of the required libraries... they're fairly standard...

Hope this helps,

Regards,

Rob

I have zlib binary installed
# rpm -q zlib
zlib-1.2.3-15.2

Use:
--libdir=DIR

if zlibs are compiled or

--includedir=DIR

if source/header files are there.

As you have the RPM installed you shouldn't have needed to reinstall it from source. That will probably get things confused.

the issue resolved, when installed the zlib as
# ./configure
# make
# make install
i.e no arguments/parameters provide to "configure"
then successfully installed libpng ( http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1119589 )

Thanks Ivan Krastev for help.. yes it works too
./configure --prefix=/usr/local/libpng --libdir=/usr/local/zlib
