unable to compile python 2.3 with zlib support

Question

For an legacy application (plone 2.0.5) i need python 2.3. The compile succeeds but the zlib module is not built. The zlib.h file is present in /usr/include

I am at a loss here because later versions of python compile without problems with zlib support.

I tried so far: configure --prefix=path/to/my/install --zlib=/usr/include

and with a zlib compiled from scratch in my home dir

configure --prefix=path/to/my/install --zlib=/home/my-user/include configure --prefix=path/to/my/install --zlib=/home/my-user/

also configure --prefix=path/to/my/install --zlib=/home/my-user/

between make runs i always do a: make clean so no remnants of previous compiles should interfere

Edit: Klynton looked into this and found the solution in the comments at this post: Configure and compile Python with Zlib

The trick is after you run configure, you need to uncomment zlib in Modules/Setup in the Python source tree, eg:

tar zxf Python-2.3.7.tgz
cd Python-2.3.7
./configure --prefix=$HOME/python
sed -i "s/^#zlib/zlib/g" Modules/Setup
make 
make install

That said, if you still want to build against a locally-installed zlib, then my original answer below should work.

I just tested installing Python 2.3 with zlib support on one of our CentOS 6 servers and was able to do it as follows (installing everything into ~/python):

mkdir ~/src ~/python
cd ~/src
wget http://zlib.net/zlib-1.2.5.tar.bz2
tar xjf zlib-1.2.5.tar.bz2
cd zlib-1.2.5
./configure --prefix=$HOME/python
make
make install
cd ..
wget http://www.python.org/ftp/python/2.3.7/Python-2.3.7.tgz
tar zxf Python-2.3.7.tgz
cd Python-2.3.7
./configure --prefix=$HOME/python --with-zlib=$HOME/python/include/
make
make install

A quick test after the build shows that zlib is available and working:

$ ~/python/bin/python -c "import zlib;x = zlib.compress('foo');print zlib.decompress(x)"
foo

Hope that helps!

thanks that works. Just for the record:

the trick seems to be to install zlib and python in the SAME directory (same --prefix)

so configure zlib:

./configure --prefix=/path/to/my/python


make

make install

and python:

./configure --prefix=/path/to/my/python --with-zlib=/path/to/my/python/include


make
make test

make install

note the --with-zlib=/path/to/my/python/include has include at the end of the path
