trying to compile a utility in Openwrt and when pip-install is selected and zlib is linked to python I get this:

python has access to zlib headers and libraries

it seems that python-config --libs doesn't detect -lz and appending -lz fixes the problem

Hello sir! I got exactly same issue when compile some ipk in Openwrt. Would tell how to add "-lz" to python-config? I am not so familiar with Python coding. Thanks!

The report only shows output for 2.7. Is this issue really relevant to 3.x?
