install error, libz, ld, lz

Hi everyone,

I am trying to install the latest version of matplotlib from svn. However, after cd-ing into the matplotlib directory, and running “python setup.py install --prefix=${path}”, I get the following error:

/usr/bin/ld: skipping incompatible /usr/lib/libz.so when searching for -lz
/usr/bin/ld: skipping incompatible /usr/lib/libz.a when searching for -lz
/usr/bin/ld: skipping incompatible /usr/lib/libz.so when searching for -lz
/usr/bin/ld: skipping incompatible /usr/lib/libz.a when searching for -lz
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
error: command ‘c++’ failed with exit status 1

I don’t really understand what I need to do from this error message. Does it mean that I have to install ‘zlib’? I am using python 2.4.3, and numpy 1.2.1.

Thanks,

Jack

you need to install the development package (in the common sense, for
your pacakge manager) to be able to compile code that dinamically
links to libz. For example on Debian with libz-dev (provided by
zlib1g-dev).

Install a similar package for your distrivution and try to recompile matplotlib.
