Clarification regarding make of build.lx

Respected, I have tried building the file inside genode-13.08 but was not able to build it. I have installed all necessary files.

I am getting this error- /usr/local/genode-gcc/bin/genode-x86-ar: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory make[2]: *** [platform.lib.a] Error 127 make[1]: *** [platform.lib] Error 2 make: *** [gen_deps_and_build_targets] Error 2

How should I rectify this error?

Thank you! Bulusu.
