zlib, harsh compiler warnings and configure test

Question

I\'m trying to compile zlib from the command line, and I\'m getting this message when using -Wall -Wextra -Wconversion (full cross-compile script is below):

Answer 1

I had the exact same problem on a newly built machine, and I found the cause was that I didn't actually have the appropriate GNU C compilers installed (reference). Therefore it's complaining that the compiler is too harsh simply because there is no compiler.

Try running:

sudo apt-get install build-essential

and then try running your ./configure again.

Answer 2

My problem was:
cc1: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory

Search for details in configure.log.

Answer 3

mine was failing because it tried to use cc (non existent) instead of gcc
