When using a modified zlib.pc, the warning goes away, but -lz is added back
by configure. The zlib.a is ignored, which is not the desired outcome. My
zlib.pc as the Libs: line modified as follows (libz.a has to come first but
does not take effect this way):
Libs: ${libdir}/libz.a -L${libdir} -L${sharedlibdir}
Instead of the original
Libs: -L${libdir} -L${sharedlibdir} -lz
Using make ZLIB_LIBS=/usr/coreutils/lib/libz.a does not change the behaviour
from the original post. I'm not sure this is the confirmation you are
looking for.
