Title: could not build zlib in mingw
Status: Closed Type: Build Problem
Severity: Critical Priority: Immediate
Subsystem: Tcl Resolution: Fixed
Last Modified: 2015-03-30 23:54:47
Version Found In: 0.9.2
configure script of zlib 1.2.8 fails and says "Please use win32/Makefile.gcc instead." when $(uname -s) matches with MINGW* or mingw* by case statement of /bin/sh.

And default Makefile which will be used in this case also says same warnng, but make does not return error. So kitcreator script guesses wrong.

For example,  I succeeded to build zlib by following.
(awk line resolves another problem. Because Makefile.gcc resets CC and RC by self.)

    case $(uname -s 2> /dev/null) in
        MINGW* | mingw*)
            # use win32/Makefile.gcc instead.
            echo "Running: awk '{if($1~/^[RC]C$/&&$2~/^=/)$2="?"$2;print}' win32/Makefile.gcc > Makefile"
            awk '{if($1~/^[RC]C$/&&$2~/^=/)$2="?"$2;print}' win32/Makefile.gcc > Makefile

            echo "Running: ${MAKE:-make}"
            ${MAKE:-make} || exit 1

            echo "Running: BINARY_PATH=${INSTDIR}/bin INCLUDE_PATH=${INSTDIR}/include LIBRARY_PATH=${INSTDIR}/lib ${MAKE:-make} install"
            BINARY_PATH=${INSTDIR}/bin INCLUDE_PATH=${INSTDIR}/include LIBRARY_PATH=${INSTDIR}/lib ${MAKE:-make} install
            # If we are building for KitDLL, compile with '-fPIC'
            if [ "${KITTARGET}" = "kitdll" ]; then
                CFLAGS="${CFLAGS} -fPIC"
                export CFLAGS

            # We don't pass CONFIGUREEXTRA here, since this isn't a GNU autoconf
            # script and will puke
            echo "Running: ./configure --prefix=\"${INSTDIR}\" --libdir=\"${INSTDIR}/lib\" --static"
            ./configure --prefix="${INSTDIR}" --libdir="${INSTDIR}/lib" --static

            echo "Running: ${MAKE:-make}"
            ${MAKE:-make} || exit 1

            echo "Running: ${MAKE:-make} install"
            ${MAKE:-make} install

There is an issue with building zlib using MinGW.  Using a modified version of
your patch, I am able to build zlib.  However, the "awk" line caused problems
for me here (i.e. complaints about being unable to locate the "cc" command).

This issue should now be fixed on the 'winZlib128' branch.

Fixed on trunk via check-in [9ad5a7514f35a5a2].
