A simple way to compile the WebP encoder, since the vanilla makefiles fail on OSX

compile_webp_encoder.sh

#!/usr/bin/env bash

CC=clang
CCFLAGS="-c -I./libwebp-1.0.2"

function compile {
    local DIR=$1
    local NAME=$2
    for file in `ls $DIR/*.c`; do
        echo $file
        ${CC} ${CCFLAGS} $file
    done

    ar -rcs $NAME *.o
    echo "Wrote" $NAME
}


compile ./libwebp-1.0.2/src/enc libwebpencode.a
compile ./libwebp-1.0.2/src/dsp libwebpdsp.a
compile ./libwebp-1.0.2/src/utils libwebputils.a
