‘YYEMPTY’ undeclared (first use in this function); did you mean ‘YYCOPY’?

Question

I'm trying to build gas and gold linkers. But while building them I'm facing the following errors: I'm using gcc (Ubuntu 8.4.0-3ubuntu2) 8.4.0 to build it.

yyscript.c:2204:12: error: ‘YYEMPTY’ undeclared (first use in this function); did you mean ‘YYCOPY’?
   yychar = YYEMPTY; /* Cause a token to be read.  */
            ^~~~~~~
            YYCOPY
yyscript.c:2204:12: note: each undeclared identifier is reported only once for each function it appears in
yyscript.c:2320:17: error: ‘YYEOF’ undeclared (first use in this function); did you mean ‘SIZEOF’?
   if (yychar <= YYEOF)
                 ^~~~~
                 SIZEOF
yyscript.c:2326:22: error: ‘YYerror’ undeclared (first use in this function); did you mean ‘yyerror’?
   else if (yychar == YYerror)
                      ^~~~~~~
                      yyerror
yyscript.c:2332:16: error: ‘YYUNDEF’ undeclared (first use in this function); did you mean ‘YYENOMEM’?
       yychar = YYUNDEF;
                ^~~~~~~
                YYENOMEM

The source code of the build script is given below:

echo
echo -e "${BLUE}===================== build gas && gold ===========================${NC}"
echo

if [ ! -f ${PWD_PATH}/succeed/binutils ]; then
    wget -c 'https://ftp.gnu.org/gnu/binutils/binutils-2.30.tar.xz'
    tar xvJf binutils-2.30.tar.xz
    rm -r binutils-2.30/gas
    rm -r binutils-2.30/gold

    cp -r ${SRC_PATH}/binutils/gas-2.30 ${GAS_DIR}

    cp -r ${SRC_PATH}/binutils/gold-2.30 ${GOLD_DIR}

    cp $PROTODEF_DIR/$C_HDR $GAS_DIR

    cp $PROTODEF_DIR/$CC_HDR ${GOLD_DIR}/
    cp $PROTODEF_DIR/$PROTO_C ${GOLD_DIR}/

    eval "cd $PWD_PATH/binutils-2.30 && mkdir -p build && cd build"

    CFLAGS="`pkg-config --cflags 'libprotobuf-c >= 1.0.0'` -fcommon" LDFLAGS=`pkg-config --libs 'libprotobuf-c >= 1.0.0'` \
            ../configure --enable-gold --prefix=${PWD_PATH}/executable_binutils \
            --disable-werror --enable-shared \
             --enable-ld=default \
         --enable-plugins    \
             --enable-64-bit-bfd \
             --with-system-zlib \
            && make -j$(nproc)
            # && make install
    echo "done" > ${PWD_PATH}/succeed/binutils
fi

echo
echo -e "${GREEN}[*] build gas&&gold succeed!${NC}"

GAS_PATH=$PWD_PATH/binutils-2.30/build/gas/as-new
GOLD_PATH=$PWD_PATH/binutils-2.30/build/gold/ld-new

How can I fix this and what could be the source of this error?

Why are you removing the gas and gold src directories from the unpacked tarfile, and then replacing them with something else? Looks like those sources are corrupt. yyscript.c is a generated file, generated by bison, and in a clean build directory, those tokens should all be defined. — Cary Coutant, Apr 27 '23 at 19:58
