HarmonyOS 鸿蒙Next OpenHarmonyNext交叉编译，要编译protocolbuf的C代码生成.a静态库（需求是生成Aarch64架构）给到项目工程链接使用

编译脚本如下：

export CC=${OHOS_TOOLCHAIN}/bin/clang

export CXX=${OHOS_TOOLCHAIN}/bin/clang++

export AR=${OHOS_TOOLCHAIN}/bin/llvm-ar

export AS=${OHOS_TOOLCHAIN}/bin/llvm-as

export NM=${OHOS_TOOLCHAIN}/bin/llvm-nm

export STRIP=${OHOS_TOOLCHAIN}/bin/llvm-strip

export RANLIB=${OHOS_TOOLCHAIN}/bin/llvm-ranlib

export LD=${OHOS_TOOLCHAIN}/bin/ld.lld

#export LDFLAGS="--rtlib=compiler-rt -fuse-ld=lld"

export LDFLAGS="--rtlib=compiler-rt -L${OHOS_TOOLCHAIN}/lib -lc++ -fuse-ld=lld"

export CFLAGS="-fPIC --target=aarch64-linux-ohos -march=armv8-a -isystem ${OHOS_TOOLCHAIN}/include"

export CPPFLAGS="-fPIC --target=aarch64-linux-ohos -march=armv8-a -isystem ${OHOS_TOOLCHAIN}/include"

CURPWD=${PWD}

DISABLE="--disable-protoc"

# 编译 protobuf

PROTOBUF_BUILD_PATH=${CURPWD}/build/protobuf    # 输出路径

rm -fr ${PROTOBUF_NAME}

if [ ! -d ${PROTOBUF_NAME} ]; then # 如果 protobuf-3.6.1 不存在，则从压缩包中解压

  tar -xvf ${PROTOBUF_PACKAGE_PATH} -C ${CURPWD} ; wait

fi

cd ${PROTOBUF_NAME}

make clean 2>/dev/null

./configure --prefix=${PROTOBUF_BUILD_PATH} --host=arm CC="${CC}" CXX="${CXX}" CFLAGS="${CFLAGS}"

make

make install

cd ${CURPWD}

cd ${PROTOBUF_C_NAME}

make clean 2>/dev/null

./configure --prefix=${PROTOBUF_C_BUILD_PATH} --host=arm ${DISABLE} CC="${CC}" CXX="${CXX}" CFLAGS="${CFLAGS}"

make -v

make install

cd ${CURPWD}

# 编译 protobuf-c

export PKG_CONFIG_PATH=${PROTOBUF_BUILD_PATH}/lib/pkgconfig/ # 依赖项

编译报错如下
