Build wasm(libprotobuf.a failed with undefined symbol(std::__2::__basic_string_common<true>::__throw_length_error() const)

[coolg92003]

I Use make file Makefile.base to build below 4 files failed with below errors, any suggestions? 4 files: HFEDHttpScreen.h HFEDHttpScreen.cc Below two files are build by (protoc --proto_path=${SRC_DIR} --cpp_out=${DST_DIR} ${SRC_DIR}/HFEDHttpScreenMsg.proto) /usr/local/bin/protoc --version libprotoc 3.9.1 HFEDHttpScreenMsg.pb.h HFEDHttpScreenMsg.pb.cc

When trigger to build wasm file with below command em++ --no-entry -s EXPORTED_FUNCTIONS=['_malloc'] -sLLD_REPORT_UNDEFINED -Wl,--trace-symbol=ZNKSt3220vector_base_commonILb1EE20throw_length_errorEv -std=c++17 -O3 -flto -Ic++-noexcept -I${PROXY_WASM_CPP_SDK} -I${PB_DIR} -I/usr/local/include --js-library ${PROXY_WASM_CPP_SDK}/proxy_wasm_intrinsics.js $.cc ${PROXY_WASM_CPP_SDK}/proxy_wasm_intrinsics.pb.cc ${PB_DIR}/HFEDHttpScreenMsg.pb.cc ${CPP_CONTEXT_LIB} ${PROXY_WASM_CPP_SDK}/libprotobuf.a -o $.wasm

[coolg92003]

em++ version is 3.1.23 Also run command "em++ --clear-cache" and no any improvement

[coolg92003]

do this make file again, then works now cat Makefile_pb CPP_API ?= .
