Hello everyone,
I'm having issue while trying to build a minimal c++ grpc application using
vcpkg as package manager and cmake to build the app.
The issue happens during link with an unresolved external:
grpc.lib(uri.cc.obj) : error LNK2019: unresolved external symbol
__std_find_first_of_trivial_pos_1 referenced in function "unsigned __int64
__cdecl std::_Find_first_of_pos_vectorized<char,char>(char const *
const,unsigned __int64,char const * const,unsigned __int64)"
(??$_Find_first_of_pos_vectorized@DD@std@@YA_KQEBD_K01@Z)
It happens if I try to build a simple proto file.
This is my cmakelists.txt:
cmake_minimum_required(VERSION 3.22)
project(it-dms-injection)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED True)
if(MSVC)
add_definitions(-D_WIN32_WINNT=0x0600)
endif()
find_package(Protobuf CONFIG REQUIRED)
find_package(grpc CONFIG REQUIRED)
add_executable(it-dms-injection
proto/route_guide.proto
main.cpp
)
target_include_directories(it-dms-injection PRIVATE
${CMAKE_CURRENT_BINARY_DIR})
set(PROTO_FILES
proto/route_guide.proto
)
protobuf_generate(
TARGET it-dms-injection
LANGUAGE cpp
PROTOS ${PROTO_FILES}
IMPORT_DIRS proto
)
# Custom command to generate gRPC sources
foreach(proto ${PROTO_FILES})
get_filename_component(proto_name ${proto} NAME_WE)
set(grpc_src "${CMAKE_CURRENT_BINARY_DIR}/${proto_name}.grpc.pb.cc")
set(grpc_hdr "${CMAKE_CURRENT_BINARY_DIR}/${proto_name}.grpc.pb.h")
add_custom_command(
OUTPUT ${grpc_src} ${grpc_hdr}
COMMAND protobuf::protoc
ARGS --grpc_out=${CMAKE_CURRENT_BINARY_DIR}
--cpp_out=${CMAKE_CURRENT_BINARY_DIR}
-I ${CMAKE_CURRENT_SOURCE_DIR}/proto
--plugin=protoc-gen-grpc=$<TARGET_FILE:gRPC::grpc_cpp_plugin>
${CMAKE_CURRENT_SOURCE_DIR}/${proto} # FIXED LINE
DEPENDS ${proto}
)
list(APPEND GRPC_SRCS ${grpc_src})
list(APPEND GRPC_HDRS ${grpc_hdr})
endforeach()
target_sources(it-dms-injection PRIVATE ${GRPC_SRCS} ${GRPC_HDRS})
target_link_libraries(it-dms-injection PRIVATE
protobuf::libprotobuf
gRPC::gpr
gRPC::grpc
gRPC::grpc++
gRPC::grpc++_alts
)
and I'm using VS 2022 version 17.14.0.
Does any of you is experiencing a similar issue?
Thanks,
Guglielmo
