C++: Undefine reference to functions defined in absl::lts_20230125 #12292
Description
What version of protobuf and what language are you using?
Version: v22.2
Language: C++
What operating system (Linux, Windows, ...) and version?
Windows 11
What runtime / compiler are you using (e.g., python version or gcc version)
gcc12.2.0 (mingw)
What did you do?
- Build and install protobuf from source code, and install it into the prefix of gcc.
- Write the following cmake project containing 3 files:
CMakeLists.txt,test.protoandmain.cpp. They are located in same dir.
#CMakeLists.txt
find_package(protobuf REQUIRED)
protobuf_generate_cpp(pb_src pb_hdr test.proto)
add_library(test_pb_lib ${pb_hdr} ${pb_src})
target_include_directories(test_pb_lib INTERFACE ${CMAKE_CURRENT_BINARY_DIR})
target_link_libraries(test_pb_lib PUBLIC protobuf::libprotobuf)
add_executable(test_pb main.cpp)
target_link_libraries(test_pb PRIVATE test_pb_lib)// test.proto
syntax = "proto3";
message test {
int32 msg = 1;
}// main.cpp
#include <iostream>
#include <test.pb.h>
int main(int, char **) {
::test test_msg;
std::cout << "Hello, world!\n";

Anything else we should know about your project / environment
Version of my cmake: 3.26.0-rc6
ABSL is not installed before I configure protobuf, so it must be installed together with protobuf.
The command used to clone protobuf repo:
git clone --recursive https://github.com/protocolbuffers/protobuf.gitThe command used to configure protobuf:
