clang++ link asbl lib failed

[WittonBell]

Description / Steps to reproduce the issue

1. create main.cpp:

#include <absl/log/log.h>

int main(int, char**){
    LOG(INFO) << (unsigned long long)1;
}

2. create `CMakeLists.txt":

cmake_minimum_required(VERSION 3.5.0)
project(t VERSION 0.1.0 LANGUAGES C CXX)

find_package(absl REQUIRED)
add_executable(t main.cpp)
target_link_libraries(t PUBLIC absl_log_internal_message)

3. run cmake -DCMAKE_CXX_COMPILER=clang++ . in mingw64 terminal
4. run cmake --build .
   it report:

ld: CMakeFiles/t.dir/main.cpp.obj:main.cpp:(.text$_ZN4absl12lts_2024072212log_internal10LogMessagelsEy[_ZN4absl12lts_2024072212log_internal10LogMessagelsEy]+0x19): undefined reference to `_ZN4absl12lts_2024072212log_internal10LogMessagelsIyTnNSt9ena

If I use clang++ in clang64 environment the program compiles fine. Probably, there are some difference in abseil-cpp package in gcc and clang based environment.

You can also try adding -fuse-ld=lld to link options and -stdlib=libc++ to compile options.

@oltolm It does not take effect, also has the issue.

Then the mingw64 version is not binary compatible with clang and you should use the clang64 environment like Biswa96 said.
