Pytorch C++ libs on Windows. ABI error

Hello,

I have just tried adding the libtorch libraries to my current project, as I want to start including it.
Unfortunately I am getting a most confusing error:

I am using Windows 10 and MinGW as my toolchains with gcc 6.3 installed. I have read about a similar issue on this forum regarding this ABI and (to my understanding) only gcc >= 4.9 works, which I should fulfill though.
My CmakeLists reads as follows and generates without errors:

cmake_minimum_required(VERSION 3.13)
project(Stratego_CPP)

set(CMAKE_CXX_STANDARD 17)

include_directories(${CMAKE_SOURCE_DIR}/libtorch/include)

set(CMAKE_PREFIX_PATH C:/Users/Michael/Documents/GitHub/Stratego_CPP/libtorch)

find_package(Torch REQUIRED)

set(COMMON_SOURCES utils.cpp GameState.cpp Game.cpp Piece.cpp
        Board.cpp GameDeclarations.cpp StrategoLogic.cpp Agent.cpp
        RandomSelector.h MCTS.cpp MCTS.h)

set(TARGET_SOURCES main.cpp)
add_executable(Stratego_CPP ${COMMON_SOURCES} ${TARGET_SOURCES})

target_link_libraries(Stratego_CPP "${TORCH_LIBRARIES}")

Can somebody help pointing me in the direction of why I am getting this error and how I can fix it?

Best regards,
Michael

I have exactly the same problem. I’ve tested on WLS, MinGW and Cygwin.

Sorry, On Windows, MSVC is the only supported compiler currently. If you want to build with MinGW, then you’ll need to build PyTorch from source using MinGW too.
