Description
I'm trying to compile the base.zip
-like project, but using Clang (via a CMake toolchain file).
Compiling prints a linking warning :
C:/msys64/mingw64/lib/libMagnumGlfwApplication-d.a(GlfwApplication.cpp.obj): duplicate section ".rdata$_ZTSN6Magnum8Platform15GlfwApplicationE[_ZTSN6Magnum8Platform15GlfwApplicationE]" has different size.
Forcing the usage of LLVM's LLD with -fuse-ld=lld
gives me this error :
lld-link: error: duplicate symbol: typeinfo name for Magnum::Platform::GlfwApplication
>>> defined at CMakeFiles/appExec.dir/src/main.cpp.obj
>>> defined at libMagnumGlfwApplication-d.a(GlfwApplication.cpp.obj)
My toolchain file is as simple as :
list(APPEND CMAKE_PREFIX_PATH
${MINGW64_ROOT}
)
SET(CMAKE_BUILD_TYPE Debug)
SET (CMAKE_C_COMPILER "clang")
SET (CMAKE_CXX_COMPILER "clang++")
SET (CMAKE_C_FLAGS "-fuse-ld=lld")
SET (CMAKE_CXX_FLAGS ${CMAKE_C_FLAGS})
I've tried this using the official Magnum MSYS2 package, but also with the latest HEAD (local compilation of Corrade + Magnum). Same issue with both SDL2 and GLFW.
I've had absolutely no issue nor warnings with GNU tho.
Am I doing something wrong here ?
