I want to link the library as shared (static linking has same trouble either).
I have:
- Windows 10
- Cmake 3.15
- Visual studio 19 (or Clion)
- Clang compiler (VS based, and from MSYS2 package)
What I do:
- Download SFML 2.5.1 for MinGW 64bit
- Unpack to D:/dev/SFML-2.5.1
- Create minimal test main.cpp:
#include <SFML/Graphics.hpp>
int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.draw(shape);
window.display();
}
return 0;
}
- Create CMakeLists.txt with following:
# ....
find_package(SFML 2.5 COMPONENTS system window network graphics audio REQUIRED)
if (NOT ${SFML_FOUND})
message(FATAL_ERROR "SFML couldn't be located")
endif()
set(SFML_LIBRARIES
sfml-graphics
sfml-network
sfml-window
sfml-audio
sfml-system)
# ...
add_executable(TrueEngine
${TRUEENGINE_CORE_SRCS})
target_link_libraries(TrueEngine
${SFML_LIBRARIES}
${LUA_LIBRARIES})
# ....
# P.S. find_package(...) found them
- Generate Visual Studio CMake project with following settings(1. VS clang, 2. Clang from MSYS2):
{
"name": "x64-Clang-Debug",
"generator": "Ninja",
"configurationType": "Debug",
"buildRoot": "${projectDir}\\out\\build\\${name}",
"installRoot": "${projectDir}\\out\\install\\${name}",

"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"inheritEnvironments": [ "clang_cl_x64" ],
"variables": []
},
{

"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"inheritEnvironments": [ "clang_cl_x64" ],
"variables": [
{
"name": "CMAKE_C_COMPILER",
"value": "C:/msys64/mingw64/bin/clang-cl.exe",

},
{
"name": "CMAKE_CXX_COMPILER",
"value": "C:/msys64/mingw64/bin/clang-cl.exe",
"type": "FILEPATH"
}
]
}
- Generate cmake cashe and build
After I have this errors from both compiler:

ninja: build stopped: subcommand failed.
Build All failed.
I see that libraries are not linked to the project, but I dont know why.
If I try to compile from a terminal, then all is fine, for example:

And it works.
What I do wrong in VS?
