Mac M1: Undefined symbols for architecture arm64 with manually compiled libs

[shvp]

I would really appreciate any help with that. That code is simple as it can be

#include <SFML/Window.hpp>

int main()
{
    sf::Window window(sf::VideoMode(800, 600), "My window");
}

The setup is VS Code & C/C++ Extension v1.9.5

g++ --version
Apple clang version 13.1.6 (clang-1316.0.21.2)
Target: arm64-apple-darwin21.2.0

Full error message goes like this:

I tried to follow this topic, but as original poster I still can't figure this out: https://en.sfml-dev.org/forums/index.php?topic=27867.0

I've compiled libs as it was suggested there. Here you can see that they are actually arm64:

~ % cd /Users/DG/cppurgatory/SFML_repo/lib
DG@MBP-SHVP lib % file libsfml-audio.3.0.0.dylib
libsfml-audio.3.0.0.dylib: Mach-O 64-bit dynamically linked shared library arm64

Running this tasks.json:

            "command": "/usr/bin/g++",
            "args": [
                "-fdiagnostics-color=always",
                "-I",
                "/usr/local/include",
                "-L",
                "/Users/DG/cppurgatory/SFML_repo/lib",
                "-g",
                "${workspaceFolder}/*.cpp",
                "-o",
                "${workspaceFolder}/bin/run",
                "-std=c++17",
            ],

With c_cpp_properties.json configuration:

            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",
                "/Users/DG/cppurgatory/SFML_repo/lib",
                "/usr/local/include"
            ],
            "defines": [],
            "macFrameworkPath": ["/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks"],
            "compilerPath": "/usr/bin/g++",
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "macos-gcc-arm64",
            "forcedInclude": []
       

Any thoughts? Been struggling for two days already. I really want write some actual code already

Looks like you're trying to link 64-bits SFML libraries while compiling for arm64.
Make sure to either use the snapshot builds for arm64 or when building SFML yourself, to set the architecture to arm64.

when building SFML yourself, to set the architecture to arm64.

So dylib I built showing:

DG@MBP-SHVP lib % file libsfml-audio.3.0.0.dylib
libsfml-audio.3.0.0.dylib: Mach-O 64-bit dynamically linked shared library arm64

I'll try snapshot anyways. Thanks!

Ah, I might have misunderstood the file message.

Looking at the issued command, you're never actually linking SFML, plus you're using g++ and not clang / AppleClang.

/usr/bin/g++ -fdiagnostics-color=always -I /usr/local/include -L /Users/DG/cppurgatory/SFML_repo/lib -g /Users/DG/cppurgatory/helloworld/*.cpp -o /Users/DG/cppurgatory/helloworld/bin/run -std=c++17

See the g++ usage here and the lack of -lsfml-xyz flags.

I really appreciate your help! I managed to create a window.
So I'm still using g++. What does a trick:

 
                ...
                "-L",
                "/usr/local/lib",
                "-lsfml-system",
                "-lsfml-window",
                "-lsfml-graphics",
                "-lsfml-network",
                "-lsfml-audio",
                 ...

+ moved FLAC, freestyle, freestyle folders and other ext dependencies from arm64 snapshot you posted to /Library/Framework
Cheers!
