Audio / SFML Audio not statically linking - Observation

« on: July 04, 2024, 08:44:22 pm »

This is an observation, not a request for help.

CURRENT SETUP:

• Windows 11 - 64-Bit
• Compilers (i.e. GCC v14.1.0) and Libraries (i.e. SFML v2.6.1) are installed through MSYS2 (currently up to date)
• Using the CODE::BLOCKS IDE v20.03 (because I help beginners)

CURRENT COMPILER SETTINGS:
These settings are set in the "Project build options", not the "Global compiler settings" in Code::Blocks.

• [-m64]        Target x86_64
• [-Wall]       Enable all common compiler warnings
• [-O2]         Optimize for speed
• [-s]          Strip all symbols from binary
• [-std=c++23]  Follow the C++ language standard 23

#DEFINES:

• SFML_STATIC

LINKER SETTINGS:

• sfml-system-s
• sfml-audio.dll (Could not get the SFML-AUDIO-S library to work)
• winmm

SEARCH DIRECTORIES:

• COMPILER:  C:\msys64\ucrt64\include
• Linker:  C:\msys64\ucrt64\lib

This all works great on my computer, but when I move it to another Windows 11 machine, it requires the following DLL files to be in the same directory/folder as the executable:

• libFLAC.dll
• libgcc_s_seh-1.dll
• libogg-0.dll
• libopenal-1.dll
• libsfml-audio-2.dll
• libsfml-system-2.dll
• libstdc++-6.dll
• libvorbis-0.dll
• libvorbisenc-2.dll
• libvorbisfile-3.dll
• libwinpthread-1.dll

All these DLL files can be found in the C:\msys64\ucrt64\bin directory (if that is where MSYS2 was installed).

I have tried using [-static], [-static-libstdc++], and [-static] + [-static-libstdc++], but all the DLLs above are still required. As such, I removed [-static] and [-static-libstdc++] to keep the executable file size down to a bare minimum.

In the following source code, I used a modified version of the "PlayMusic()" function provided in the SFML "sound" example.

#include <SFML/System.hpp>
#include <SFML/Audio.hpp>
#include <string>
#include <iostream>


void
playMusic(const std::string& filename)
{
    const float FrameSpeed = 1.0f / 60.0f;

    sf::Music music;
    if (!music.openFromFile(filename)) return;

    std::cout << filename << ":\n"
              << " " << music.getDuration().asSeconds() << " seconds\n"
              << " " << music.getSampleRate()           << " samples / sec\n"
              << " " << music.getChannelCount()         << " channels\n";

    music.play();

    while (music.getStatus() == sf::Music::Playing)
    {
        sf::sleep(sf::seconds(FrameSpeed));

        std::cout << "\rPlaying... "
                  << music.getPlayingOffset().asSeconds()
                  << " sec        "
                  << std::flush;
    }

    std::cout << "\n\n";
}


int
main() {

    playMusic("music/Moonlight Hall.mp3");

}

 

No MINGW or VISUAL STUDIO was used or harmed in the making of the test demo or this post.
