EDIT: Your dll file isn't even recognized as a valid DLL by the tools that I have to dump dll information.
EDIT 2: The first 1536 bytes (= exactly 3 * 512 bytes) in your DLL are all 0-bytes, so the file looks corrupted. Have you tried deleting the file and letting your cmake project generate it again?

I tried deleting it and copying it with the CMake script, but I still encountered the same error. So, I attempted to locate the file where it's being copied from, but I couldn't find anything. Is it possible that the file is not in the folder and CMake creates it?

Copying the tgui-d.dll from TGUI 1.2.0 works in VS Code and directly from the directory. Thank you very much.

Thank you. I tried reinstalling it, and here's the zip archive. I included the entire build directory to ensure you have everything. The 'CMakeLists.txt' is provided below.

0xc000012f seems to mean that the "Microsoft Visual C++ Redistributable" isn't installed, which is a bit weird in this case. To run any software that was build with Visual Studio, you need to have the redistributable installed for that Visual Studio version. It raises a question though: what code is built with Visual C++? You are building with MinGW, the precompiled SFML libraries were build with MinGW, and TGUI is being build together with your project and also with the MinGW compiler.

It seems like it, but that is super confusing.

They are already in there. My CMake script copies all SFML and MinGW .dll files into the build directory while configuring the project.

The command copied or created the .dll, but the application still crashes. When attempting to start the .exe in the build directory, I now receive an error stating that the file doesn't exist or is not suitable for Windows. Error code: 0xc000012f

In VS Code, the application crashes with the error "Command executed, took 85ms and failed (Exit code 1).

It's possible, but it's hard to say if you don't actually get an error message. Are the sfml and dll files placed next to the exe?

The SFML .dll files are present, but when attempting to run the .exe directly from the build directory, I receive an error stating that the tgui-d.dll is not found. Where can I find it?

Apologies for bothering you once more. Despite the initial joy of successfully compiling the program, it appears to crash every time I attempt to run it, without any error messages. Could I be overlooking something, such as copying .dll files or a similar requirement?

is that something I should consider in general or is it more something for debugging?

It's only for debugging.
The higher the number, the faster the project will build (as the number indicates how many source files can be compiled simultaneously). At least as long as the number doesn't exceed the amount of CPU threads your processor has (a higher number will work but won't make it faster) and as long as you have sufficient RAM (which becomes important for very high values).
Setting it to 1 means that all operations are done sequentially and nothing is done in parallel. This makes building much slower, but then the logs will properly show you which step is being executed when the error happens.

Good to know. I believe I'll need to delve deeper into CMake to fully utilize it. Thank you very much for your patience and guidance. Everything is functioning now.

The library name passed to "target_link_libraries" should be either "TGUI::TGUI" (recommended)

I've managed to compile this file now.

}

I now have an issue with the example for the SFML backend, encountering an undefined reference to the bool runExample(tgui::BackendGui& gui) function.

The cmake command that is being executed has "-j 6" in it. Is this something you can change yourself? The log output would have been more clear if you ran it with "-j 1" (which you should only do when investigating an issue, as usually you do want to build with more threads). Now it builds your project and the gui builder at the same time so it prints both outputs interleaved and it isn't clear that the error is about your project and not the gui builder.

There is a way, is that something I should consider in general or is it more something for debugging?

I deeply appreciate your assistance thus far. Nevertheless, I've encountered a snag with the GUI builder.

I apologize for any confusion. I am new to CMake, so my knowledge is somewhat limited. I have only used CMake for incorporating SFML into two projects, and you can see how I did that in my CMakeLists.txt files, which compile without any issues. I referred to this blog post (https://www.ics.com/blog/find-and-link-libraries-cmake) to integrate the TGUI library, so I'm having a bit of trouble following your steps.

The source directory is being set to the "TGUI" subdirectory, but the build directory is the one from your project? That would mean that it is trying to build TGUI and your own cmake script isn't even being executed.

I tried something different. Here is the orignale Cmakelists.txt:

cmake_minimum_required(VERSION 3.17)

# Füge das ausführbare Ziel hinzu und verlinke ImGui
add_executable(AutoBackupScript ${SOURCES})

set(TGUI_DIR "C:/Users/luka-/OneDrive/Desktop/AutoBackupScript2/TGUI/cmake")
find_package(TGUI 1 REQUIRED)

target_link_libraries(AutoBackupScript PRIVATE TGUI)

# Suche und verlinke SFML

find_package(SFML COMPONENTS system window graphics network audio REQUIRED)
if (SFML_FOUND)
    target_link_libraries(AutoBackupScript PRIVATE sfml-system sfml-window sfml-graphics sfml-network sfml-audio)

but i encountered a similar problem.

Thank you for your time and assistance.

The set(SFML_DIR "c:/SFML/lib/cmake/SFML") should be sufficient when placed before the find_package or add_subdirectory line.

TGUI tries to find SFML with "find_package(SFML 2 CONFIG COMPONENTS graphics REQUIRED)".

- Which files does c:/SFML/lib/cmake/SFML contain?
- Which SFML version is located in c:/SFML?
- Did you build SFML yourself or download a precompiled version from their website?
- Which MinGW version are you using?

Thank you for the prompt response and assistance.

1. alle the cmake files
   - SFMLConfig.cmake
   - SFMLConfigDependencies.cmake
   - SFMLConfigVersion.cmake
   - SFMLSharedTargets.cmake
   - SFMLSharedTargets-debug.cmake
   - SFMLSharedTargets-release.cmake
   - SFMLStaticTargets.cmake
   - SFMLStaticTargets-debug.cmake
   - SFMLStaticTargets-release.cmake
2. SFML 2.6.0 is installed
3. I downloaded a precompiled version from their website.
4. I am using GCC 13.1.0 MinGW 64-bit

Hello, I'm currently trying to integrate TGUI into my SFML project. I'm using CMake and VS Code, but I've encountered a problem where TGUI can't find SFML. I have the error message ready here, which mentions setting the SFML_DIR, but I'm not sure exactly where to do that. Any help would be greatly appreciated.
