Linking Error only with tgui::Textures

[LeeDev]

I am currently working on a project using TGUI with SFML in Visual Studio and have encountered a linker error that I'm unable to resolve. The error occurs specifically when I try to use the tgui::Texture class. Other components of TGUI seem to work fine in my project, but any attempt to use tgui::Texture results in a linker error.

LNK2001: unresolved external symbol "private: static bool tgui::Texture::m_defaultSmooth" (?m_defaultSmooth@Texture@tgui@@0_NA)


Project Setup:

IDE: Visual Studio 2022
TGUI Version: TGUI 1.1.0
SFML Version: 2.6.1
Build Configuration: Debug
Platform: Win32

I have checked that my project is set up according to the TGUI documentation:

The TGUI library is correctly linked in the project settings.
I am using the correct build configuration (Debug/Release) for both TGUI and SFML.
The include and library directories are properly set in Visual Studio.
I have tried the following steps to troubleshoot the issue:

Rechecked all linker settings in Visual Studio.
Verified that there are no multiple definitions of TGUI symbols.
Rebuilt the TGUI library to ensure it matches my project settings.
Created a minimal test case where I only use tgui::Texture.
Despite these efforts, the linker error persists. It's puzzling that this issue is specific to tgui::Texture and does not affect other TGUI components.

I would greatly appreciate any insights or suggestions on how to resolve this issue. Has anyone else encountered a similar problem, or can anyone spot something I might be missing in my setup?

Thank you in advance for your help!

I'm assuming you would also get a linking error when using e.g. tgui::Color::Black in your code?

While I haven't seen this issue with TGUI yet, I remember seeing similar issues before with SFML (where people got linking errors only for the "static" variables). I think the cause might have been mixing libraries like shared vs static ones.

Can you maybe share the .vcxproj file of your project so that I can check if I can see something unusual about it?

Yeah, no problem. Thanks for being so active just in general.

You are defining SMFL_STATIC (which even has a typo) and TGUI_STATIC, but you are linking to the dynamic libraries (i.e. the ones that don't end have "-s" in the name). So you should remove SMFL_STATIC and TGUI_STATIC from the PreprocessorDefinitions.

[LeeDev]

Oh duh. I remember seeing that in the docs and thought I skipped it, but apparently not. I didn't know all of that information was in the vcxproj either.

Thanks for the help, and keep up the great work!
