Have you tried searching for those function names in the imgui folders (using "find in files" of your search editor)

The first error says:

"C:/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:\Users\user\AppData\Local\Temp\ccnPetga.o:imgui_demo.cpp:(.text+0x1656b): undefined reference to ImGui::TableSetupColumn(char const*, int, float, unsigned int)' C:/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:\Users\user\AppData\Local\Temp\ccnPetga.o:imgui_demo.cpp:(.text+0x1657a): undefined reference to ImGui::TableSetupScrollFreeze(int, int)'"

If i search for TableSetupColumn in imgui folders:

https://github.com/search?q=repo%3Aocornut%2Fimgui%20TableSetupColumn&type=code

The result is:

Thanks a lot, it move my progress a little)
But there is one more problem

And i've got this problem:

and it's look a little strange. 'cause it seems like imgui.cpp don't see the imgui_table functions, but it was build right above it...

This seems like your different source/include files are from different version of dear imgui.

ocornut Aug 2, 2024

I'm not sure I understand why people feel the urge to copy and move files around and create this sorts of issue for themselves.
It's clear from your paths that you are not using an unmodified imgui/ repository. If you are not familiar with C++ building tools it may be better to use unmodified libraries rather than move things around, in my opinion.

I don't know, sorry for that) i think it's just the classical problem of someone who are new to something and just trying to solve the problem and explore the way to programming things by himself, but instead making more issues)
Thanks a lot for your advice, i changed the version of every part of the project, and i'm not sure, but it seems that "imgui issues" has gone, and it seems like a progress, 'cause the building progress changed from 7% to 70))
