1.88 error: "'DC': undeclared identifier" in imgui.cpp

[ItsNovaAndCrap]

Whenever I try to build, it says that DC isn't declared! I am using TheCherno's fork of ImGui, I would make an issue over there but it doesn't have an issues or discussions page! I am using ImGui 1.88.

Sorry this doesn't constitute a viable support request, you are providing zero context.

sry, i am trying to create a game engine with thecherno's tutorial. I currently just started implementing imgui and got that error when I tried to build.

This doesn't really add any details that couldn't already be inferred from your main question. Before we can even guess what might be wrong with your environment we need way more detail.

Ideally you should be providing full error message, line numbers, the contents of that line (or the specific Git commit you're on or a permalink to the line on GitHub's web interface), what platform you're building for, and what compiler+build system you're using.

Gotcha

I am building for x64 platforms.
Here's the full error and the lines that this error is coming from:

Severity Code	Description	                Project	File	                                Line	Suppression State
Error	C2065	'DC': undeclared identifier	ImGui	D:\dev\Mist\Mist\vendor\ImGui\imgui.cpp	3839

Error	C2065	'DC': undeclared identifier	ImGui	D:\dev\Mist\Mist\vendor\ImGui\imgui.cpp	3841	

and here are the lines that the errors are coming from:

3839 |     for (int i = 0; i < DC.Layouts.Data.Size; i++)

3841 |        ImGuiLayout* layout = (ImGuiLayout*)DC.Layouts.Data[i].val_p;

as for the build system, i'm using the default one that comes with visual studio 2022 (msvc)

These errors are coming from changes made to the fork of Dear ImGui that you're using. You're going to have to take it up with @TheCherno.

Compare ImGui::SetActiveID between vanilla Dear ImGui docking with TheCherno's Dear ImGui fork.

Found out whats wrong! before the DC you need to put window->

So the end result looks like this

for (int i = 0; i < window->DC.Layouts.Data.Size; i++)

   ImGuiLayout* layout = (ImGuiLayout*)window->DC.Layouts.Data[i].val_p;
