我有一些在 OpenGL 中工作的代码,现在我想使用 ImGui 为我的应用程序制作 GUI。
ImGui::CreateContext();
当我试图通过包含一些头文件将ImGui 的一行代码复制到我的项目时ImGui
,它持续了一百个错误(可能是由于链接)。
我正在使用 Ubuntu 18,我使用 Makefile 来编译整个项目
我在包括以下内容时遇到的一些错误imgui.h
:
imgui/imgui.h:153:39: error: unknown type name ‘ImGuiInputTextCallbackData’; did you mean ‘ImGuiInputTextFlags’?
typedef int (*ImGuiInputTextCallback)(ImGuiInputTextCallbackData *data);
^~~~~~~~~~~~~~~~~~~~~~~~~~

当我运行一些提供的示例时,它们运行良好。但是,当尝试将我的项目与 imgui 的单行代码合并时,最终会出现上面显示的错误。
