Tracy Profiler supports MSVC, GCC, and clang. You will need to use a reasonably recent version of the compiler due to the C++11 requirement. The following platforms are confirmed to be working (this is not a complete list):
\begin{itemize}
\item Windows (x86, x64, ARM64)
\item Windows (x86, x64, ARM64\footnote{Requires \textbf{"OpenCL, OpenGL, and Vulkan Compatibility Pack"} from Microsoft Store.})
\item Linux (x86, x64, ARM, ARM64)
\item Android (ARM, ARM64, x86)
\item FreeBSD (x64)

Please don't ask about window decorations in Gnome. The current behavior is the intended behavior. Gnome does not want windows to have decorations, and Tracy respects that choice. If you find this problematic, use a desktop environment that actually listens to its users.
\end{bclogo}
\subsubsection{Windows on ARM}
Special considerations must be taken to run the Tracy server/profiler GUI on Windows on ARM.
Ensure that the \textbf{"OpenCL, OpenGL, and Vulkan Compatibility Pack"} is installed (from the Microsoft Store), otherwise the GUI will fail to open.
\subsubsection{Using an IDE}
The recommended development environment is Visual Studio Code\footnote{\url{https://code.visualstudio.com/}}. This is a cross-platform solution, so you always get the same experience, no matter what OS you are using.
