==== Follow-on Questions ====
* Does g++ support each of these sanitizers?
* What other tools should I research besides gdb, lldb, valgrind, UBSAN, ASAN, TSAN, and MSAN?
* Are there tools other than sanitizers and debuggers I should know about?
* Are there obsolete tools I should ignore?
* Are there books that cover C++ topics beyond writing C++? How about how-to guides? (I'll be searching for these next, but do you happen to know any particularly useful and easy to read?
* Crash dumps and crash dump tools. I don't know much about them. What good resources on this topic are there for Linux, Windows, and Mac?
 
 
 
 
 
==== Background ====
I'm about to start going through the list above for myself. It may take a while.
 
I'm currently involved in a project with about half a million existing lines of C++ code and want to know what tools I need to work in this environment properly. The application has multi-threaded parts.
 
I can do basic g++, Debug, DebWithRelInfo, and Release builds using cmake or a pre-defined build script and step through code line-by-line with the gdb in VSCode, but want to become familiar with gdb at the command line.
 
I want to come up to speed with clang and lldb in vscode.
 
[[/stackoverflow.com/questions/63978029/setup-lldb-debugging-with-cpp-extension-in-vscode-linux|https://stackoverflow.com/questions/63978029/setup-lldb-debugging-with-cpp-extension-in-vscode-linux]]
 
== Other Thoughts ==
 
I need to familiarize myself with other tools available, learn how to enable particular tools in a build, and learn how to use the tool's output.
 
I want to learn to use tools like UBSAN, ASAN, TSAN, and MSAN effectively and how to switch from g++ to clang when appropriate. I want to learn what tools other than the sanitizers and debuggers above are available.
 
There's no such thing as free beer! Someone pays for flightgear cloud infrastructure that I personallly benefit from.  So I contribute a little at:
 
<nowiki>https://liberapay.com/t3r</nowiki>
 
Currently working on:
 
Git Worktrees with download_and_compile.sh  (done & working)
 
Web Socket Refactor & Fix. 
 
OSM (Open Street Map) Scenery Build (on hold)
 
Goals (Maybe)
 
*Download Scenery from Current Scenery Developers
*Build Scripts for Scenery Land Class, Elevation, and OSM processing
*Understand the underlying formats in Flightgear Scenery
*Understand the processing of Scenery data between tiles in the build process and the running simulator
*Assist Scenery Developers with technical support.
*full explanation of the advantages and disadvantages of the worktree approach.
