 ## Linux Build Notes
 
-Libraries Needed:
+I've had a report that debian users (and some others) need these packages:
 
-* libxi-dev
-* libfreetype-dev
+- cmake
+- libx11-dev
+- libxrandr-dev
+- libxcursor-dev
+- libxi-dev
+- libglu1-mesa-dev
+- libudev-dev
+
+You may also need these:
+
+- libfreetype6-dev
+- libvorbis-dev
+- libflac-dev
+
+The problem with this is that I'm _also_ building these libraries and you shouldn't need these. If
+you look in the `wraps` directory you can see they're there.  I need to figure out why this is
+happening and kill it, but until then, install these too.
 
 It uses c++ so you may need to install a libg++ or libc++ for your system. Usually this is all you
 need:
 
 apt install build-essential
 
+Finally, I'm using at least GCC 14, so if you're older than that you'll have to upgrade.

 ## OSX Build Notes
 
 * Quite a bad experience. Need to install Python, cmake, meson, and ninja all which are in homebrew but if you don't use homebrew then this is a problem.
