+### Ubuntu 24.04 and Newer Linux Versions
+
+Some newer Ubuntu versions have reported issues with older compiler versions. For Ubuntu 24.04 and
+other newer Linux distros, it is recommended to build with gcc-13 or clang-18. This can be installed as follows:
+
+```zsh
+# if using clang
+sudo apt-get install clang-18
+# if using g++ or building with libstdc++
+# sudo apt-get install gcc-13 g++-13 cpp-13
+# if building with libc++
+sudo apt-get install libc++-18-dev libc++abi-18-dev
+```
+
+Note that installing libc++-18 via apt will uninstall all other libc++ versions.
+
+Additionally, some newer Linux distros no longer package clang-format-12, and newer clang-format versions are
+not backwards compatible. To build from source, you'll need to do the following:
+
+```zsh
+sudo apt-get install ninja-build cmake
+git clone --depth 1 --branch llvmorg-12.0.1 https://github.com/llvm/llvm-project.git
+cd llvm-project
+sed -i "17i #include <stdint.h>" llvm/include/llvm/Support/Signals.h
