Build Status

OS Examples

Synopsis

A number of example programs to accompany the os.cs.luc.edu lecture notes for the Operating Systems course at Loyola University Chicago.

Recent Developments

  • Updated CMake build process. All examples are driven by a top-level CMakeLists.txt. CMake is pretty awesome. I just don't have the time to write Makefiles by hand, and I never enjoyed working with autoconf.

  • Establish foundation for using GoogleTest.

  • Modular structure to allow various examples to be standalone programs, possibly with internal library dependencies.

  • Many new examples with pthreads.

Debian/Linux/GNU Systems

OS X via Homebrew

We only provide limited support for OS X and Homebrew at this time. The core examples from https://os.cs.luc.edu work. However, some of the newer examples rely on some GNU-specific (and sometimes GNU-only) features that don't seem to have a clear equivalent on OS X (even via Homebrew). I'm still working on it.

Nevertheless, if you want to try, do the following:

  • git clone https://github.com/SoftwareSystemsLaboratory/systems-code-examples
  • brew install cmake gcc@11
  • Install GoogleTest using instructions at https://github.com/SoftwareSystemsLaboratory/googletest-mva.
  • cd systems-code-examples
  • mkdir build
  • cd build
  • cmake -DCMAKE_C_COMPILER=$(which gcc-11) -DCMAKE_CXX_COMPILER=$(which g++-11) ..
  • make

Hopefully, by end of the Fall semester, I will be able to get the 5 pesky examples to build/run on OS X. It's not a matter of if but when.
