Bake

Bake is an eductaional clone of GNU Make written in C. The aim of the project is to learn more about C, build systems, tokenization, parsing, graph theory, parallel computation, and more!

Features

• Execute all targets in a Bakefile
• Specify a single target to execute
• Detect and report cycles in the dependency graph
• Raise an error when target is not defined
• Avoid re-executing targets that are up to date
• Concurrent target execution (using pthread)

TODO

• Test concurrent modifications to the file system (somehow xD)
• Implement a thread pool
• Add support for variables
• Dockerize bake

Installing Dependencies

Bake is only supported on Linux. It has been tested on Ubuntu 20.04 LTS.

To compile Bake, you will need the following:

• GNU Make (unironically)
• GCC (GNU Compiler Collection)
• pcre (package for Perl Compatible Regular Expressions)
  • To install: sudo apt update && sudo apt install libpcre3 libpcre3-dev

Compiling

• To compile Bake, run make in the root directory of the project. The following binaries will be created in the build directory:
  • bake executable.
  • some test binaries named build/test_<testname>
• To generate debug symbols when compiling bake, run make DEBUG=1.
• Run make clean in the root directory of the project to remove all build artifacts.

Testing

• Run make run-tests in the root directory of the project to run the test suite.
• To run a particular test, run make run-test-<testname> (without the .c extension).

Running

• To run Bake, run ./build/bake. Note that this will execute Bakefile in the root of the project.
