OTTO – Automate C/C++ CMake for Large Repositories

For large repository with many projects, dependencies and contributors, getting everything to work nicely is not an easy task. Standardization is the biggest issue. The idea behind `otto` is to get any project up and running with the tooling needed for a modern C or C++ codebase while requiring minimal cmake/makefile coding.

Code for `otto` is at github http://github.com/jainvishal/otto

Features in a nutshell:

  • Encapsulate complexities of cmake in module files
  • Very small and simple makefiles for end user projects
  • Handle external dependencies between projects using find_package
  • Out of source compilation
  • Support for installing both ‘release’ and ‘debug’ binaries and shared objects
  • Support for installation target. The binaries can be installed with the command make install.
  • Automatic version.h generated files.

DST does not influence UnixTime or Seconds since Epoch

Seconds since Epoc or Unixtime is ever increasing value and it remains stable (except for leap second). Daylight Savings changes does not affect it because Unixtime is based on UTC while DST is a local change applied to the timezone. So an application using Unixtime as a reference is not directly influenced by DST. Spent few hours today realizing this.
