C++ utilities

Common C++ classes and routines used by my applications such as argument parser, IO and conversion utilities.


The library utilizes:

  • parsing command-line arguments
  • dealing with dates and times
  • conversion of primitive data types to byte-buffers and vice versa (litte-endian and big-endian)
  • common string conversions/operations, eg.
  • split, join, find and replace
  • conversion from number to string and vice verca
  • encoding/decoding base-64
  • IO
  • reading/writing primitive data types of various sizes (little-endian and big-endian)
  • reading/writing terminated strings and size-prefixed strings
  • reading/writing INI files
  • reading bitwise
  • building with CMake by providing some modules and templates

Build instructions


Build-only dependencies

  • C++ compiler supporting C++11 (I've tested GNU g++, Clang and mingw-w64 yet.)
  • CMake (I've only tested 3.5.1 so far.)
  • cppunit for unit tests (optional)
  • Doxygen for API documentation (optional)

Runtime dependencies

  • The c++utilities library itself only needs the C/C++ standard library.
  • For dependencies of my other projects check the of these projects.

How to build

Just run:

cd "path/to/build/directory"
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/final/install/location" "path/to/projectdirectory"
make check # build and run unit tests (optional)
make c++utilities_apidoc # build API documentation (optional)
make DESTDIR="/temporary/install/location" install

General notes

  • The make option -j can be used for concurrent compilation.
  • Building with qmake is not supported anymore.

Building for Windows

Building for Windows with Mingw-w64 cross compiler can be utilized using a small cmake wrapper from Fedora:

${_arch}-cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/final/install/location" "path/to/source/directory"
make DESTDIR="/temporary/install/location" install-mingw-w64-strip
  • To create the *.ico file for the application icon ffmpeg/avconv is required.
  • The target install-mingw-w64-strip in the example will only install files suitable for creating a cross-compiler package and additionally strip the binaries.

Development builds

During development I find it useful to build all required projects (for instace c++utilities, qtutilities, tagparser and tageditor) as one big project.

This can be easily achieved by using CMakes add_subdirectory() function. For project files see the repository subdirs.

For a debug build, just use -DCMAKE_BUILD_TYPE=Debug.

Creating Arch Linux package

The repository PKGBUILDs contains files for building Arch Linux packages. PKGBUILD files to build for Windows using the Mingw-w64 compiler are also included.


  • There is a workaround for GCC Bug 66145 provided in io/catchiofailure.h.
