fluxkit: Frank's lightweight portable components

A C++ Developer's Swiss-Army Knife

fluxkit provides a small set of libraries and tools for Unix system programming. The entire toolkit is fully self-contained without any external dependencies other than a gcc compatible compiler and a standard C++ runtime. Development happens mostly on Linux and OpenBSD, but design goal is to support any modern operating system which implements the core POSIX API.


  • fully garbage collected
  • highlevel data countainers, without iterators
  • powerful string processing and pattern matching
  • designed for mulithreading from ground up
  • fast compile times
  • transparent API: full access to low-level system primitives
  • batteries included:
    • easy to use build system (fluxmake)
    • built-in webserver (fluxnode)
      • compatible and fast (HTTP 1.1, memory mapped I/O)
      • easy to extend
    • powerful text search and replace (fluxfind)



  • gcc or compatible compiler (e.g.: gcc, clang/llvm, suncc)
  • POSIX compatible shell (e.g.: ksh, bash)

First download the latest stable version from github:

mkdir -p ~/src
cd ~/src
curl -L | tar xzv
ln -s ../fluxkit-0.2.5 fluxkit

Thereafter bootstrap the build system:

mkdir -p ~/build/fluxkit_debug
cd ~/build/fluxkit_debug

Finally, build the entire toolkit:

./fluxmake -debug ~/src/fluxkit

Optionally add the build directory to your environment:

export PATH=$PWD:$PATH
echo "export PATH=$PWD:\$PATH" >> ~/.profile
Something went wrong with that request. Please try again.
