C++ Seat Availability Calculator Library

Summary

AvlCal aims at providing a clean API and a simple implementation (C++ library) of an Airline-related Seat Inventory Availability Calculation system. That library uses the Standard Airline IT C++ object model (https://github.com/airsim/stdair).

AvlCal makes an extensive use of existing open-source libraries for increased functionality, speed and accuracy. In particular the Boost (C++ Standard Extensions: https://www.boost.org) library is used.

AvlCal is the one of the components of the Travel Market Simulator (https://travel-sim.org). However, it may be used in a stand-alone mode.

Installation

On Fedora/CentOS/RedHat distribution

Just use DNF (or Yum on older distributions):

$ dnf -y install avlcal-devel avlcal-doc

You can also get the RPM packages (which may work on Linux distributions like Novel Suse and Mandriva) from the Fedora repository (e.g., for Fedora Rawhide, https://fr2.rpmfind.net/linux/RPM/fedora/devel/rawhide/x86_64/)

Building the library and test binary from Git repository

The Sourceforge Git repository may be cloned as following:

$ git clone git@github.com:airsim/avlcal.git avlcalgit # through SSH
$ git clone https://github.com/airsim/avlcal.git # if the firewall filters SSH
$ cd avlcalgit

Then, you need the following packages (Fedora/RedHat/CentOS names here, but names may vary according to distributions):

  • cmake
  • gcc-c++
  • stdair-devel, airrac-devel, rmol-devel, airinv-devel
  • boost-devel
  • zeromq-devel
  • readline-devel, ncurses-devel
  • soci-mysql-devel
  • python-devel
  • gettext-devel (optional)
  • doxygen, ghostscript, graphviz and tetex-latex (optional)
  • rpm-build (optional)

Building the library and test binary from the tarball

The latest stable source tarball (avlcal*.tar.gz or .bz2) can be found on GitHub: https://github.com/airsim/avlcal/releases

To customise the following to your environment, you can alter the path to the installation directory:

export INSTALL_BASEDIR="${HOME}/dev/deliveries"
export AVLCAL_VER="1.00.6"
export LIBSUFFIX_4_CMAKE="-DLIB_SUFFIX=64"

Then, as usual:

  • To configure the project, type something like:
  mkdir build && cd build
  cmake -DCMAKE_INSTALL_PREFIX=${INSTALL_BASEDIR}/avlcal-${AVLCAL_VER} \
   -DWITH_STDAIR_PREFIX=${INSTALL_BASEDIR}/stdair-stable \
   -DWITH_AIRRAC_PREFIX=${INSTALL_BASEDIR}/airrac-stable \
   -DWITH_RMOL_PREFIX=${INSTALL_BASEDIR}/rmol-stable \
   -DWITH_AIRINV_PREFIX=${INSTALL_BASEDIR}/airinv-stable \
   -DCMAKE_BUILD_TYPE:STRING=Debug -DENABLE_TEST:BOOL=ON -DINSTALL_DOC:BOOL=ON \
   -DRUN_GCOV:BOOL=OFF ${LIBSUFFIX_4_CMAKE} ..
  • To build the project, type:
  make
  • To test the project, type:
  make check
  • To install the library (libavlcal*.so*) and the binary (avlcal), just type:
  make install
  • To browse the (just installed, if enabled) HTML documentation:
  open file://${INSTALL_BASEDIR}/avlcal-stable/share/doc/avlcal-${AVLCAL_VER}/html/index.html
  • To browse the (just installed, if enabled) PDF documentation:
  evince ${INSTALL_BASEDIR}/avlcal-stable/share/doc/avlcal-${AVLCAL_VER}/html/refman.pdf
  • To package the source files, type:
  make dist
  • To package the binary and the (HTML and PDF) documentation:
  make package
