MaRC

MaRC

MaRC - Map Reprojections and Conversions - is a program and library designed to produce map projections from digital images or from computed values of incidence, emission or phase angles, and latitudes and longitudes. Multi-plane maps can be created with digital image data in several planes and incidence, emission, phase angles, latitudes and longitudes in other planes. Placement of data in a given plane is completely arbitrary. The user decides in what plane to place a given set of data. Created maps are stored in FITS (Flexible Image Transport System) format.

Getting Started

MaRC may either be built from a source tar archive or from a clone of its source repository on GitHub. If you’re an end-user that just wants to run MaRC, building from the self-contained source tar archive will get you up and running sooner.

Building From the Source tar Archive

The quickest way to get started with MaRC is to download the self-contained source tar archive (e.g. marc-0.9.11.tar.gz) from the releases page. Other than required third party programs and libraries it contains everything needed to build and install MaRC. Once the prerequisites are installed, simply build MaRC as follows:

tar xf marc-0.9.11.tar.gz
cd marc-0.9.11
./configure
make

The MaRC binary will reside in the “src” subdirectory. Documentation will be in the “doc” subdirectory if your system has the necessary text utilities to build them.

Additional build details and instructions may be found in the INSTALL file shipped with the self-contained source tar archive, as well as by passing the --help command line option to the configure script.

Building From Git

If you plan on contributing to MaRC or want the latest unreleased code, it is best to clone MaRC from its GitHub repository. However, you will need to satisfy additional build prerequisites. See the Prerequisites section below for additional details. Once all prerequisites have been satisfied, clone and build MaRC as follows:

git clone git@github.com:ossama-othman/MaRC.git
cd MaRC
./bootstrap
./configure
make

Prerequisites

MaRC is currently only supported on Unix-like platforms, and has the following build dependencies:

• C++ compiler
  • The C++ compiler should support the C++14 standard or better. MaRC is known to build with g++ and clang++, but it should work with other C++14 conforming compilers.
• CFITSIO library
  • Often available as prepackaged binaries on various platforms. Additional details are available on the CFITSIO homepage.
• pkg-config

Maintenance and Git Based Build Dependencies

Additional dependencies exist when building MaRC from Git, when performing maintainer-like modifications to the MaRC package as a whole, or generating a new source distribution:

• GNU Autotools
  • Autoconf
  • Autoconf Archive
  • Automake
  • Libtool
• Text Parser and Scanner Generators
  • GNU Bison
  • Flex
• Documentation Generators and Converters
  • Doxygen
  • GNU Texinfo
  • Pandoc

Platform-specific Dependencies

• macOS
  • The easiest way to get MaRC up and running on macOS is to install the required software listed above through the Homebrew package manager.

Installing

MaRC’s build infrastructure supports the usual GNU Autotool provided build and install targets, including the install target. To install MaRC, run make as follows:

make install

For example, on Linux platforms where the default installation prefix is /usr/local MaRC file installation locations could be the following:

File	Location
marc	/usr/local/bin
libmarc	/usr/local/lib
MaRC headers	/usr/local/include/marc
documentation	/usr/local/share/marc
man pages	/usr/local/share/man/

Further details are available in the INSTALL file.

Running the tests

MaRC’s test suite may be run from the top-level source directory after the configure script has been run like so:

make check

Code coverage results may also be generated by building MaRC and running tests like so:

./configure --enable-code-coverage
make check-code-coverage

This requires gcov and lcov to be installed. HTML formatted code coverage results will be stored in a folder in the top-level source directory, e.g. MaRC-0.9.11-coverage. Note that enabling code coverage instrumentation disables optimization.
