Packaging GMT

These recommendations are directed at package maintainers of GMT.

First split off DCW-GMT and GSHHG into separate architecture independent packages, e.g., dcw-gmt and gshhg-gmt, because they have a different development cycle. Files should go into directories /usr/share/dcw-gmt/ and /usr/share/gshhg-gmt/ or /usr/share/gmt/{dcw,gshhg}/. Then configure GMT as shown below.

DCW-GMT

• Homepage: https://www.soest.hawaii.edu/pwessel/dcw/
• Summary: Digital Chart of the World (DCW) for GMT
• License: LGPL-3+
• Source:
  • https://www.soest.hawaii.edu/pwessel/dcw/dcw-gmt-x.x.x.tar.gz
  • ftp://ftp.soest.hawaii.edu/dcw/dcw-gmt-x.x.x.tar.gz
• Description: DCW-GMT is an enhancement to the original 1:1,000,000 scale vector basemap of the world, available from the Princeton University Digital Map and Geospatial Information Center. It contains more state boundaries (the largest 8 countries are now represented) than the original data source. Information about DCW can be found on Wikipedia (https://en.wikipedia.org/wiki/Digital_Chart_of_the_World). This data is for use by GMT, the Generic Mapping Tools.

GSHHG

• Homepage: https://www.soest.hawaii.edu/pwessel/gshhg/
• Summary: Global Self-consistent Hierarchical High-resolution Geography (GSHHG)
• License: LGPL-3+
• Source:
  • https://www.soest.hawaii.edu/pwessel/gshhg/gshhg-gmt-x.x.x.tar.gz
  • ftp://ftp.soest.hawaii.edu/gshhg/gshhg-gmt-x.x.x.tar.gz
• Description: GSHHG is a high-resolution shoreline data set amalgamated from two databases: Global Self-consistent Hierarchical High-resolution Shorelines (GSHHS) and CIA World Data Bank II (WDBII). GSHHG contains vector descriptions at five different resolutions of land outlines, lakes, rivers, and political boundaries. This data is for use by GMT, the Generic Mapping Tools.

GMT

• Homepage: https://www.generic-mapping-tools.org/
• Summary: Generic Mapping Tools
• License: GPL-3+, LGPL-3+, or Restrictive depending on LICENSE_RESTRICTED setting
• Source:
  • ftp://ftp.soest.hawaii.edu/gmt/gmt-6.x.x-src.tar.xz
  • ftp://ftp.soest.hawaii.edu/gmt/gmt-6.x.x-src.tar.gz
• Description: GMT is an open-source collection of command-line tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing high-quality illustrations ranging from simple x–y plots via contour maps to artificially illuminated surfaces and 3D perspective views. It supports many map projections and transformations and includes supporting data such as coastlines, rivers, and political boundaries and optionally country polygons.
• Build dependencies:
  • cmake
  • gcc
  • curl
  • netcdf
  • gdal
  • pcre
  • fftw
  • glib2
  • lapack
  • openblas
  • dcw-gmt
  • gshhg-gmt
• Runtime dependencies:
  • ghostscript (required)
  • curl (required)
  • netcdf (required)
  • gdal
  • pcre
  • fftw
  • glib2
  • lapack
  • openblas
  • dcw-gmt
  • gshhg-gmt (at least the crude resolution GSHHG files are mandatory)
• CMake arguments:

  -DCMAKE_C_FLAGS=-fstrict-aliasing
  -DCMAKE_INSTALL_PREFIX=${prefix}
  -DDCW_ROOT=${prefix}/share/gmt/dcw
  -DGSHHG_ROOT=${prefix}/share/gmt/gshhg
  -DNETCDF_ROOT=${prefix}
  -DFFTW3_ROOT=${prefix}
  -DGDAL_ROOT=${prefix}
  -DPCRE_ROOT=${prefix}
  -DGMT_INSTALL_TRADITIONAL_FOLDERNAMES=off
  -DLICENSE_RESTRICTED=LGPL or -DLICENSE_RESTRICTED=no to include non-free code
  

Note that you have to configure and build out-of-source. It is safe to make a parallel build with make -j. It is expected that the GMT supplements plugin be distributed with the core programs.
