Supported systems (12-nov-24)

GILDAS compiles successfully and is (at least minimally) tested on the following systems:

The reference system at IRAM is a Debian 12 running on a 64 bits PC (x86_64 processor), using the Intel Fortran compiler (ifort) version 2021. Please refer to the Download section to get the necessary information to build Gildas.

Successful building of GILDAS binaries on a UNIX/Linux/OSX system minimally requires:

• Bourne compatible shell (sh, ksh, bash, etc...) for build purpose only; the end-users can then use the GILDAS programs from csh–like or Bourne-like shells;

• GNU make for build purpose;

• NROFF for on-line help building;

• a C compiler (either GCC or the native C compiler);

• a Fortran-90/95/2003/2008 compiler:

  • the GNU Fortran compiler (gfortran 9.0 or above) is supported.

  • Intel distributes a Fortran compiler (ifort). Academic researchers can apply to discounted licenses. Versions greater than 11.1 are supported.

  • g95 is now too old to compile Gildas, and chances to see a new release are getting smaller and smaller.

• GTK+ binaries and development package. It is usually found on the Linux distributions repositories under the name gtk+-2.0 and gtk+-2.0-devel. These packages are expected to be found thanks to the pkg-config tool.

• cfitsio if you need MRTCAL.

• Python >= 2.6 and its array module Numpy if you plan to use the Gildas-Python binding, including the Weeds package in CLASS. Python 3 is supported; Gildas will use the Python version as found from the "python" executable in the environment.

Successful building of PDF/HTML documentation minimally requires recent versions of:

• ps2epsi;

• epstopdf;

• latex (version 2e with makeidx, graphicx and html package).

• latex2html;

• pdflatex;

For your convenience, we distribute compiled PDF/HTML documentation in case you do not have those tools.
