DOWNLOAD
Gildas and its dependencies can be installed with MacPorts.
Gildas is available in the MacPorts distribution. Unless you are an advanced user (see below: Installation from sources), this is the recommended way to install Gildas under Mac OSX. Gildas installation with MacPorts is straightforward. Follow the installation steps as explained in this guide.
The MacPorts Gildas package is maintained on a regular basis. Usually the package is updated a few days after a source release, so that the latest enhancements or bug fixes in Gildas are quickly available to Mac users.
As an alternate solution, it is possible to install first Gildas dependencies using MacPorts. You will find the MacPorts dmg image here.
Note that MacPorts requires Xcode which you can get with an Apple identifier (more than 1 GB to be downloaded from the app store). Xquartz is also needed for Gildas plots.
Installing the dependencies is explained in this guide.
Linux version of GILDAS are distributed only as sources because binaries are not portable (due to the many different possible combinations of processors, operating system and compilers). We thus tried to ease building as much as possible: If GILDAS dependencies are correctly installed, building the binaries should just need the following sequence of commands
shell-prompt> unxz gildas-src-mmmyya.tar.xz shell-prompt> tar -xvf gildas-src-mmmyya.tar
or even simpler, let tar uncompress the archive by itself (automatic detection from the file extension):
shell-prompt> tar -xvf gildas-src-mmmyya.tar.xz shell-prompt> cd gildas-src-mmmyya shell-prompt> source admin/gildas-env.sh shell-prompt> make shell-prompt> make install
Exactly the same sequence of command should be used for Mac OSX in case the binary distribution does not match your needs.
Visit the download area and get the last monthly release named:
gildas-src-mmmyya.tar.gz
where mmm are the 3 first letters of the current month, yy are the last two digits of the current year and a a letter defining the minor version of the monthly release: a for the initial monthly release, b for the monthly release with the first bug fix, c for the monthly release with the second bug fix, and so on.
Daily releases are there just as a convenience for beta testers. We strongly discourage standard user to get them.
In contrast with executables, compiled PDF and HTML documentations are inherently portable. We thus also distribute them (though separately from sources).
Visit the download area and get the last monthly release named:
gildas-doc-mmmyya.tar.gz
where mmmyya has the same meaning as above.
