Gdl
From RHESSI Wiki
GDL is a free open-source version of IDL. Currently, GDL does not support GUI widgets therefore things like the hessi GUI will not work in GDL.
Installing
Mac OS X
The source code for GDL can be obtained from the GDL homepage. This source code needs to be compiled in order to create a gdl executable. Unfortunately, GDL uses many libraries which are not available with a standard installation of Mac OS X. Some programs such as Macports can make this process easier and will automatically obtain all of the libraries necessary to compile GDL.
- Install Apple's XCode. This will install many important libraries as well as install a compiler, gcc.
- Install macports.
- Run the following command which will (by default) install gdl in /opt/local/bin/
sudo port install gnudatalanguage
- You should now be able to run gdl by typing "gdl" in the Terminal.
- Create a symbolic link to gdl with the following command.
ln -s /opt/local/bin/gdl /opt/local/bin/idl
- You should now...
