rIDL has been extremely useful for me when using IDL from the command line, but so far I only had it building on Mac OS X. I finally broke down and made a real build system for rIDL based on CMake. I have currently tested builds on Mac OS X and 64-bit Linux, though I am hoping it works more widely.
Get the lastest source code with Subversion:
$ svn co http://svn.idldev.com/ridl/trunk ridl
I currently don’t have any official releases of rIDL, it is definitely a work in progress. See the README file in the source for instructions on building.
$ sudo brew install readline
Readline is usually available on most Linux systems.
Let me know if there are issues!
