Thanks, Alan, for all your help with this. For the others on this list, Alan and I communicated offlist a bit over the weekend--the short version is that all of my programming experience has been as a "loner," not involved with other developers on projects, and so the collaboration parts of the infrastructure (CMake, CVS) are all new to me. I'll do what I can to get up to speed. In the meantime, converting more C examples to Ada is pretty easy at this point, so I'll continue with that.
As I understand it, the GNAT (gcc Ada) build system is indeed quite different from the usual C stuff. This is in part because every Ada file explicitly lists all of its dependencies. At build time, only those files that have been changed and their dependencies are recompiled. Some of this magic is handled by the *.ali (Ada Library Information) files which are generated along with the *.o files at compile time. There is a comparison of the GNAT build system with the traditional build system as well as other Ada (library-based) build systems at http://gcc.gnu.org/onlinedocs/gcc-3.3.6/gnat_ug_unx/The- GNAT-Compilation-Model.html#The-GNAT-Compilation-Model. GNAT programs are often made with the convenient gnatmake command, but they can also be made using the usual gcc command; this is discussed at http:// gcc.gnu.org/onlinedocs/gcc-3.3.6/gnat_ug_unx/Compiling-Using- gcc.html#Compiling-Using-gcc. Jerry P.S. I hate to appear so creepily anonymous but I don't like polluting my "Google namespace" with my full name appearing in the several mailing lists that I am on. I am a self-employed Ph.D. Electrical Engineer and inventor with a background in signal processing, audio, and synthetic aperture radar. I live and work in Tempe, Arizona, USA, and my last name is B a u c k. I have a little web site at www.cooperbauck.com. I have switched to Ada after many years of Pascal use. I grew weary of converting between Pascals and decided to see what Ada has to offer, and I have to say that I am mightily impressed. Most people who do what I do use Matlab so I have to endure some overhead (e.g., writing bindings) to pay for my intransigence. On Feb 24, 2007, at 2:00 AM, Alan W.
