Honestly, I don't have the time to make sure every links in my website are still up and alive out there. That's the problem. Even some links from other websites to my Ada projects page became dead after I moved my website to Wordpress with some remake of uri. It is difficult to keep track of what one links to and from. About the compiler, AdaCore has contributed a free gnat compiler to gnu. It is totally free but users have the option to choose to buy a license or support seat from AdaCore for support and getting some "deadly" compiler bugs eliminated. The reason why compilers maker can't make their compiler totally free is very reason behind the complex market. SImply, there is not enough rewards for the compiler makers to open up entirely their compiler to the free market. Company like AdaCore and Aonix are major Ada compiler makers. They have very steep market niche. Their customers are the world's most advanced software developers and heavy industrial company, e.g. Lockheed Martin, Boeing, BAE, and etc. Small and mid sized software development company and one-man shop will not be an interesting profit maker for AdaCore and Aonix and usually do not play very much important role and can be neglected somehow. Take AdaCore for instance, open up the entire compiler market for gnat by giving free compiler has just become a commitment to the software development community and not a profit generating activity. A one-man shop (like me), does not very often need to deal with serious compiler problems and bugs and most often will not encounter one. One-man shop can get some of the design problem solved by posting questions to a usenet like c.l.a. or searching the usenet for already there answers. Recently, Aonix, another major player has opened up by offering free compiler to Linux community. Aonix has been providing free compiler (ObjectAda) to Windows platforms since many years ago. Aonix packages the best IDE and Ada compiler suite into ObjectAda. But again, Aonix is still not opening entire ObjectAda to the free market. Simply because there will be no interest in profit generation. Aonix has a better advantage over AdaCore is that Aonix offers other suites of development tools such as StP, TeleUSE, and etc. People, like me, who has been used to gnat will get lock into gnat because of compiler specific packages like the gnat packages which are not very well supported by ObjectAda. Otherwise, the Ada source can be easily compiled by any Ada compilers. Aonix and AdaCore are just a tip of the iceberg. If you look into Apple's business model, you will find Apple is more successful in open up their development tool to the free market. Apple has been shipping its integrated development tool, xcode, since Mac OS X. And recently, as I read from a mailing list, Apple has integrated gnat 4.0 to its recent xcode release. I still have not get a confirmation from the mailing list. Can anyone confirm the Apple's integration? Developers can develop software using xcode for free. That opens up a very interesting market for Apple. More and more very nice applications, utilities and widgets have become available to Mac users for free or for a fee. In return, Apple is rewarded with more hardware sales. This business model is not applicable and will never become viable to AdaCore, Aonix and as well as anyother Ada compiler makers. Sadly to say that. But on the other hand, you still can use gnat to develop software and sell. How? You can sell services like, installation, maintenance, support, training, upgrades and etc which come with your free application. Or you can sell a hardware which runs a free software developed using gnat compiler. Company like D-Link has been a successful example. D-Link sells their routers which have open source firewall and router software embedded inside their hardware. This way, you will not violate any GPL or GPL related license which gnat is released with. This is the whole new approach of software development industry to generate profit. In fact, we can see the future as software will be free for everyone. You just have to pay for the services that you need. If you don't need that, you just don't have to pay. -- Adrian Hoe http://adrianhoe.net On Sep 17, 2:35 pm, lou wrote: > >The fact that Ada compiler vendors charged outragesous prices > > for > > their compilers helped to discourage commercial organizations from using Ada: > > COBOL, C, C, Pascal, were more affordable. > > Richard Riehle > > This is my very first day on this newsgroup, and I come here after > about a month of frustration trying to learn more about Ada. > As a newcomer, I think I can give an important insight as to what > needs to be done to draw more people into using Ada.
