But compiling Ada with MinGW or GCC is different, isnt' it ? As I've quoted, the copyright notice from GNAT GPS and Ada in standard packages from MinGW, are not the same (by the way, I do not really know how much code produced by MinGW and GNAT GPS are different, but I suppose it is at least a bit trustable). > That is, the source code must be available for those who use your program= . =A0 > You can sell the binaries for $xx.xx, and you may either give the source = if > they ask or in some cases you can charge addition $yy.yy for the source. Well, my concern with the GPL license is not so much source code accessibility, but rather the right for redistribution. This is not compatible with low price distribution. Using an open source GPL license (which is a kind of open source license, but not the sole one possible), should require a hight price for a single sell. Otherwise, it would not work with a low price sell, beceause as soon as the first sell would be done, it could be distributed free of charge, and no body will buy it (even if for a low price). > GNAT Pro (around $15K a year) will allow a commercial program with any > license you desire, GPL or non-GPL. I know the princing, I've already been contacted by AdaCore, about more than one year ago after an e-mail contact. At the time, I thought there were perhaps low cost license without support, but I was tolded it is not possible (from Ada Core France). The pricing was mostly the same (12K=80 a year at this time). Too much for somebody. But can be understanded, as GNAT is very a good and trustable compiler. I guess big coporation requiring hight trustability will think this is a good price (and it is probably for that, sure).
