Hi,

Just because a compiler is not free does not mean it is not relevant to som=
eone. In addition, the OP did _not_ specifically ask for an open source com=
piler. They asked if there are other compilers. Hobbyists generally want a =
free compiler, so by default GNAT is the one that is used. For companies wh=
o want commercial support and are fine with paying money, then the other op=
tions are perfectly fine.

Of the commercial ones listed, Janus/Ada is the more affordable one for an =
individual willing to spend money (see http://www.rrsoftware.com/html/compa=
nyinf/prices.htm), especially if they are a student (http://www.rrsoftware.=
com/html/companyinf/educ.htm). While it's not as up to date as GNAT in term=
s of Ada2012 support, it's still enough to develop software with (note: Win=
dows only which is fine for many people and can probably run on Wine for Li=
nux users). Judging by the Randy's posts in this group, one can expect good=
 support from RRSoftware.

I should point out that PTC is known to provide free access to their compil=
ers if it is for developing *open source* Ada software. Gautier has confirm=
ed this on Reddit (https://www.reddit.com/r/ada/comments/hw33kr/ptc_objecta=
da_for_windows_version_102_outprovides/fyzgpss?utm_source=3Dshare&utm_mediu=
m=3Dweb2x). So there is potential
