How to find a native GNAT compiler?

How to find a native GNAT compiler?

[thymallus1]

I used GPS from GPL-2010, with win32ada, without problem. Now I
installed GPS-2011, and I tried to install win32ada for GPL-2011
(win32ada-gpl-2011.exe downloaded from Adacore). It appears that this
installation is only possible if "a native GNAT compiler" is found on
the system. After some searches with google I found it is possible but
very difficult to build a native Ada compiler from the Gnat sources.
Do I have to wait for a win32ada compatible with GPL-2011 from
Adacore?

You probably need to give more details. The native Ada compiler is GNAT 
GPL 2011. So you should have it. Is it really on your PATH?

You are right. I previously installed GPS 2010 in D:\GPS-2010; and I
installed the downloaded GPS-2011 in D:\GPS-2011. There were remnants
of 2010 forgotten in the path. I cleaned this mess and I put in the
path the directory containing gnat1.exe. Then I run again the win32ada
installer. However, I got the same message ("Setup couldn't find a
native Ada compiler on your system"). I decided to bypass this
warning, and "Performing automatic installation using compiler in D:
\GPS-2011" was displayed until it ends up by "installation completed".
Thank you for your help.
Phil.

So you are OK now?

For future reference -- the directory that should be in your path is the
one containing gcc.exe, gnatmake.exe. gcc.exe knows how to find the
compiler internals such as gnat1.exe it needs relative to itself.
