Hello,

Using the Ubuntu Development version if gnat is important to you, appears to be a specifically bad idea as they appear to have disabled all the tests at least for Ada.

I am no longer an Ubuntu user myself, as its Development version has become too unstable for me. But I can confirm having seen my collegue struck by your problem too.

Also don't necessarily expect any feedback, the last time it was fixed silently (and left open) too.

Best regards,
Kay Hayen

Concerning my first comment,

here is the solution to be able to us again the gnat compiler tool chain :

sudo ln -s /usr/lib/gcc/i486-linux-gnu/4.3 /usr/lib/gcc/i486-linux-gnu/4.3.1

strace tell us that the gnat command try to open /usr/lib/gcc/i486-linux-gnu/4.3.1/adainclude/system.ads,
and crash as this file does not exist.

A symlink to /usr/lib/gcc/i486-linux-gnu/4.3 solve the problem ....

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497369 about the symlink problem ...

nothing changed from the debian package. please could you file a bug for Debian? afaicr this was disabled because the tests don't work with the changes made to the package.

> with the current gnat it is impossible to compile anything. Neither gnat itself, nor any other file it seems.

is cpp-4.3 installed on the system?

closing. checked with 4.3.2-1ubuntu1 in intrepid

Reopening, this bug still happen on natty.

Trying to execute appears:

$ gnat
fatal error, run-time library not installed correctly
cannot locate file system.ads

raised TYPES.UNRECOVERABLE_ERROR : targparm.adb:177

Searching with strace, show that gnat look for gcc 4.4, but the folder is 4.4.4:
