Question

I installed GNAT on my OS X 10.8.5 machine with the following steps:

Download GNAT GPL from http://libre.adacore.com/download/configurations
Install with ./doinstall, accepting all the default options
Added /usr/local/gnat/bin to $PATH

After trying to compile a simple hello world example I get this error:

$ gnat make hello
gcc -c hello.adb
gnatbind -x hello.ali
gnatbind: Cannot find: s-stalib.ali
gnatmake: *** bind failed.

Any idea why this might happen?

PS: gnat make -a hello works, but creates tons of files and should not be required as far as i know.

Edit: As requested, here is the output of gnatls -v

Interestingly, the requested file s-stalib.ali is not contained in this directory.

Solution

If you say gnatls -v (or gnat list -v), it lists (amongst other things) the object search path: here,

...
Object Search Path:
   <Current_Directory>
   /opt/gnat-gpl-2013/lib/gcc/x86_64-apple-darwin12.2.0/4.7.4/adalib/
...

What does yours say? is it right? if the files are there, are they readable?

[Later]

OK, you have 9 s-s*.ali files, with protection -rw-rwxr--@ (I'm not sure what the @ means!), whereas I have 19, with protection -r--r--r--@. This looks as though the installation didn't complete for some reason.

When I install GNAT, I use sudo: sudo ./doinstall. Could that be the difference?

The README says that doinstall leaves install.log in the current (distribution, I suppose) directory; that might give some clues.

If you do decide to rebuild the library, it's be best to use Makefile.adalib in the "installed" adalib/ directory.

Good luck!
