gnat : "ada.calendar.formatting" is not a predefined library

[Sébastien]

Hi,

When I try to compile aws, I get the following message:

mscm@routeur:~/gnat/aws/AWS-gpl-2.3.0$ make build
Building libz.a (Zlib library)
gnatmake: objects up to date.
gnatmake: objects up to date.

compilation error
make[1]: *** [build] Error 4
make: *** [src_build] Error 2

I try the following sample test:

with Ada.Calendar.Formatting;

procedure test is
begin
         Ada.Text_IO.Put_Line("test");
end test;

And get at compile time:
mscm@routeur:~/gnat/aws$ gcc -gnat05 -c test.adb
test.adb:1:06: "ada.calendar.formatting" is not a predefined library unit

I'm under ubuntu, and it looks like something is missing in gnat, how to 
fix it?

I'm using :
mscm@routeur:~/gnat/aws$ gnat
GNAT 4.2.1 (Ubuntu 4.2.1-5ubuntu6)

GNAT 4.2.1 does not fully support all Ada 2005 features.

Try FSF GNAT 4.3 or GNAT GPL 2007. They have better support.
Alternatively, use AWS 2.2.0. It should compile with GNAT 4.2.1.

<plug>
Alternatively, switch to Debian which has gnat-4.3 in testing, and
participate in upgrading the existing libaws 2.2 package to 2.3 :)

I'm under ubuntu and that's a professional machine, so I can't (and really I would).

At home, I'm using FreeBSD, I'll give a try tonight.

If you're going to be "professional", you should use the packages that
come with the "professional" distro. So, your best option is to fall
back on libaws-dev 2.2 and gnat-4.1 which come as part of Ubuntu. The
version after today's 8.04 will probably have gnat-4.3 and libaws 2.3.

You are completly right, I didn't even check if there was some compiled 
version. I'm going to open an other thread about missing standard lib 
stuff anyway :-)

Thanks for you help.

8.04 LTS has gnat-4.2.3 and libaws 2.2.

Which are ABI incompatible with each other.

Looking more closely, libaws2.2 depends on libgnat-4.1.
This is resolved by Debian's package system. (libaws2.2
claims to depend on libldap2, too, which is not available
with Ubuntu 8.04 LTS at this time.)

The unnumbered package "gnat" will install GNAT 4.2.3.

Talk about a "professional" distribution :)

I don't know what Ubuntu changed to gcc-defaults but, in Debian, in
gcc-defaults version 1.64 I made gnat-4.3 the default on all
architectures; version 1.66 reverted to gnat-4.2 on alpha, mips and
mipsel without consulting with me, and 1.70 finally reverted that,
thereby completing the transition to gnat-4.3 as the default on all
architectures.

I never intended gnat-4.2 to be the default on any architecture and
Ubuntu diverges from Debian and risks breaking package dependencies.
So, at this point, I am forced to recommend against Ubuntu 8.04 for
Ada development.  Previous versions are OK since they follow the
policy for all Ada packages.  If you want a stable Ada development
platform, get Debian stable, which has "long term support" built in.

I'm quite agree with you, I successfully installed aws on freebsd recompiling 
it, but I had to correct some stuff in the aws-2.3.0 and xmlada code . In any 
case, I just was able to compile it with gcc43, because some standard ada 
library were missing in gcc41 and gcc42.

Now, I just have to try it :-)
