OpenBSD 3.5 & GNAT

OpenBSD 3.5 & GNAT

[Roman V. Isaev]

Is there any way to install GNAT on new OpenBSD systems 3.4 and 3.5?
They switched to ELF and they don't have GNAT package anymore. I tried
to install old package, enabled a.out, but when I try to run gnatmake
I get an error:

Bad magic: ld.so

Apparently ld.so is an ELF binary too. Any clues? I googled for
answers but did not find anything...

Can you find a complete gcc 3.4 release binary for OpenBSD and use that?

If not, you may need to do a canadian cross from another system..probably
too painful.

Can't find so far. I wonder is it possible to run old GNAT with a.out
emulation, or they made it impossible?

:( Why GNAT disappeared from OpenBSD? It was there in 3.3.

Does the Linux emulator not run in OpenBSD ?. I suppose so.

GNAT Ada can be compiled in Linux running inside of a VMware (Russia uses
the www.damn.to software to make it run longer). An easy thing to do
is to give up on installing GNAT in OpenBSD (unless their Linux emulator
has bugs).

Mr M. Espie has written a lot of messages at the gcc mailing list with
some hints on getting Ada compiled in OpenBSD (I sent quoted messages
privately). The messages seemed rather unhelpful.

Problems with the debugger can be major: in FreeBSD 4, blocking sockets
blocked tasks.

I tried to fix that by compiling up a native FreeBSD GNAT cross-compiler
that generated Linux ELF excutables but the exectuables created were
a bit corrupt:

PS. MinGW now installs out of the box. The GPS debugger was not printing
out the values of variables. It looks like Germans need to keep buying
GNAT Ada Pro. GPS: http://libre.act-europe.fr/gps/


I find my FreeBSD 5 system is auto-erasing. The absence ofthat was a top
reason for minimizing use of Linux.  The popularity of FreeBSD is quickly
rising apparently according to their download stats.

Is what? It deletes itself?

Actually, all no data is lost since again FreeBSD got a corrupted BSD
disklabel. I suppose it could have been this FreeBSD 5.1 problem that
I informed the OpenBSD bugs list about.

However justifiying OpenBSD when trashing FreeBSD was mismatching
with the facts. In fact FreeBSD 5.1 was deleting its own filesystem.

Ugh. I found a way to run GNAT from OpenBSD 3.3 on OpenBSD 3.4. I had
to make /emul/a.out directory and untar base33.tgz and comp33.tgz
there, all details in there in compat_aout. GNAT did compile simple
Ada programs, but when I tried to compile AWS it complained a lot
about pragmas and when I finally got library it refused to link. I get
a bunch of errors about unresolved _inflate and _deflate references,
no matter how much -lz flags I gave...

Anyway, GNAT from OpenBSD 3.3 produces a.out binaries. I downloaded
GCC 3.4 and tried to compile it. When I compile it with default GCC
from OpenBSD 3.4 I get normal C compiler, but no Ada compiler at all.
When I try to compile GCC 3.4 with GCC 3.2.2 from previous OpenBSD
release it DOES find Ada I get a big bunch of errors like this:

....

Any clues? May be I did not install something important? By the way,
is it possible to compile part of GCC 3.4 with system GCC and Ada part
with 3.2.2?
