Building GNAT with GCC 3.4.3

Building GNAT with GCC 3.4.3

[braver]

So I tried to build a new GNAT from GCC 3.4.3, the latest release, in
order to check how it handles hot areas such as 'Size.  Strangely, I'm
not getting gnatlib_and_tools target in the Makefile in the build
directory /gcc/ at all!  No matter what I give to configure --
--enable-languages=ada,... --enable-libada, and doing make bootstrap,
saying ADAC=gnatgcc before configure -- still doesn't show the target
in the Makefile.  I have GNAT 3.13p, it's a SuSE Linux, and I wonder
what can be missing where.

Cheers,
Alexy

Try the gcc/gcc directory. By the way, this target has been removed in
gcc from CVS.

Ciao,

Duncan.

Could you be more precise as to what target you're talking about?

The gnatlib_and_tools target.

Alas, there's no target with the word gnat or ada in any of the
Makefile's in the resulting build directory!  Trying to compile an Ada
file after make install says that Ada compiler is not installed on this
system.  I got the full GCC 3.4.3 release, then unpacked Ada over it
just it case -- seems the same gcc/ada source subdirectory.  Hmm...

BLFS book (http://www.linuxfromscratch.org/blfs) recommends for gcc-3.4.1
the following commands to build GNAT:

make -C gcc gnatlib-shared
make -C gcc gnattools

Anyway gnat 3.13p might be a problem, try 3.1[45]p instead. For me
3.15p failed with gcc 3.3.

Also make sure that gcc finds you gnat installation (I don't know how).
Perhaps using the gnat gcc to build the whole new compiler could solve
the problem.

Chances are that configure scripts (at top level, or started by make)
will call the system's compiler driver to compile a short Ada program.
This could mean gcc. I believe that the ADAC variable is no longer in
use, but you can set CC. Or you could add a prefix to the system's
path variable pointing to a directory with a gcc in it that understands
both C and Ada.

HTH,

I ended up getting the CVS sources for GCC 4.1.0 and compiling it with
the old GNAT 3.13p by prepending CC=gnatgcc -- works like a charm, no
other configs than the configure options.  And now I get f95 too!
(Needed to get "GMP with MPRF" for that.)  More Fortran and Ada,  Ada
95 and Fortran 95!
