error installing previous gcc version

error installing previous gcc version

[D'arito]

HI Folks,
I need to "undergrade" my gcc version that comes with openSuse 10.2 . Well
the default version is gcc version 4.1.2 20061115 (prerelease) (SUSE Linux).
I do really need the old version, because my "mentor" told me my code
compiles properly with gcc-3.3.3 ( just I need to compile using a static
library called libESP.a) . So I decided to install a previous version in
order to avoid modify the libESP.a , cause I thought it was harder than
install another compiler version.

After reading in forums, asking buddies, and losing a lot of time( I know
that's the way sometimes) I couldn't install gcc-3.3.3 yet ! It's so
annoying. I just claim for help .

I've achieved to run the configure script in a gcc-build directory, but I
got an error withing the make. :
../../gcc-3.3.3/gcc/read-rtl.c: In function ‘read_rtx’:
../../gcc-3.3.3/gcc/read-rtl.c:653: error: invalid lvalue in increment
make[1]: *** [read-rtl.o] Error 1
make[1]: Leaving directory `/opt/gcc3/gcc-build/gcc'
make: *** [all-gcc] Error 2


I've also tried by using rpms without success too...

Feel free to ask me for important data , kie logs or whatever you need.

I'm able to establish a VNC session if anyone have time to help me online.
thanks a lot , I would appreciate your interest so much !!

I tried to install gcc-3.3.3 with gcc-4.3 and had the same error you
did, and that reinforces my first thought:

My first thought is that gcc-3.3.3 is VERY old (especially for C++)
and you are probably trying to deal with old, non-standard code that
need fixing (including gcc-3.3.3).  I've run into the same kinds of
problems with old C and FORTRAN code and eventually had to bite the
bullet:: fix the old code and bring it into the 21st century.  It
sounds like you're fortunate enough to at least have the original
source code, so you can fix it.

But as a last resort, try to find old 3.3.3 binaries, perhaps even
making a clean installation of Fedora Core 2 (or whichever old FC had
3.3.3 as the default gcc).

LOL.

BTW, I think your "mentor" is not keeping up with the times.

The reason this won't compile is that the 3.3 code used a nonstandard
language extension here (lvalue cast) that was deprecated in 3.4 and
then removed in 4.0.

You run into these general sorts of problems when trying to compile
older code with a newer gcc, because gcc tends to get more strict about
rejecting invalid code over time rather than more permissive.

The solution is that you need to build an intermediate version (most
likely 3.4.x) and then use that to build your desired 3.3.3 version.

If you want a shortcut you can try applying the obstack.h changes from
this patch: <http://gcc.gnu.org/viewcvs?view=rev&revision=72826>.  But
beware that there are almost certainly other incompatibilities lurking
in the gcc code base so using an intermediate version is always the
generally correct solution.

OK.  I can see your problem: you have nonstandard code that gcc won't
compile any more, so you want an old gcc that will compile it.  But the
new gcc won't compile the old gcc either.

I'm guessing that the problem here is that old gcc uses what's known
as an "lvalue cast", which is a language feature that has been removed
from gcc.  It's possible to fix the gcc source so that it doesn't use
an lvalue cast, or it's possible to fix your own code so that it
compiles with a modern gcc.  I'd do the latter.

If you want to fix the lvalue cast in obstack.h you can just do
something like this:

# define obstack_ptr_grow(OBSTACK,datum)			\
__extension__							\
({ struct obstack *__o = (OBSTACK);				\
   if (__o->next_free + sizeof (void *) > __o->chunk_limit)	\
     _obstack_newchunk (__o, sizeof (void *));			\
   void **__tmp = (void**)__o->next_free;			\
   *__tmp++ = ((void *)datum);					\
   __o->next_free = (char*)__tmp;				\
   /* *((void **)__o->next_free)++ = ((void *)datum); */	\
   (void) 0; })

This might be all you need, but I wouldn't guarantee it.  You must
make gcc-3.3.3 with "make bootstrap".
