cannot build gcc 3.2.3 in Suse 10.3 (gcc 4.2.1)

cannot build gcc 3.2.3 in Suse 10.3 (gcc 4.2.1)

[Matteo Rama]

hello,
I've installed Suse 10.3, which has gcc version 4.2.1 .
I need also an older version of gcc, for example 3.2.3 but I haven't managed
to install it.

I downloaded gcc-3.2.3.tar.gz (the md5sum check was ok) then:

>tar -zxf gcc-3.2.3.tar.gz
(the dir. gcc-3.2.3 is created)
>mkdir obj
>cd obj
> ../gcc-3.2.3/configure --prefix=/usr/local/gcc/3.2.3
Here is the output:
http://docs.google.com/Doc?id=dgwhbj6q_56mg3db2fd
>make
here the compilation fails. The output I get is here:
http://docs.google.com/Doc?id=dgwhbj6q_57f39sdqcp

Any help in understanding how to fix the problem would be very much appreciated.
Best regards,
  Matteo

I think it's complaining about an lvalue cast.

It might be as simple as changing that line to

	      obstack_ptr_grow (&vector_stack, read_rtx (infile));

thanks for the reply. It looks like replacing line 662 of read-rtl.c with
obstack_ptr_grow (&vector_stack, read_rtx (infile));
doesn't fix the problem. The error is still there:
...
../../gcc-3.2.3/gcc/read-rtl.c: In function 'read_rtx':
../../gcc-3.2.3/gcc/read-rtl.c:662: error: lvalue required as increment operand

not allowed in ISO C90
../../gcc-3.2.3/gcc/read-rtl.c:662:60: warning: (this will be reported
only once per input file)
make[1]: *** [read-rtl.o] Error 1

make: *** [all-gcc] Error 2

regards,
  Matteo

Well, you're going to have to fix the code.  Feel free to ask us, but
we'll need more information, such as the preprocessed source.

Yeah, I suppose I could try building it myself, but it's not a very
interesting thing to do.  I might try a build later.

Andrew.

I thought the usual suggestion, if you don't want to fix the source
code, was to build one of the earliest gcc versions which has this bug
fixed.  Then you should be able to use this older version to build the
buggy version.

OK, I tried it.

Configure like this:

  CC='gcc -g -ansi -std=c89' /home/aph/gcc/gcc-3_2-branch/configure --enable-languages=c++

Build:

  make bootstrap

Ought to do it.

Andrew.
