 |
|
Hi,
I have been using LEDA for an year with old version of gcc (2.95). Now when
I upgraded my gcc to version 3.3.1, I get stange errors like the following:
~/LEDA/incl/LEDA/std/strstream.h:9:23: strstream.h: No such file or
directory
In file included from ~/LEDA/incl/LEDA/event.h:136,
from ~/LEDA/incl/LEDA/graph.h:39,
from ~/LEDA/incl/LEDA/graphwin.h:28,
from mappingall.c:3:
~/LEDA/incl/LEDA/event_macros.h:194:30: pasting "," and "_E1FMT0" do
es not give a valid preprocessing token
~/LEDA/incl/LEDA/event_macros.h:194:30: pasting "," and "_E1FMT0" do
es not give a valid preprocessing token
mappingall.c:2423: error: ISO C++ forbids assignment of arrays
mappingall.c:2428: error: ISO C++ forbids assignment of arrays
What should I do to run the program (I have lots of array assignements
and I don't want to change the code now). Is there any flags that I
can set to run the program.
Thanking in Advance

This can be fixed. In gcc 3.2.2 there was a file strstream.h in
/usr/include/c++/3.2.2/backward. In 3.3.x this file is missing. You can
copy it from an older version or put the following into a file
strstream.h in the backward-directory:
#ifndef _CPP_BACKWARD_STRSTREAM_H
#define _CPP_BACKWARD_STRSTREAM_H 1
#include "strstream"
using std::strstreambuf;
using std::istrstream;
using std::ostrstream;
using std::strstream;
#endif

Are you using the option --pedantic? This may cause the problem.

Which doesn't do the same thing, and would require extensive
modifications to the existing library.

Sounds like they are doing a maximum, then, to make the compiler useless
for real world users.

No, indeed; it does standard C++ type things.

Nope; it's perfectly usable for C++ coders.

The older versions still exist; they haven't been taken off the
market. Cygnus still maintains gcc 2.9 (no, not 2.95) for a
customer that does not want to break binary compatibility by
switching to a later version.

No, they are trying to make it MORE useful by making the default behavior |
consistant with the standard rahter than junking it up with all the garbage
that some GCC developer in the past thought was a neato idea at the time.

It looks like your code is trying do something like
#define PASTE(A, B) A ## B
// ....
PASTE(, _E1FMTO)
which is an invalid CPP operation.

The backward compatibility string stream header, as described in
appendice D, is spelled <strstream> (with no extension).

#define _CPP_BACKWARD_STRSTREAM_H 1
#include "strstream"

Be careful: There is a standard header <strstream> (as described by
the standard) comming with 3.3.x

In fact, it was renamed to
