Building dejagnu with latest GCC

Building dejagnu with latest GCC

[Richard Kenner]

I'm trying to recreate my tool environment, but I get the follow.
I don't know C++, so don't know if this represents a GCC or Dejagnu
problem.  Any help would be appreciated.

(I'm still looking for a pointer to the versions of tools that GCC
maintainers should be using, by the way.)

This seems to be a dejagnu problem.  It would be better if it used
antiquitated and deprecated headers.  In this case, <sstream> is a
better alternative.  Or you want to issue -Wno-deprecated as suggested
in the message.

I don't have a copy of dejagnu.h;  this looks odd.

Could you show us a bit of that line?  Which version of g++ +
libstdc++-v3 are you using?

rm -rf the subdirectory (the one with unit.cc), or use the previous 
version of Dejagnu (1.4), or complain to rob (the dejagnu people) , or 
...
Sometimes life is just too short.

I just built it on hppa-linux 3.3 20020802 (experimental).  The testsuite
results seem about the same as with building with 3.0.4.  You don't need
g++ for the build.  I can't comment on the libstdc++-v2 requirement.
1.4.0 is currently the version supplied with debian linux and it's the
one that I have had the best success with.

I agree, the output *is* confusing.  It would be nicer if gcc would
prefix error messages with "error:" (like it prefixes warning messages
with "warning:").  This would make it easier to spot errors in cases such
as this one where an error is mixed with a bunch of warnings.

Yeah, you're right.  

I'll try to grab dejagnu-cvs and whether the problem is still there
and if so send a patch.

Re: Building dejagnu with latest GCC

[Richard Kenner]

    Kenner, please could try to replace

        sb->setbuf(bbuuff, 5120);

    with

        sb->pubsetbuf(bbuuff, 5120);

    and report what happens?

That does it.  Thanks.

Changing setbuf to pusetbuf solves this one.

But, I can't solve this one in one line.

Here are the definitions that are flagged:

   // somewhere in dejagnu.h
  char *outstate[] = {
      "FAILED: ",
      "PASSED: ",
      "UNTESTED: ",

   int
   main (int argc, char *argv[]) {

   //    char **os2 = outstate;

Array assignment aren't even valid in C.

Hi,

  -fpermissive doesn't help for the accessibility problem 

  /usr/local/include/c++/3.2/streambuf:416: `std::basic_streambuf<_CharT,

The piece of code incrimintated is:

    streambuf *sb =  cout.rdbuf();
    char bbuuff[5120];
    sb->setbuf(bbuuff, 5120);

streambuf::setbuf() is protected and is there only for derived
classes. For public use, the right function is streambuf::pubsetbuf().
Kenner, please could try to replace

    sb->setbuf(bbuuff, 5120);

with

and report what happens?

I can't figure out how to add it except by modifying the Makefile, but when
I do, it *appears* to help, since it looks like it's changing errors
into warnings, but the command still fails.  I'm not sure why, though, since
the error message output is confusing:

I thought the thread was about how new a version of gcc could be used.  1.4 
appears to require libstdc++-v2, so we're requiring an older gcc to build the 
test framework for the current gcc.

Personally, I like 1.4.  I've had problems with 1.4.[12] and cvs
versions running tests more than once, and being more restrictive
in command line arguments.  This causes problems running some
testsuites.  There was some previous discussion of this on the
list a few months ago.

Oh well, forget about what I said: I got the source and had a look at
the file dejagnu.h.  It is really dejagnu problem:  It includes
standard headers but failed to notice that the standard library is in the
standard namespace.  Please put this 

   using namespace std;

    This seems to be a dejagnu problem.  

Is there a version that can be compiled with the current GCC?

    Which version of g++ + libstdc++-v3 are you using?

The 3.2 branch as of around noon today.
