Configure/compile failure on Solaris 10 Sparc Ultra 25

Configure/compile failure on Solaris 10 Sparc Ultra 25

[Glasser, Nathan]

Hello,

I tried to build Emacs-21.4a (emacs-version says 21.4.1) on Solaris 10
running
on a brand new Sparc Ultra 25 system, and encountered a difficulty. I
also
tried several older Emacs versions, and ran into the same difficulty.

The compiler is "Sun WorkShop 6 update 2 C 5.3 2001/05/15".
Admittedly, this is a very old version of their compiler, but because
that is the version I must use for other reasons, it's what I've
been using to attempt to compile Emacs. I've used this compiler version
to compile Emacs a number of times before in the past on other Sparc
Solaris
systems without a problem (possibly not Solaris 10, though).

When I run configure, configure runs cpp to test for various header
files
being present, and other things. However, these often got errors,
because the
symbol "__sparc", which would normally be defined if cc was run, was not
defined, and lots of system header files depended on it. Consequently,
configure got wrong ideas about the presence of features, and the
compile
failed.

My kludge to get around this was to change line 481 of configure as
shown
here:

echo '#define __sparc 1' > confdefs.h

A better fix might be to use "cc -E" rather than cpp; I tried this and
the
symbol is defined using the former, but not the latter.  I can't tell
you why
this used to work in the past, but in my current setup it does not.

Thanks,
Nathan

I'm a bit confused. Are you saying it does _not_ work if you use "cc
-E" as the preprocessor? Does it work if you use "cc -E -Xs", making
sure the "cc" is the same one as your compiler?

We hope to release Emacs 22 soon, and it would be helpful if you
could see if that works for you. The latest pretest version at present
is 22.0.97, which you can get from alpha.gnu.org/gnu/emacs/pretest.

I just succesfully built this version on Solaris 10. The closest
compiler I could find to yours was: "Sun WorkShop 6 update 1 C 5.2
2000/09/11". I configured using:

env CC=/path/to/cc CPP="/path/to/cc -E -Xs" ./configure

If it does not work, please give more detail as to exactly what you
tried and what the result was.

I wasn't saying that at all. I wasn't well enough versed with the
Emacs build procedure to know how to set what it uses for the
preprocessor for cofigure.

I just knew the symbol was missing; I found a kludge way to put it back
that
seemed to work; the root cause seemed to have to do with the
preprocessor, but
I didn't know how to try changing it.

Yes. I defined CPP to be that, and it fully configured, compiled,
linked,
etc. just fine.

I did not try 22.0.97 or 98, but I'll try that if you still want me to.

                                Thanks,

Sorry for the misunderstanding then. As you saw, you just set the
environment variable CPP before running configure (works the same way
for any software that uses configure).

Good to know.

More pretesting is always appreciated, although I'm pretty confident
it will work fine.

    for any software that uses configure).

We changed configure so that the user shouldn't have to specify CPP
manually.  So the latest CVS sources (or the .98 pretest) should
compile ok on Solaris with NO special settings.

Does that work now?

I just tried 22.0.98.

It mostly worked. It worked to the extent that configure seems to
do recognize the existence of header files that previously had problems,
and it seemed to properly identify the system as having ANSI header
files.
And emacs was able to compile and be built successfully.

However, there were somethings printed that caused me some concern.
I'm including all the output below.

I noted the following
1: There are two places where it says
   checking how to run the C preprocessor... /usr/ccs/lib/cpp
rather than cc -E -Xs.
2: It gives this error
   "/usr/include/sys/isa_defs.h", line 500: undefined control
which was indicative to me, before, of the C preprocessor not
having __sparc defined. That was a place that had trouble many times.
3: There are a bunch of places with warnings like the following:
  configure: WARNING: sys/time.h: accepted by the compiler, rejected by
the preprocessor!
  configure: WARNING: sys/time.h: proceeding with the compiler's result

                                Thanks,

Well, that is a very limited fix. It only works if you call the Sun
compiler as /opt/SUNWspro/bin/cc, which I guess is the most common
situation. If you call the same compiler by any other name, it does
not work. Obviously this should be improved, but I think it should
wait till after the release (it may be that /usr/lib/cpp is no longer
the best default CPP for Solaris, I don't know).

The solution (manually specifying CPP for this particular compiler) is
already clearly documented in PROBLEMS and MACHINES.

You can find the solution to all these problems in the etc/PROBLEMS
file. It will basically tell you to manually set CPP="cc -E -Xs". I'm
sorry that the auto-detection is not yet perfect.

Re: Configure/compile failure on Solaris 10 Sparc Ultra 25

    I noted the following
    1: There are two places where it says
       checking how to run the C preprocessor... /usr/ccs/lib/cpp
    rather than cc -E -Xs.
    2: It gives this error
       "/usr/include/sys/isa_defs.h", line 500: undefined control
    which was indicative to me, before, of the C preprocessor not
    having __sparc defined. That was a place that had trouble many times.
    3: There are a bunch of places with warnings like the following:
      configure: WARNING: sys/time.h: accepted by the compiler, rejected by
    the preprocessor!
      configure: WARNING: sys/time.h: proceeding with the compiler's result

We don't need to fix these now, so let's not try.  It would be nice to
fix them later, but only Solaris users can figure out how to do that.

I have a fix for after the release (non-essential changes to
configure.in should not be installed at this stage IMO).
