egcs-1.0.2 installation

egcs-1.0.2 installation

[Markus Sicheneder]

hello,

refering to your installation guide, i just want to inform you that i
have successfully built and installed egcs-1.0.2 on my system.

i have just one further question:
how to build the shared stdc++ libraries. trying the "--enable-shared"
option gave me an error during compilation.

any hint would greatly appreciated.

regards,
	markus sicheneder

What error did it give you?  If you don't tell us the actual error,
then it's hard to suggest any hints on how to fix the problem.

I've successfully built 1.0.2 with --enable-shared on that

jeff, thanks for your answer.
i thought that it was maybe a known problem, so i didn't tell details,
sorry.
as far as i can see, stage1 and stage2 are built without problems. the
following are the very last rows of the build process; where it stops
with an error:

so to me it looks like xgcc cannot find some object files -- but where
should they come from?!
maybe i am just doing a simple mistake, but i followed the INSTALL
instructions very closely: i did a "../configure --prefix=/usr/egcs
--enable-shared" and then a "make bootstrap".

the error does not occur, when i just do a "../configure
--prefix=/usr/egcs"?!

Try building totally outside of the source directory, not as
a subdir of the source tree.

Re: egcs-1.0.2 installation (still problems)

[Markus Sicheneder]

hello,

sorry to bother you guys again, but i still have problems with the
compilation of egcs-1.0.2 on my i586 linux system (just) with the shared
libs.

thanks for the answers so far; your suggestion to avoid the problems
was:

> Try building totally outside of the source directory, not as
> a subdir of the source tree.

so i have the following directorys now:
	/usr/src/egcs-1.0.2
and	/usr/src/egcs-obj

according to the INSTALL guide i did a:
	../egcs-1.0.2/configure --prefix=/usr/egcs --enable-shared
and	make bootstrap-lean (also tried: make bootstrap)
both in the /usr/src/egcs-obj dir.

here is the output of the configure command:
--- snip ----
sichen:/usr/src/egcs-obj # ../egcs-1.0.2/configure --prefix=/usr/egcs

actually i cant find a pic directory -- and my compiler neighter ?!

i am using:\x18
	gcc-2.7.2.1
	bin utilities 2.7.0.3
	make-3.76.1

well, i was able to compile gcc 2.8.0; but as far as i can remember the
shared libraries were compiled indepentendly (this is about 3-4 months
ago -- so i am not absolutely sure). so i think my system isnt really
the problem.

This seems to indicate that you have your object direct _within_ the egcs
sourcetree. Please try the same with an object tree that does not reside
there.

To the egcs guys: INSTALL/CONFIGURE does not state this clearly, should I
submit a patch?

I'd prefer that configure detect and reject this.  A simple-minded
approach might be something along the lines of:

  # The filename used below must not exist in the source directory!
  INOBJ=in-obj

  touch ${object}/${INOBJ}
  if [ find ${srcdir} -name ${INOBJ} ] then
      echo some whine
      exit 1
  fi
  rm -f ${INOBJ}
  ...

However, that might make the configuration process much slower
than it is already (especially on NFS setups?), so a more clever
approach is probably required, e.g. one that actually parses
the text of the relevant pathnames (which might be challenging
when handling non-UNIX systems).

Reason for this is that I feel a general prioritized approach to
dealing with things like this (situations where the software won't
work quite right) looks something like:

  1.  Make it work in that situation.

  2.  Make it detect that situation and reject it as soon as possible
      (ideally, right when the user who creates the situation does so,
      instead of complaining to user B that user A set things up wrong),
      using a nice clear error message.  Document that the situation must
      not occur, as appropriate.

  3.  Document that the situation must not occur.

  4.  Don't cope with it at all, just tell people who complain that
      they screwed up.

I think we all agree that egcs (and gcc?) are at Level 4 right now and
that it's at least fairly easy to move up to Level 3, but if we
can move to Level 2 or 1, I'm all for it.  But I'm not confident
enough in my own skills vis-a-vis portable shell-script programming
to offer a patch myself at this time.

Funny, I recommended we do that internally at Cygnus since new folks
always make the mistake of building in the source tree once.

The idea was to catch it in the toplevel configure and issue a warning
or error.

While I *personally* think it's a great idea, there are some drawbacks:

  * For years folks have been striving to make the gnu tools easier
  to build/install and have been preacing the "tar xzf blah.tar.gz; cd blah;
  configure; make" as all they need to do for most installations.

  Changing configure to only allow building in a separate dir breaks
  that model.

  * What to do about systems that don't have gnu-make.  Yes, we can
  suggest people use it over and over, but some folks always ignore
  that suggestion.   Most of the time vendor makes can't handle building
  outside of the source tree.

Oops, I think I misspoke about "my" idea.  I didn't mean to reject
that kind of configuration; I meant to reject the kind where,
after "cd blah", people do "mkdir obj; ../configure; make".

Indeed I don't want to disallow something that people have used, and
that has worked, for a long time.  Just the one thing that we've
been discussing that doesn't work, but fails in a way that is hard
for people to understand: building in a separate objdir that also
is a subdirectory of the srcdir.

I think the pseudo-sh code I posted earlier is probably easily edited
to accommodate that (e.g. "rm -f ${srcdir}/${INOBJ}" just before
the "find" command, or similar).  But I still assume my code is
a slow, default way to do things.

Sorry for the confusion.

I agree that this should work, if possible in any way.


What originally triggered this thread, however, was the case where someone
would build in a separate tree which is rooted within the source tree.

_This_ we should warn against and, as someone else has suggested, we could
even detect and refuse to build in such a situation.

With this patch, we are at least at Level 3...

In addition to that enhancement I have also removed the reference to
release 1.0.1 twice. As a matter of fact, Jeff started to add a case
distincation for --enable-haifa yesterday, so this is probably the
way to go...

Well, your problem has been  observed already  on Solaris using  Sun's
make, but I've never seen (or heard about) it  on Linux ;-? You should
be able to build everything correctly, if you're  using a builddir not
located  in  srcdir; i.e.  create   a directory  egcs-1.0.2-build as a
sibling directory to egcs-1.0.2.

I've run into similar problems sometimes, couldn't remember the exact
circumstances and so didn't report the problem. What happens here is that
the 'pic' directory doesn't exist.  Create it, and everything works.

horst,

thanks for your hint, but: i've created the pic dir in both the object
and the source directory but the same error occurs :-(

"piclist" is a file containing a list of the .o files that should be
included in the shared library.

It certainly exists on your system because that's how you got the
reference to "pic/cmathi.o".

  > doesnt exist in my sources (or is this list created during build

It is created during the build process.  Somewhere/somehow the

egcs-1.0.2 installation

[Bart Vansegbroeck]

As requested this mail is intended to notify you of the succesfull
installation of egcs-1.0.2 on an intel-486 dx2 computer, running RedHat
4.0 with the 2.0.18 kernel. The installation ran smooth and took about
4h40minutes.
The output of the program config.guess was the single line:
i486-pc-linux-gnulibc1

With kind regards,
Bart Vansegbroeck
