Bootstrap proceeds fine until near the finish, in building libstdc++, I get

Using the same source directory and the same version toolchain on
i686-pc-linux-gnu results in a succesful bootstrap, when configured thus:
../trunk/configure --prefix=/usr/local/gcc-svn --enable-languages=c,c++,fortran

My last succesful build on on x86_64-pc-linux-gnu was:
 $ /usr/local/gcc-svn/gfortran --version
GNU Fortran 95 (GCC) 4.3.0 20070114 (experimental)
Copyright (C) 2006 Free Software Foundation, Inc.

I suspect this may be a glibc problem as the version of glibc I have is later
than my last successful build of gcc-4.3


Roger.

Frankly, I have no idea what to do with this... Certainly lately we have got
plenty of succesful builds on x86_64-linux and other linux platforms (just look
to testresults). Something mysterious is going on during the build:
bits/c++locale.h includes cstdio which then doesn't find the normal stdio.h
facilities in the global namespace?!? Maybe submitter could attempt narrowing
the problem somehow, for example by building snapshots older and newer...

I am having the exact same problem.

I've tried a few things, tried building in a stable chroot with glibc-2.4
(since my box is mainly unstable with glibc-2.5 and hashstyle) but got the
exact same error. gcc-4.2 snapshots all the way to 20070305 build fine on both
boxes.

Does anyone have any ideas?

Well Ahmed, right now you can't possibly see the exact same error, because
stl_algobase.h does *not* include <iosfwd> anymore... Please provide more info.
Thanks.

My error seems quite similar (with profiledbootstrap and bootstrap too). Older
snapshots have the same issue.

I'm using latest glibc-2.5.90.20070214.

Thanks, but *how much* older, exactly, we must pin-point the exact source of
this problem.

> I'm using latest glibc-2.5.90.20070214.

Can you try with an official release. Really we need to reduce the number of
independent variables, because, as far as I can see, at this point it can be
anything, maybe glibc too. In the reports, on the C++ library side things don't
make sense to me, frankly: <cstdio> just includes <stdio.h> and then there are
the using from the global namespace. And of course nobody among the develepors
is seeing the issue...

I'm trying to CC Jakub as a glibc man, just in case...

People encountering this kind of problem should check whether this trivial C++
snippet compiles:

/////////

#include <stdio.h>

#undef clearerr

namespace my
{
  using ::clearerr;
}

/////////

because really, in that place the build isn't doing much else...

------- Comment #8 from pcarlini at suse dot de  2007-03-11 13:03 -------
Then this snippet could be also useful, just in case we are doing something
wrong in the configury (I doubt it)

//////////////

#include <stdio.h>
#include <bits/c++config.h>

#undef clearerr

_GLIBCXX_BEGIN_NAMESPACE(std)

  using ::clearerr;

_GLIBCXX_END_NAMESPACE

Oh well, if the build really failed <bits/c++config.h> has not been installed,
then include it from the exact place where is available in the build dir.

------- Comment #10 from pcarlini at suse dot de  2007-03-11 13:14 -------
In c++config we have the below lines, which I never noriced before, I wonder
whether can cause problems given the our current framework (in the future is
another matter...)

Note hovewer, that currently __cplusplus in the official GNU tree at least is
still *1*. Is it possible that only *Gentoo* GCC has an external patch defining
__cplusplus as 199711L???

Paolo.

// Macro used to indicate that the native "C" includes, when compiled
// as "C++", have declarations in namespace std and not the global
// namespace. Note, this is unrelated to possible "C" compatibility
// includes that inject C90/C99 names into the global namespace.
// XXX May not be necessary
#if __cplusplus == 199711L
# define _GLIBCXX_NAMESPACE_C 1
#endif

But that doesn't matter, because the newly built FSF GCC still defines
__cplusplus as 1 (in licpp/init.c, by the way). I'm lost... We badly need
details about the behavior of the two snippets, a time-range for the appearance
of the problem, anything to restrict the number of possibilities...

Those 2 snippets working fine here and printf("%d",__cplusplus); says still
"1".

Ok, can we know when exactly this bootstrap problem appeared? Nobody among the
developers is seeing it, I repeat, we can't reproduce it, and if the submitters
are not going to help more, much more, the problem cannot be fixed, this must
be clear.

I cannot say *how much* older, because snapshots older than about 3 weeks
failed with internal error (with profiledbootstrap) and with this error
http://gcc.gnu.org/ml/gcc-patches/2006-02/msg00449.html (with bootstrap). Only
last 3 weekly snapshots didn't fail until libstdc++ building.

Maybe other submitters have better image when it firstly appeared, but as I
said only few last weekly snapshots was trying to build libstdc++.

I'm downgrading glibc to latest official release.

Thanks anyway

downgrading glibc didn't that trick but now() I have successfully builded
latest snapshot with this "patch":

I see, weird, I'm going to add Benjamin in CC, he added very recently the
c_global files and I'm not familiar with #include_next...

I can confirm this patch works on an amd64 gentoo sytem too.

And what happens if you just change that #include_next to #include <stdio.h>,
that would be useful in understanding the issue and how much of it has to do
with #include_next (note that, at the moment, as far as I can see, the
#include_next special features are still not used)
