First, I must say I believe this might be a problem related to RH7.0
I have updated all gcc and libstdc stuff per RH errata.

[root@lewis /root]# rpm -q gcc
gcc-2.96-69
[root@lewis /root]# gcc --version
2.96
 [root@lewis /root]# automake --version
automake (GNU automake) 1.4
[root@lewis /root]# /sbin/ldconfig --version
ldconfig (GNU libc) 2.2 
[root@lewis /root]# rpm -q binutils
binutils-2.10.0.18-1 

I found an email in an archive that referenced running gcc on this file:
[root@lewis /root]# cat hello.cc
int main()
{}   

Which yeilded the following result :
[root@lewis /root]# cat hello.o
ELFÀ4(  U‰å¸]01.01GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.0).symtab.strtab.shstrtab.text.data.bss.note.comment
!@@,@2T.‚;(    ¸ñÿ
 
hello.ccgcc2_compiled.mainkonsole

I am unsure where to turn next as RedHat doesn't support the compiler. They
only support the binary programs, (even though the compiler is one).

As a secondary note here is an example of some of the config.log file errors
that are shown when a real program is configured:

I have reinstalled all the lates rpm's with respect to binutils, gcc and libc,
libstdc. I have even tried the snapshot of gcc from gnu.org. I am really at a
loss here.

Any help would be greatly appreciated.

It looked that way to me as well.

Don't really know enough about this to even comment.

Yes. That and X11. But the only reason I emailed this list is that the exact
same package has worked severel times before. In fact, it worked several times
the same day before it gave up. I am not saying that it is gcc. On the other
hand, gcc is the one that errors and I was hoping someone who knew enough about
it could point me to the real problem.

I believe due to the problems with gcc not being able to find X11 or qt that
there might be a problem with the linker or maybe ldconfig. I believe the
problem might be related to the running of ldconfig to add a lib path
(something I have done several times before without problems).

At any rate, can you give me a clue as to where the real problem might reside?

It's not GCC that errors.  It's the linker, that is part of GNU
binutils, a separate project.

Anyway, if this thing fails at random, you've probably got some
hardware problem.

The part about symlink surely wasn't in the installation instructions.
You don't want to set up a build in such a way that your original gcc
can be trashed.  Test your new compiler in a separate installation from
the original, or before installing.  Then, if you want to replace the
compiler in /usr/bin, reconfigure with -prefix=usr and install.

Yesterday (13.09.2007) I downloaded the full GCC trunk from svn. It
was around 300 mb in size. I followed the installation instructions as
much as I could.
I made objdir on my desktop and I ran :
 /home/ivan/Desktop/gcc/configure --prefix=/usr/local/gcc/gcc- 4.3.0
--enable-shared --enable-threads=posix --enable-tls
--with-gmp=/usr/lib --with-mpfr=/usr/lib

then I ran make bootsrap and went to bed. I didn't have enough
patience to wait for the tests make -k check process and I commited
make install :)
then I symbolically linked gcc , cpp , g++ c++ gccbug gcj gcov
gfortran from :/usr/local/gcc/gcc-4.3.0/bin to /usr/bin
then I simply tried to ./configure a piece of code and the shell said:

checking for C++ compiler default output file name... configure:
error: C++ compiler cannot create executables
See `config.log' for more details.

The config.log points out:

configure:2113: g++    conftest.cc  >&5

configure:2116: $? = 1
