How would anyone even begin to help with this email content ?

Okay, so let's see, so you're running Debian Linux on a DEC alpha and you
are trying to bootstrap GCC 4.6.0 while using GCC 3.3.6 with binutils
maybe maybe not and your configure line was black magic while facing east
with a dead cat under a rising moon ?

My guess is that you need to face west.

Try again with some content please !

    I didn't get a log of stderr. I wish I had it turned on now. I'm using 
an old RH 9 for the i686 and binutils-2.21 along with gcc-3.3.6. I have have 
gmp mpfc and mpc all installed and I am using make-3.82. I was rather 
surprised when it broke. If I try again I will get a stderr log.

Couldn't you have used a pencil to write down the actual text of the error?


Was it this error: http://gcc.gnu.org/wiki/FAQ#configure_suffix ?
Did you read the installation docs about --with-gmp and ensuring the
dynamic linker can find libgmp etc?

    Isn't the dynamic linker, ld.so and ld-linux.so2 the same thing?

Yes.

But ld is not the same thing as ld.so and my point is that ld might
have been able to find the libraries, but ld.so could not.

But this still seems like a waste of time until you know what the
actual error was.  I still suggest looking in
$target/libgcc/config.log to see if it's in there.

    Ok but I have another question concerning gcc. I would like to have 2 
compilers. A default and one perhaps in /usr/local or another directory. How 
can I switch back and forth between which compiler I want?

The same way you'd choose between any two programs in different locations.

You could adjust your $PATH or write a script which calls the one you want.

I have a handful of versions installed in ~/gcc/ and invoke them via a
script like

#!/bin/bash
: ${ver:=4.7}
: ${libdir:=lib64}
$HOME/gcc/$ver/bin/g++ -Wl,-rpath,$HOME/gcc/$ver/$libdir -Wall -g "$@"

When you have many versions, it may be more convenient to add a spec file 
that does the rpath thing. This way you can call any g++ in any way 
without bothering with wrappers and without risk.

I often don't want to use -rpath at all.  Now and then I need to
compile with one version and run against a different libstdc++.so to
ensure I haven't broken the ABI, so I mix and match g++ and
libstdc++.so versions.  But that's not something most people will ever
need to do. So optional wrapper scripts work for me.  YMMV.

    I see in .bash_profile that there is a PATH variable set. I have to put 
all my binaries in /usr to get the shell to recognize it. I know nothing 
about bash and would like to run a script that would allow me to simply run 
a script that would switch back and forth between compilers, assemblers, and 
the linker. Maybe 2 scripts. But I can't find the file that lists all my 
path data. env shows the path as does echo $PATH. I always log in as root 
anyway. If I want single user mode I add init=/bin/bash to the kernel switch 
of grub.

I thought it was "widely known" that under a rising moon, the cat HAD
to at least be on life support. It could not be completely dead?!?

Can you just login remotely with an xterm or better yet fire up screen
with session logging and then go to a fresh clean directory. Then let's
try a boot strap again and this time everything gets logged.

wdyt ?

    Nope. Don't have X on my system. Never installed it and removed what few 
directories were left. I have xfree86 binaries but they are kind of old and 
want an even newer glibc than I have I believe. But I can still get errors 
logged with the shell.

gcc-4.6.0 breaks

[Bill Cunningham]

    My gcc-4.6.0 compilation after compiling for quite some time decided to 
break with an error to stderr of something like not recognized object files. 
I am compiling with gcc-3.3.6. This can sure be nerve racking. Does anyone 
know what this means?
