as problem, PPC

[Brett Dikeman]

<grrr>
Ok, I just installed two RPM's from someone who built egcs on the Linux-ppc
platform.(10-26 snapshot I believe.)
After uninstalling gcc and gcc-c++ packages, I installed the two RPM's
containing egcs-c and egcs-c++.  Both installed fine.
I also installed an RPM with binutils-2.8.1.0.11, which went fine as well.

However, every time I compile something, it dies with a fatal error,
reporting that it "can't execute 'as', no such file or directory."
Weeeelll, ok, so I copy /usr/bin/as to
/usr/lib/....etc..../ppc-linux/egcs...etc.../as

well, now it reports:
"can't execute '/usr/lib/<snip>/as', no such file or directory."
(I simlified the paths with ...'s and etc's and <snip>, egcs didn't print
that out :)

So, I get curious:
$/usr/bin/as
bash: /usr/bin/as: no such file or directory

what the???

The only time I've seen this is when I messed up the shabang in a
shell/perl script and bash couldn't execute it, but I've _never_ seen a
binary do this!

Any ideas/suggestions?  Could it be generating this message because it
can't find a shared lib(I thought this was usually very explicitly reported
as something like "missing libraries X, Y, Z")?

I suggest you contact whomever sets up the RPM (I assume these are
some kind of "package install" systems?).

sorry, I thought everyone was familiar with RPM's.
Redhat Package Manager
By RedHat.
Basically, a smart, compressed tarball.  It can run install/removal
scripts, and checks for dependencies(ie, package less-X.yz needs
libncursesX.zy.)
Comes in two flavors: SRPMs(source RPMs) and RPMs(which usually contain the
compiled, end result.)
RPM is a Linux thing, and [S]RPMs are built by anyone who wants to; there
is no rpm head-hauncho :)

As many have pointed out, posting RPMs made by Joe Shmoe to big sites is
like giving Joe Shmoe root access to hundreds or thousands of systems.
Convenience vs. Security.  The age old problem.

Still, I don't understand the message. Oh well.  I'll ask the Linux-pmac
group and see what they say.

There are some RPM's available from Elliott Lee <sopwith@redhat.com> at
< ftp://ftp.cs.cuc.edu/ > (it was announced on this list). These are quite
preliminary at the moment, but we are working on getting out more uptodate
packages. The most valuable package on this site is the dejagnu-RPM (Thanks
Elliott ;-) ).

My current status is:
- gas/binutils snapshot 971102, built as RPM (BTW, can one safely ignore
the "run libtool --finish" message during "make install_root=/tmp/gas
install"?). I haven't tried building with --enable-shared yet, cause my
last version 970915 still failed during install with this option turned on.
I will try to arrange something with Elliott and put the RPM on FTP.

- egcs-971031, still a pain to build, needs a lot of unofficial patches
from Geoffrey Keating, on a standard out-of-the-box Linux/PPC installation
(libc-0.961212) compiling still fails during libio, complaining about a
missing stdio-lock.h. Also the new libg++-2.8.0b6.3 fails during configure
(while symlinking regex.h / rx.h ?).

Ciao,
Franz.

Looks like you've misplaced ld.so.  I wonder if the RPM upgraded your
binutils too?  And the distributer is using glibc2 and you aren't?

What does "objdump -s -j .interp /usr/bin/as" report, if you can?

That was in a seperate RPM.  binutils-2.8.1.0.11.

"bash:/usr/bin/objdump: no such file or directory"

(with or without command arg's.)

It's because of the dynamic linker name.

I compiled that package to use /lib/ld-linux.so.2

The traditional glibc setup is /lib/ld.so.1

Do:
	ln -s ld.so.1 /lib/ld-linux.so.2

/lib/ld.so.1 exists.
Tried linking it to ld.so.
No change; same error.

That can be many things. I need to see

# gcc -v ......

when the binary is built and

# objdump --private xxx

on the resulting binary.
