Re: (Follow-up) Desperate for Help

[Jeffrey Stephens]

Well, I tried something else, and I was getting kind of giddy thinking I
might
have it working, but, alas, still no cigar!  First, after closely
observing the output
with the -v switch, I changed my initial compile command to:

      $ gcc -dynamic-linker /usr/local/lib/ld-linux.so.2 verglibc.c

WOW!!!! All sorts of stuff starts scrolling across the screen faster
than the eye
can see.  It went something like this:

I really thought I had something here. No error messages, and when I
issued an ls command
look
what I got:

Hey, there's an a.out file there! Can this mean success? No way. When I
issued the
command:

$ ./a.out

I got:

bash: ./a.out: No such file or directory

How can this be? The file is there. The execute mode ('x') is set. The
file is 13505
bytes.  This is maddening, and I still need help.

******************End Follow-up************************************

I have spent many hours compiling and installing a new gcc and glibc,
but I still can't get them to work. I have made posts to a number of
news groups, but without success.  You are my last resort. I am cut/and
pasting a post that I made to one of the newsgroups below. I am hoping
you have the time to respond.  Thanks much.

Regards,
Jeff Stephens

I thought I might have discovered my problem when I read the glibc FAQ.
I tried the
following:

$ gcc --dynamic-linker=/usr/local/lib/ld-linux.so.2 verglibc.c

No luck! Got this error.

cc1: Invalid option `-fdynamic-linker=/usr/local/lib/ld-linux.so.2'

Then I tried:

$ gcc -Wl,--dynamic-linker=/usr/local/lib/ld-linux.so.2 verglibc.c
#that's W(small ell)

This doesn't work either!

/usr/local/lib/libc.so.6: undefined reference to
address@hidden'
/usr/local/lib/libc.so.6: undefined reference to address@hidden'
/usr/local/lib/libc.so.6: undefined reference to address@hidden'

Still hoping for some help. Thanks
