RE: ping says unknown protocol icmp I have /etc/protocols file.

Hello Jeffrey,


Thanks, indeed it was an issue of having libresolv library

I copied libresolve to /usr/lib when building the ramdisk and
ping works now.

BTW, is there a something equivalent to  ldd in powerpc world, so one
can find out which shared library an executable is linked with?
I have 8xx environment from MontaVista and I don't see ppc_8xx-ldd

Had a similar problem recently.  Sadly, my little brain does not
exactly remember the solution, but I believe the problem was that I
did not have one of the necessary libraries on my ramdisk that allowed
ping to lookup the icmp protocol in the files you mention.

I think it was one of those libresolv* or libnss* libraries.

Yes, ldd is /bin/ldd in the target file system.

Yes, ldd is /bin/ldd in the target file system.

For execution on a development host, I've attached a simple shell script
that does something like ldd.  (ldd actually loads the program, which
won't work for cross-developed programs.)  It must be run from the same
directory as the target architecture objcopy and objdump, and must have
the same prefix (e.g., ppc_8xx-ldd, ppc_8xx-objcopy, ppc_8xx-objdump).

Of course, it would be better if it correctly removed the tmp file, as
the attached version does.  :-/
