Cross compiling setup

[Jeff Picciotti]

Hello, having a little trouble remembering what I did in the past and 
thought someone out there might have a suggestion.

A little background...  My small company has developed an arm board in 
house and we have already setup up a couple of rootfs, one for runtime, 
one for debugging and we also setup a cross compiling machine which is a 
fedora 8 box. 

We decided we were going to move our cross compiling machine to another 
server and start fresh and I am having trouble linking the libraries I 
need (the libraries do not exist in my new toolchain, where they do 
exist on the old machine).  I was obviously successful before but I 
can't seem to find my notes. 

I am having trouble remembering if I did anything special to manually 
install the following libraries in /usr/armv5tel-red.../sys-root/lib  
and /usr/armv5tel-red.../sys-root/usr/lib
libglibc-2.0
libgssapi_krb5
libk5crypto
libssl
libkeyutils
some others to. 
I have this feeling I used some rpm tool to do this but maybe not. 
Should these libraries be there by default or can I install the rpms for 
them from the arm repository or how s the correct way to do this? 
Did I copy these files from a rootfs?
I have tried to install to the new toolchain using rpm but I get "cannot 
relocated this rpm".

The guy who setup both machines said that he did not make the new system 
type "sw development" as he did the one we have working so we are 
wondering if this may be an issue that some things are not getting 
installed properly (We feel this is probably not the case).

As for now I simply tar'd up the old toolchain and copied it to the new 
machine and I can compile, but I do need to figure this out for our wiki 
setup pages so any help or thoughts would be greatly appreciated. 

Hopefully you are able to understand my issue...

Also the Fedora-arm wiki is missing a lot of commands,  if you click the 
discussion tab the missing parts can be found there.  Not sure what that 
is about. 

Thanks in advance,

Jeff

I always use rpm2cpio | cpio -i from the top of the sysroot.

Thanks for the quick reply, but sorry to say I am not sure exactly what 
that means.  I did a man on it and as it turns out my old build machine 
has that command but the new machine does not.  Just thought I would 
note that...
Is what you are saying, that you take the target rootfs and put it at 
sysroot?

Thanks

Jeff

If /usr/bin/rpm2cpio is missing you haven't correctly installed rpm, and
I have no idea how that can possibly have happened.

Exactly.  That's how sysroot is supposed to work.

What I do is use this script:

	http://fedora-arm.wantstofly.org/cross/repack_cross.pl

To turn the target (arm) rpm into a noarch rpm with all files
relocated to the sysroot, so that you can 'rpm -i' it on the
host.  It also fixes up file dependencies and such.
