Hello all,


We are using the p4080 sdk, version beta 2.01.

After install the sdk to /p4080, we ran the ./ltib command, after the build ran for half an hour, it exit with error.



Processing: u-boot-p4080


Error: /p4080sdk/ltib-e500mc-20091218//rpm/RPMS/ppc/u-boot-2009.06-14.ppc.rpm would clobber '/p4080sdk/ltib-e500mc-20091218/rootfs/boot'









Finally, we found the error reason as below:


In ltib, the below 3 lines is the error occured location.

[2671]  if( $path !~ m,^(?:/opt|/tmp|/home|$cf->{rfsbase}), ) {
[2672]            die("ERROR: $rpm\nwould clobber '$path'\n");
[2673]        }


We modify the ltib script to print out the $cf->{rfsbase}  and $path,

$cf->{rfsbase}     /p4080sdk/ltib-e500mc-20091218//rootfs

$path                    /p4080sdk/ltib-e500mc-20091218/rootfs/boot


We found that the $cf->{rfsbase} has one more '/' in the output string.

This is the root cause which make the check_host_clobber exit with error.


The $cf->{rfsbase} is defined in line 508 of ltib script.

[508 ] $cf->{rpmroot} = $cf->{rfsbase} = "$cf->{bldbase}/rootfs";


After modify this statement to

[508' ] $cf->{rpmroot} = $cf->{rfsbase} = "$cf->{bldbase}" . "rootfs";

We get the correct $cf->{rfsbase}  output as below

$cf->{rfsbase}     /p4080sdk/ltib-e500mc-20091218/rootfs


After the ltib update, We re-ran the ./ltib script.

"Build Succeded"



Thanks for my colleague huaiguang for the perl support. :smileyvery-happy:
