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'
traceback:
main::check_host_clobber:2671
main::build_rpm:906
main::f_buildrpms:980
main:560
===================================
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.
