RE: [Ltib] RE: Reg ltib

[Stuart Hughes]

Hi Neha,

Don't run in single package mode, gdb has dependencies.  To fix this:

$ rm -rf rpm/BUILD/gdb*
$ ./ltib -m config         : select gdb
$ ./ltib

If that doens't work, them you need to say which platform you're
building for and which version of LTIB (e.g. iso image etc).

Regards, Stuart
