Re: [Ltib] how to compile an ltib-format app dir without using ltib?

[Stuart Hughes]

Hi Robert,

Try:

$ ./ltib -m shell

This will put you into the same build environment that LTIB has when
it's running the %prep/%build/%install sections of the rpm spec files.
Spoofing will be setup for you.  To exit, type 'exit'.  Take a look at
f_shell in the ltib script to get an idea of what else gets setup for
you.

Regards, Stuart
