Jon,

So now i have the following requires:

Requires:       python-devel.i386
Requires:       postgresql84-server.i386
Requires:       postgresql84-python.i386

and the following BuildRequires:

BuildRequires: gcc = 4.1.2
BuildRequires: make >= 3.81
BuildRequires: postgresql84-devel = 8.4.9

and i get rpm buid fine, and get the following message:

Requires: /bin/bash /usr/bin/env libc.so.6 libc.so.6(GLIBC_2.0) libc.so.6(GLIBC_2.1) libc.so.6(GLIBC_2.2) libc.so.6(GLIBC_2.3) libnsl.so.1 libpq.so.5 libpthread.so.0 libpthread.so.0(GLIBC_2.0) libpthread.so.0(GLIBC_2.1) libpthread.so.0(GLIBC_2.2) librt.so.1 postgresql84-python.i386 postgresql84-server.i386 python(abi) = 2.4 python-devel.i386 rtld(GNU_HASH)

So now when i install this rpm via the "rpm -ivh myapplication.rpm"

i will get Warnings, IF the Requires are not installed

and if i do "yum install myapplication", it will majically install the pre-requisites ? correct ?

Queation is how would yum KNOW "myappliction"

Thanks,

-Kamal.

For build time, BuildRequires. For runtime, Requires.
