Is there a way to verify if an application is installed , from within a SPEC file ?
Maybe using %verifyscript section ?

Thanks,

For build time, BuildRequires. For runtime, Requires.

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.

Typically, one does not add architecture specifiers, such as ".i386", to
Requires in a spec file, but relies on package tools to choose packages
made for a compatible architecture. On platforms, where the %_isa macro is
defined,

$ rpm --eval %_isa
(x86-64)

you can use it to create arch-specific Requires:

Requires: python-devel%{?_isa}

Only do it if you feel confident enough, of course.

Publish your packages in a local or remote _repository_ of packages.
Use "createrepo" tool, and point Yum at that repository.
