Sudo and building as non-root

You should normally not be root and you should setup your system to build RPMs as non-root users. For background, see http://fedoranews.org/tchung/rpmbuild/

Having said that, you need to setup sudo in order to follow many commands in these instructions which require root access.

Adding user sipx is recommended since sipx should later run as user sipx.

yum install rpmdevtools
useradd -G wheel sipx
su - sipx
fedora-buildrpmtree

Note: on Fedora 8 the command name changed to "rpmdev-setuptree"

Edit (as root) /etc/sudoers file to add an entry like this for your user (user sipx is shown here):

sipx    ALL=(ALL)       NOPASSWD: ALL

Installing fedora-rpmdevtools on CentOS is a bit more complex as it is not included in the CentOS repository. Do this:

CentOS 4:
yum install gcc-c++ redhat-rpm-config rpm-build
wget http://download.fedora.redhat.com/pub/fedora/linux/extras/4/i386/fedora-rpmdevtools-1.6-1.fc4.noarch.rpm
rpm -i fedora-rpmdevtools-1.6-1.fc4.noarch.rpm
useradd sipx
su - sipx
fedora-buildrpmtree

CentOS 5:
yum install gcc-c++ redhat-rpm-config rpm-build
wget http://mirrors.kernel.org/fedora/extras/5/i386/rpmdevtools-5.3-1.fc5.noarch.rpm
rpm -i rpmdevtools-5.3-1.fc5.noarch.rpm
useradd sipx
su - sipx
fedora-buildrpmtree

Alternatively, create a file ~/.rpmmacros to tell RPM to use your home directory to build RPMs:

~/.rpmmacros
%_topdir      %(echo $HOME)/rpmbuild
%_smp_mflags  -j3
%__arch_install_post   /usr/lib/rpm/check-rpaths   /usr/lib/rpm/check-buildroot

Then create the RPM build directory structure under your home directory:

mkdir -p ~/rpmbuild/{BUILD,SOURCES,RPMS,SRPMS,SPECS}
