How to build binary rpm package from srpms in CentOS or RHEL ?

In this article we will look how to create RPM packages in redhat or centos operating environment using the source RPM package i.e. from .src.rpm package.

For this purpose, you can download any src.rpm package and build the binary .rpm package.

1. Download any .src.rpm package.
For example:- I have download the calculator i.e. bc command src rpm.

[root@nglinux ~]# mkdir rpm_test; cd rpm_test/

### Download some .src.rpm package.
[root@nglinux rpm_test]# wget http://ftp.redhat.com/pub/redhat/linux/enterprise/6Client/en/os/SRPMS/bc-1.06.95-1.el6.src.rpm --no-check-certificate

### Package is now downloaded
[root@nglinux rpm_test]# ls
bc-1.06.95-1.el6.src.rpm  vim-7.4.326-11.1.src.rpm
[root@nglinux rpm_test]# 

2. Install rpmbuild utility to build rpm binaries.

[root@nglinux ~]# yum install rpm-build

### Creating directory that contains rpm builds or sources.
[root@nglinux ~]# mkdir rpminstall

4. Install the source rpm

5. Checking the SPEC file.

[root@nglinux rpm_test]# cd ../rpminstall/SPECS/
[root@nglinux SPECS]# ls

[root@nglinux SPECS]# 

6. Execute the preparation stage from the spec file to verify if everything is fine with package dependencies.

[root@nglinux SPECS]# rpmbuild -bp bc.spec 
error: Failed build dependencies:
	readline-devel is needed by bc-1.06.95-1.el6.i686

10. Verify if the packages are created successfully.

[root@nglinux SPECS]# ls -l ../RPMS/i686/
total 268
-rw-r--r--. 1 root root 107148 Feb  2 09:48 bc-1.06.95-1.el6.i686.rpm

We used to perform below steps ideally to build the RPM package.
1. Executing the %prep section.

[root@nglinux SPECS]# rpmbuild -bp bc.spec 
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.JQ0ktq
+ umask 022
+ cd /root/rpminstall/BUILD
+ LANG=C

2. Executing the %build section.(i.e. make command)

[root@nglinux SPECS]# rpmbuild -bc bc.spec 
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.oPzRtU
+ umask 022
+ cd /root/rpminstall/BUILD
+ LANG=C
+ export LANG
+ unset DISPLAY
+ cd /root/rpminstall/BUILD

3. Executing %install section (equivalent to make install).

[root@nglinux SPECS]# rpmbuild -bi bc.spec 
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.eYD72q
+ umask 022
+ cd /root/rpminstall/BUILD
+ LANG=C

4. Executing the binary build process.

[root@nglinux SPECS]# rpmbuild -bb bc.spec 
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.FPAn3y
+ umask 022
+ cd /root/rpminstall/BUILD

However as we have seen above, the build command also executes all stages of pre build, compile, and make install. Hence for some packages we can skip above steps and directly build the package i.e. only last 4th step would be enough.
