Get Dependencies :
# yum install epel-release
# yum install fedora-mgmt
# yum install misdn misdn-devel
# cd /home/
# yum erase epel-release
Prepare the build environment :
# yum install rpm-build
# yum install yum-utils
# yum groupinstall "Development Tools"
I will use the asterisk SRPM :
# cd /home/
# mkdir -p ~/rpmbuild/{BUILD,RPMS,
# echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
# rpm --nomd5 -ivh asterisk-11.14.1-1.src.rpm
# rpm --nomd5 -ivh mISDNuser-2.0.17-9.1.src.rpm
# cd /root/rpmbuild/SPECS
# yum-builddep asterisk11.spec
# yum-builddep misdnuser.spec
# rpmbuild -bp misdnuser.spec
# rpmbuild -ba misdnuser.spec
# cd /root/rpmbuild/RPMS/x86_64
# rpm -Uvh misdnuser*.rpm
# rpmbuild -bp asterisk11.spec
NOTE: This cud stop as u will be asked for dependencies, install them all and then execute the above stated command.
This will build and patch the file. this is where our patch is gonna come up, move to BUILD folder.
# cd /root/rpmbuild/BUILD
You will see a package file like this one :
# ls
asterisk-11.14.1
Now make a backup of this file as we will be needing it to generate our own patch.
# cp -r asterisk-11.14.1/ asterisk-11.14.1-orig
This will result in two file in the BUILD folder, like this :
# ls
asterisk-11.14.1 asterisk-11.14.1-orig
Now move into ur package file
# cd /asterisk-11.14.1
Once inside do the modification to the source of ur need, any type of customization that u require and then pull out of the folder upto BUILD, listed as follows :
# cd /root/rpmbuild/BUILD
Now we make our own patch :
# diff -Naur asterisk-11.14.1-orig/ asterisk-11.14.1/ > my.patch
This will generate our patch file, move it to the SOURCES folder,
diff -Naur asterisk-11.14.1-orig/

# mv my.patch /root/rpmbuild/SOURCES
Now we edit the spec file again and tell the spec file of our patch,
# cd /root/rpmbuild/SPECS
# nano asterisk11.spec
You will find two point at which editing will be required, for example in this case scenario the first one will be like :
....../.../.../.....
Patch09: asterisk-11.3.0-xorcom-
Patch10: asterisk-11.3.0-xorcom-
Patch11: asterisk-11.5.1-chan_allogsm-
Patch12: asterisk-11.11.0-srtp-
Patch13: my.patch
Notice how i placed the patch number 13, this is what we will be adding to spec file. One more entry is required to tell how to apply patch which we will put in like this :
....../.../.../.....
%patch09 -p1
%patch10 -p1
%patch11 -p1
%patch12 -p1
%patch13 -p1
Again indicated in red is the entry which i did to the spec file, now save the spec file and quit it. Now comes the best part :
# rpmbuild -bp asterisk.spec
This will apply your patch and your modded source is now available, now we build our source so that we can install it, this can be done very easily,
# rpmbuild -ba asterisk.spec
This will generate your rpm which will be located in the RPMS folder under your architecture, according to my case it was in :
# cd /root/rpmbuild/RPMS/x86_64
Now to install it we just do this :
# rpm -Uvh asterisk*.rpm
If you get conflicting errors try this :
# rpm -Uvh -force asterisk*.rpm
This marks the end of our tutorial.
