Hello Experts,

Sometime back I have attended one interview in which I was asked the following question: How do you build a RPM from the source?  I couldn't understand the question, so asked. They asked, How will you make your own RPM; instead of using the standard RPM packages.  I had no clue and replied that I don't have any idea.

Now could you please tell how can I do that? Assume that I'm an intermediate in Linux.

Thanks,
Ashok

The rpm pkgs are platform depedable that is  the i386 pkg is onle mached for X86 systems(intel pentium and celeron or AMD)

if we download a src.rpm then we have to build it to our systems platform



Building from a source RPM (SRPM)

Install the .src.rpm file this way:

rpm -i somepackage-1.0-1.src.rpm

This will create files in the SOURCES directory of your RPM building directory tree, and a .spec file in the SPECS directory. (mostly under /usr/src/)

Then go the SPECS directory and give the command to build the RPM:

cd /home/your_userid/rpm/SPECS
rpmbuild -bb somepackage.spec

Give the -ba option instead if you also want to build the SRPM. The binary RPM packages will typically be created in the RPMS/i386 directory (on a PC-based system).
