Automatically install build dependencies prior to building an RPM package

Question

I am trying to build a .rpm package. I have just followed the steps to do that. Till now all steps were gone fine but now i just stuck with this step. I just ran the following command and got this error:

rpmbuild -ba asterisk.spec

error: Failed build dependencies:      gtk2-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64     libsrtp-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64     [... more ...]     freetds-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64     uw-imap-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64 

I am using fedora-15. How to resolve this error?

How I do install all depencencies during installation of src.rpm package. Is it possible?

Answer 1

You can use the yum-builddep command from the yum-utils package to install all the build dependencies for a package.

The arguments can either be paths to spec files, paths to source RPMs or the names of packages which exist as source RPMs in a configured repository, for example:

yum-builddep my-package.spec 

or

yum-builddep my-package.src.rpm 

The same thing can be achieved on newer versions of Fedora that use dnf as their package manager by making sure that dnf-plugins-core is installed and then doing:

dnf builddep my-package.spec 

or

dnf builddep my-package.src.rpm 

Answer 2

yum-builddep doesn't seem to work if the mirror you use doesn't serve source RPMs. This may not handle all cases, but it usually works for me:

sudo yum install -y $(<rpmbuild> | fgrep 'is needed by' | awk '{print $1}') 

where <rpmbuild> is your rpmbuild command (e.g., rpmbuild -ba foo.spec).
