[SOLVED] How to make rpm auto install dependencies

Issue

I have built two RPM packages

  • proj1-1.0-1.x86_64.rpm
  • libtest1-1.0-1.x86_64.rpm

proj1 depends on the file libtest1.so being present and it is reflected correctly in the RPM packages as seen here:

user@my-pc:~$ rpm -qp --requires proj1-1.0-1.x86_64.rpm
libtest1.so()(64bit)

user@my-pc:~$ rpm -qp --provides libtest1-1.0-1.x86_64.rpm
libtest1.so()(64bit)

The installation of proj1 fails due to a missing dependency.

user@my-pc:~$ rpm -ivh proj1-1.0-1.x86_64.rpm
error: Failed dependencies:
libtest1.so()(64bit) is needed by proj1-1.0-1.x86_64.rpm

How do I ensure that libtest1-1.0-1.x86_64.rpm is installed automatically during the installation of proj1-1.0-1.x86_64.rpm?

I did try the --aid option with rpm -i as described here but it didn't work for me.

Is there any other way?

Thanks for any help.


Solution

Create a (local) repository and use yum to have it resolve the dependencies for you.

The CentOS wiki has a nice page providing a how-to on this. CentOS wiki HowTos/CreateLocalRepos.

Summarized and further minimized (not ideal, but quickest):

  1. Create a directory for you local repository, e.g. /home/user/repo.
  2. Move the RPMs into that directory.

  3. Fix some ownership and filesystem permissions:

    # chown -R root.root /home/user/repo

  4. Install the createrepo package if not installed yet, and run

    # createrepo /home/user/repo
# chmod -R o-w+r /home/user/repo

  5. Create a repository configuration file, e.g. /etc/yum.repos.d/myrepo.repo containing

    [local]
name=My Awesome Repo
baseurl=file:///home/user/repo
enabled=1
gpgcheck=0

  6. Install your package using

    # yum install packagename
