Creating symlink in /usr/bin when creating an RPM

rpm

I'm creating an RPM for an application that doesn't already have one. I've got it building and installing fine in the /opt directory using $RPM_BUILD_ROOT, but I would also like to create a couple symlinks in /usr/bin so that the application is available on the path. All of my attempts to do this have yielded "permission denied" errors because I'm running rpmbuild as a non-root user and it's not allowed to create files in /usr/bin/.

Here's my current .spec file:

Solution 1:

ln -sf /opt/bupc2.8/bin/upcc ${RPM_BUILD_ROOT}/%{_bindir}

The link needs to be created in the %build section and it also needs to point to where you're installing the RPM.

Before creating the link make sure that the destination directory exists, i.e. ${RPM_BUILD_ROOT}/%{_bindir}. You can use mkdir or install -d for this.

Solution 2:

macro %{__ln_s} is good also

example add symbolic link post install:

%post
%{__ln_s} -f %{_bindir}/exec %{_bindir}/exec2

example remove symbolic link uninstall:

%postun
case "$1" in
  0) # last one out put out the lights
    rm -f %{_bindir}/exec2
  ;;
esac

The case statement ensures that the file is only removed on uninstall, and not upgrade, downgrade, or reinstall. RPM %postun for the old package runs after %post for the new package (even if that's the same version).
