Actually, you want to stick to just the Requires: definitions, this is not appropriate work for scriptlets. A .so.X dependancy is valid, as it is something that the package providing it will say it provides. # yum whatprovides libQtCore.so.4 Loaded plugins: downloadonly, rhnplugin, security Excluding Packages in global exclude list Finished qt4-4.2.1-1.i386 : The shared library for the Qt GUI toolkit Repo : rhel-x86_64-server-5 Matched from: Other : libQtCore.so.4 However, you shouldn't have to define these requires, as RPM will usually evaluate your code and package to determine most dependancies. RPM itself will not resolve those dependancies for you, that is where yum comes in. RPM will just tell you what it needs, and you have to go find it yourself. Yum will evaluate the dependancies against all of its available packages to find those for you. Installation of your package will work as long as the following is true: 1: your package lists its proper requirements 2: yum is used to install it 3: the system has access to a repository that can meet those requirements. What seems to be happening to you use that you are installing your myApplication RPM manually, and it tells you what you need. Try doing the following: yum install myApplication-1.0-1.x86_64.rpm -greg rpm-list-bounces@xxxxxxxxxxxxx wrote on 07/14/2011 09:17:09 AM: > The dependencies in RPM are only meaningful when it comes to > packages (and virtual resources) that are in the RPM DB. > > If you say "Requires: libQtCore.so.4", RPM thinks there is another > RPM package called libQtCore.so.4 that has to be installed prior to > this and it checks its database and it doesn't find it, hence the error. > > What you really want is file dependency.
