Hi People, I have just started building my own RPMS on both Fedora and CentOS and generally things have gone well. Currently I am trying to create RPMS for some commercial software that we have purchased. Step 1 was install the software using its JAVA Based installer ensuring that all files were installed into a particular directory in /usr/local. Step 2 was create a tar file of the resulting files Step 3 Turn this tar file into an RPM using the following spec file Name: mathematica Version: 6.0 Release: 1%{?dist} Summary: Mathematica Group: Development/Tools License: Commercial URL: http://www.wolfram.com/ Source0: mathematica.tar.bz2 BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) AutoReqProv: no #BuildRequires: #Requires: %description Long recognized as the world's most powerful mathematical software system #%prep #%build %install rm -rf $RPM_BUILD_ROOT mkdir -p $RPM_BUILD_ROOT cd $RPM_BUILD_ROOT tar xvjf $RPM_SOURCE_DIR/mathematica.tar.bz2 %clean rm -rf $RPM_BUILD_ROOT %files /usr/local/ %defattr(-,root,root,-) %doc %changelog * Wed Jul 11 2007 SCMS, Waikato University Initial RPM release - Clint Dilks When testing the install phase I use the following command QA_RPATHS=$[ 0x0002 ] rpmbuild -bi mathematica.spec This completes but this message is displayed prelink: /var/tmp/mathematica-6.0-1fc6-root-{user}-/usr/local/Wolfram/Mathematica/6.0/SystemFiles/Libraries/Linux/libPHANToMIO.so.4: at least one of file's dependencies has changed since prelinking If I ignore this and build the RPM completely using rpmbuild -ba mathematica.spec an RPM is created but when I try and install this it fails because the MD5 Sum of the file mentioned above is not correct. Anyone have any idea how to stop the prelink change that is causing the problem ? I assume its a directive similiar to %define __os_install_post %{nil} but I'm unsure exactly what I should be turning off. Thanks Clint
