I thought I had all the tools I needed for this, but it seems something is missing. When I build the 2.6.18-8.1.3 kernel from source, I get this error: extracting debug info from /var/tmp/kernel-2.6.18-8.el5.trace-root/usr/src/kernels/2.6.18-8.el5.trace-x86_64/scripts/conmakehash extracting debug info from /var/tmp/kernel-2.6.18-8.el5.trace-root/usr/lib/debug/lib/modules/2.6.18-8.el5.trace/vmlinux cpio: kernel-2.6.18/linux-2.6.18.x86_64/<built-in>: No such file or directory 187199 blocks + /usr/lib/rpm/check-rpaths /usr/lib/rpm/check-buildroot /var/tmp/rpm-tmp.77254: line 62: /usr/lib/rpm/check-rpaths: No such file or directory error: Bad exit status from /var/tmp/rpm-tmp.77254 (%install) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.77254 (%install) Sure enough, neither of the two check- files exist, but I'm not sure which package I'm missing that would contain them. I thought I had selected all the right development packafges during install and with yum, and google has not been my friend on this one. yum grouplist Loading "protectbase" plugin Loading "installonlyn" plugin Setting up Group Process Setting up repositories Installed Groups: Office/Productivity Development Libraries Editors System Tools GNOME Software Development Text-based Internet GNOME Desktop Environment Dialup Networking Support Authoring and Publishing Network Servers Legacy Software Development Java Legacy Software Support X Window System Graphics Web Server Windows File Server Printing Support Mail Server Server Configuration Tools Sound and Video Administration Tools Yum Utilities Graphical Internet Available Groups: Engineering and Scientific MySQL Database X Software Development Virtualization Legacy Network Server DNS Name Server FTP Server Games and Entertainment XFCE-4.4 Java Development Emacs Ruby KDE Software Development KDE (K Desktop Environment) PostgreSQL Database News Server Development Tools FreeNX and NX Done (Funny thing - I tried to do 'yum groupinstall "Development Tools"', which I did shortly after initial installation, and it tells me that they're alreayd installed - someone else had a question about this earlier today, too.) I also tried: yum list | grep rpm and got this: redhat-rpm-config.noarch 8.0.45-17.el5.centos installed rpm.x86_64 4.4.2-37.el5 installed rpm-build.x86_64 4.4.2-37.el5 installed rpm-devel.i386 4.4.2-37.el5 installed rpm-devel.x86_64 4.4.2-37.el5 installed rpm-libs.i386 4.4.2-37.el5 installed rpm-libs.x86_64 4.4.2-37.el5 installed rpm-python.x86_64 4.4.2-37.el5 installed rpmforge-release.x86_64 0.3.6-1.el5.rf installed Since there's no current wiki on building kernels for 5.0 (or if it is current, I have already been through all those steps and yum tells me there's nothing to do), can someone point me at what I don't have so I can get it and get on with it?
