Hi Ignacio, I'm running Centos 4.2 on some machines and just wonder which is the correct procedure to build one of your packages i've fonund in the fedora.ivazquez.net for FC4 but for CentOs for kernel-modules: http://fedora.ivazquez.net/yum/4/i386/SRPMS.ivazquez/kernel-module-qc-usb-0.6.3-0.iva.1.src.rpm http://fedora.ivazquez.net/yum/3/i386/SRPMS.ivazquez/kernel-module-qc-usb-0.6.3-0.iva.2.src.rpm I've tried unsuccesfully (following dag's Faq for rebuilding against the current kernel): # rpmbuild --rebuild --define 'kernel $(uname -r)' --target $(uname -m)\ kernel-module-qc-usb-0.6.3-0.iva.1.src.rpm TIA JJ
