Hi Ricardo, You should be using --define "kernel <version>" option for the rpm build check the kernel version installed using "uname -r" and use the same value as below command line on your shell rpmbuild -ta fuse-2.7.2glfs9.tar.gz --define "kernel <uname -r output>" Please make sure you have kernel source installed. Let us know if this works for you. Regards -- Harshavardhana #gluster - y4m4 Z Research Inc.
