Akemi Thanks for the link those are great HowTos. I double checked and have the packages installed. I think the issue is that the kernel source rpm I downloaded (kernel-2.6.32.220.17.1.el6.src.rpm) from the SL 6.2 SRPM is missing some files. Here is a snippet of the errors I get when running make mrproper and make. make mrproper scripts/Makefile.clean:17: /home/raskew1/R15/OS_Slinux/PCS_Source_Files/PS2/Common/2.6.32-220.el6.x86_64.pcs/drivers/infiniband/hw/amso1100/Makefile: No such file or directory make[3]: *** No rule to make target `/home/raskew1/R15/OS_Slinux/PCS_Source_Files/PS2/Common/2.6.32-220.el6.x86_64.pcs/drivers/infiniband/hw/amso1100/Makefile'. make[3]: Failed to remake makefile `/home/raskew1/R15/OS_Slinux/PCS_Source_Files/PS2/Common/2.6.32-220.el6.x86_64.pcs/drivers/infiniband/hw/amso1100/Makefile'. make[2]: *** [drivers/infiniband/hw/amso1100] Error 2 make CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 HOSTCC scripts/basic/fixdep HOSTCC scripts/basic/docproc HOSTCC scripts/basic/hash make[1]: *** No rule to make target `missing-syscalls'. make: *** [prepare0] Error 2 SHIPPED scripts/genksyms/lex.c SHIPPED scripts/genksyms/parse.h SHIPPED scripts/genksyms/keywords.c HOSTCC scripts/genksyms/lex.o SHIPPED scripts/genksyms/parse.c HOSTCC scripts/genksyms/parse.o HOSTLD scripts/genksyms/genksyms CC scripts/mod/empty.o HOSTCC scripts/mod/mk_elfconfig MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/modpost.o HOSTCC scripts/mod/sumversion.o HOSTLD scripts/mod/modpost HOSTCC scripts/mod/mod-extract HOSTCC scripts/selinux/genheaders/genheaders scripts/selinux/genheaders/genheaders.c:13:22: error: classmap.h: No such file or directory scripts/selinux/genheaders/genheaders.c:14:35: error: initial_sid_to_string.h: No such file or directory Also no /usr/src/redhat directory exists after installing (kernel-2.6.32.220.17.1.el6.src.rpm) like I would see if this was a redhat packaged kernel source rpm.

In addition to the "regular" development tools like gcc and make, you will need some additional packages to build SL-6 kernels. For example, hmaccalc zlib-devel binutils-devel elfutils-libelf-devel More details on how to build custom kernels, please see: http://wiki.centos.org/HowTos/Custom_Kernel It should work for SL kernels.
