Hi All, I am trying to install lustre-1.4.10 on kernel 2.4.31. But unfortunately i found only patch for kernel 2.4.20. I force quilt to install patch 2.4.20 on kernel 2.4.31 and did a quilt refresh and i am still receiving the same error as before. checking if you are running user mode linux for i686... no (asm doesn''t point at asm-um) checking for /usr/src/linux/include/linux/namei.h... no checking if you are using Linux 2.6... no checking that modules can be built at all... yes checking for Linux release... 2.4.31 checking for Lustre release... 2.4.31_200706211018 checking if Linux was built with CONFIG_MODULES... yes checking if Linux was built with CONFIG_MODVERSIONS... no checking if Linux was built with CONFIG_PREEMPT... no checking if Linux was built with CONFIG_KALLSYMS... no configure: error: Lustre requires that CONFIG_KALLSYMS is enabled in your kernel. Please forward me a link where I can get the correct patch version for my kernel. Or any other way to patch my kernel. Thanks Prashant
