Re: 2.6.14-smp kernel headers and sources

Good Morning All,

I was able to locate the OpenSSI 2.6.14 smp sources on the openssi website and installed the deb package into my src directory after which I ran the menuconfig to set the fuse setting. All went fine until I tried to do the "make" on the sources when I get an error message during the compile.

----------------------------------------------------

Are these the correct sources which should compile or are there additional patches that need to be installed?

I am compiling things on my OpenSSI 2.6.14 main node which should be fine.

Thanks and have a great day,
