[openib-general] Re: [PATCH][DAPL] make dapl build outside of kernel tree

[James Lentini]

Tom,

Did you try building using the method described in the README file?

svn/gen2/users/jlentini/linux-kernel/README

The procedure there has been working for me. I'd rather continue using 
it than change. I like the idea that the build setup is exactly as it 
would be if it were part of the trunk.
