Hi Bruce, Thanks for your reply. I am workin on RHEL with architecture x86_64. when i searched for libm.* I got a few location, I tried "make: again after exporting these location in LD_LIBRARY_PATH. but i am getting the same error again. I think, i didn't downloaded the appropriate files for installation. Can you tell me the appropriate location to download the topolbuild.
And some precise installation instruction can help me more, as I am not comfortable with linux env. Thanks a lot for your help. WIth regards, Vivek 2009/3/5 Bruce D.
