compiling udf error help

venkatesh4386@gmail.com

im using linux os 64 when i try to 'BUILD' my udf in fluent i get the error

"cat: log: no such file or directory."

i am able to INTERPRET the same udf in fluent without error.the case and data files are in tha same folder.

when i tried to load it, it gives error msg as

"open_udf_library: no such file or directory"

in the TERMINAL im getting message as

"make: Warning: File `Makefile' has modification time 1.3e+03 s in the future make: warning: Clock skew detected. Your build may be incomplete."

THANKS IN ADVANCE,

VENKAT
