I ran strace and it generated the following output. I am not sure exactly
what it all means. It seems to me that some files are missing. I am unclear
at this point in how to obtain the missing files? Are the missing files
generated by make file or do they come from somewhere else? At any rate it
would appear that the libEBBLibrary.so (highlighted in purple) is there and
is accessed, but there are others that are not showing up? Any ideas?? By
the way William thanks for the strace tip although I am unclear at this
point about how to interpet??
