What's going wrong? The source (it's a simple 1-file program) and Makefile are available at:
http://assorted.svn.sourceforge.net/viewvc/assorted/hash-join/trunk/src/
In particular, the build command is:
g++ -Wall -lprofiler -lpthread -o hashjoin-pg hashjoin.cc -g -pg
Thanks in advance for any help.
Michael
How can I reproduce it? I don't have -lprofiler. I got
bash-3.2$ g++ -Wall -lpthread -o hashjoin-pg hashjoin.cc -g -pg bash-3.2$ ./hashjoin-pg
hashjoin <ncpus> <movies> <actresses>
bash-3.2$
