Wrong way again.... The -lpthread goes on the FINAL link you do with your OBJS. It told you "linking not done" becauce your "-c" is just compiling to the .o file and no libraries are needed for that. All -l library references are when you build the final executable. Michael D. Black Senior Scientist Advanced Analytics Directorate Northrop Grumman Information Systems
