I use the following commands to compile my program

g++ -I./ testme.cpp Thread.o -lpthread -lm -lieee

Basically, the main program creates 5 threads and each thread supposes to print out a "hello world" statement. However the main program cannot create all 5 threads for some unknown reason......

Any idea?

pthread_create (thr, NULL, StartRoutine,....);

StartRoutine() is a function invoked in a child thread. The only thing it does is to print out "hello world". I created 5 threads but I see only 2-4 "hello world" statements on my screen....

ur main program is dying out before all other threads finish up.. so there are two ways
once u r finished up doing creation of threads .. do join on each thread.. then it will ensure that ur main program will wait for the threads to finish up their jobs..
look at the usage of pthread_join

OR
in the end of creation of all threads .. and other jobs .. just before ur return statement of main{}
write this
pause()
this will suspend ur main thread ..and to close ur program use ctrl-C
