Indicating Multithreaded Compilation

You can check whether an application is linked to libthread or not by using the ldd command:

demo% CC -mt myprog.cc
demo% ldd a.out
libm.so.1 =>      /usr/lib/libm.so.1
libCrun.so.1 =>   /usr/lib/libCrun.so.1
libw.so.1 =>      /usr/lib/libw.so.1
libthread.so.1 => /usr/lib/libthread.so.1
libc.so.1 =>      /usr/lib/libc.so.1
libdl.so.1 =>     /usr/lib/libdl.so.1
