ok, thanks for the reply.

After I typed the command "make", i've got an error message.
bash: make: command not found

# find / -name \*make -print
/usr/share/lib/make
/usr/lib/spell/hashmake
/usr/lib/svr4.make
/usr/lib/lu/lumake
/usr/openwin/bin/imake
/usr/ccs/bin/make
/usr/ccs/lib/svr4.make
/usr/sbin/lumake
/usr/xpg4/bin/make

Have I installed make? or maybe the $PATH is broken, how can I set it in my environment variables?

Thanks,
warren
