Help with posix.dll

Thanks for reading this post and any subsequent advice.

I got the following message when running a program that contain a posix call.

Note: posix.dll is not found. Do ‘sh setup’ in $CINTSYSDIR/lib/posix directory if you use UNIX.

I followed the given instruction and got the following message:

[timtran@localhost posix]$ sh ./setup

Do ‘make -f Makefile’ to compile the object
gcc -o exten.o -c exten.c
make: *** No rule to make target /usr/local/root/cint/cint', needed byG__c_posix.c’. Stop.

Can some body tell me what the message: “No rule to make target” means? And I need to do to resolve it.

Thanks you agian.
