Hello,

I understand that the program must be compiled using the command:

cc -std=c11 -Wall -Werror -o runml runml.c

But must the translated code produced by the program do the same? Because this would cause issues depending on the ML code written. Such as:

var <- 6
print 7

Since var is not used, Werror would throw an error!

ml-51566.c:14:8: error: unused variable 'var' [-Werror,-Wunused-variable]
double var = 8;
       ^
1 error generated.

This would not be a fault of the project programmer, but of the test itself. Should this be caught by the compiler, or can we compile using cc/gcc instead of the more intensive error checking.

Thanks.

If you want to be 100% sure you can ask Amitava.

You can always do something with var to remove the warning. Literally just do var = var*1 and the warning will go away.

Use gcc without -Werror.

I recall that on my question on this thread (https://secure.csse.uwa.edu.au/run/help2002?p=np&opt=U308) it was proposed that we compile code without -Werror, but even if we just use -Wall it also throws all warnings, is that expected and fine? Here is example:

My sample translated code is: #include <stdio.h> int main(int argc, char *argv[]) { double x; x = 2.3; print 5; return 0; }

I am compiling this translated c code using "cc -std=c11 -Wall -o mycode mycode.c "

I am getting this warning error: warning: variable ‘x’ set but not used [-Wunused-but-set-variable] 6 | double x; | ^ 5

(Note that "5" is printed just fine)

Just multiply x by 1 in the code.

e.g. x = x*1; and the error/warning will go away.
