See msg1360

I have the same error (in VAL-4.2.08)  when I run the following:


VAL-4.2.08$ make
g++  -g -Wall -Werror -iquote -I. -ansi -Wall -c pddl+.cpp -o pddl+.o
pddl+.yacc: En la función ‘int yyparse()’:

pddl+.yacc:363:22: error: se convierte al tipo ‘int’ que no es puntero desde
NULL [-Werror=conversion-null]
cc1plus: todos los avisos se tratan como errores

make: *** [pddl+.o] Error 1


How did you fix this?. Thanks

Thanks for the reminder. An e-mail has been sent.

Have you notified Derek?

The error was caused by a missing g++ replacement. The suggested fix indeed fixes 
the problem and has been pushed.

The proposed change seems to haev fixed the first issue, but now I get 
the following error:

I've seen this before on someone else's machine. The solution is to change
"NULL" to "0" in the two mentioned yacc lines.

Can you make the change, see if that fixes it, and then inform Derek so that
this is fixed upstream? (I don't have gcc 4.5 to try this out.)

Steps to reproduce: 

Set CXX := g++-4.5 in the validator's Makefile. Run make in src/VAL.
