In the last changes you made, you set a default bool variable in the else
statement. That's why I'm getting a warning message. When I tried changing
the compiler flag it didn't work.


*export CFLAGS="-O2 -Wall -Wno-error"*
Do you have any advice on this subject? Thank you very much in advance.

Does setting the env variable even work?
