Hi,
I have a shell file with this content:
How can I execute ./try40.out only in case gcc issues no warning or error ?Code:clear gcc -g -Wall -Wextra -pedantic -std=c11 try40.c -lm -o try40.out ./try40.out

Look at $?
Code:gcc -g -Wall -Wextra -pedantic -std=c11 try40.c -lm -o try40.out if [ $? -eq 0 ]; then ./try40.out ; fi
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Thanks this works in case of error. In case of only warning(s) , try40.out is executed anyway. Maybe turn warnings into errors ? Other solution ?Originally Posted by Salem
-Werror is one way
Redirecting the stderr of the compilation to a file, and checking whether that file is empty is another.
