    Makefile

    Hi,

    when i run the following makefile:

    Code:
    CFLAGS =-O -Wall -Wextra -Wshadow -Wstrict-prototypes \
              -Wmissing-prototypes -Wmissing-declarations \
              -Wmissing-field-initializers -Wredundant-decls -Wunreachable-code
    
    all: server2.o
            gcc -o server server2.o
    
    server2.o: server2.c
            gcc $(CFLAGS) server2.c
    
    clean:
            rm -f core *.o
    i am getting the following error:
    Code:
    gcc: server2.o: No such file or directory
    gcc: no input files
    make: *** [all] Error 1
    could someone point where i am doing it wrong?

    thanks

    This line also needs to include the -c option (compile only) to produce the .o from the .c
    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.

    Or you could remove the line entirely and rely on Make's pattern handling.
