How to supress -Werror=pointer-to-int-cast and -Werror=address kind of errors in Linux

How to supress -Werror=pointer-to-int-cast and -Werror=address kind of errors in Linux?

I know below are options to use for suppressing the above errors.

-Wno-error=address
-Wno-pointer-to-int-cast

But my question is how to use them or where to edit the compiler settings as I am building a large project.

If you are using gcc, consider the following :

  1. You can simply compile your program using :
    gcc -o obj src_file

    src_file : *.c ( any file name with ".c" extension )

  2. If you are using Makefiles, then

    #SRC stands for source file
    #OBJ stands for object file
    SRC = file.c
    OBJ = file
    CFLAGS = -Wall # do not include the -Werror flag, otherwise warnings will be
    # treated as errors.
    $(OBJ) : $(SRC)
    gcc $(CFLAGS) -o $(OBJ) $(SRC)

Put them in CFLAGS if you are using a standard Makefile build system.

If it's an autoconf project, put it in Makefile.am like this:

CFLAGS = -Wno-error=address -Wno-pointer-to-int-cast

If you're using some other build system, it needs to be passed to gcc command line when compiling .c files to .o.

If it's an existing package that uses autoconf, you can pass it to ./configure like this:

$ ./configure --extra-cflags='-Wno-error=address -Wno-pointer-to-int-cast'

Other autoconf based projects take it from the environment instead of (or in addition to) --extra-cflags:

$ CFLAGS='-Wno-error=address -Wno-pointer-to-int-cast' ./configure --any-other-options-you-need
