OpenAFS Warning detection
|
|
-------------------------
|
|
|
|
There's been a concerted effort over the last few years, by many developers,
|
|
to reduce the number of warnings in the OpenAFS tree. In an attempt to
|
|
prevent warnings from creeping back in, we now have the ability to break the
|
|
build when new warnings appear.
|
|
|
|
This is only available for systems with gcc 4.2 or later, and is disabled
|
|
unless the --enable-checking option is supplied to configure. Because we
|
|
can't remove all of the warnings, we permit file by file (and warning by
|
|
warning) disabling of specific warnings. The --enable-checking=all prevents
|
|
this, and errors for any file containing a warning.
|
|
|
|
Disabling warnings
|
|
------------------
|
|
|
|
If warnings are unavoidable in a particular part of the build, they may be
|
|
disabled in an number of ways.
|
|
|
|
You can disable a single warning type in a particular file by using GCC
|
|
pragmas. If a warning can be disabled with a pragma, then the switch to use
|
|
will be listed in the error message you receive from the compiler. Pragmas
|
|
should be wrapped in IGNORE_SOME_GCC_WARNINGS, so that they aren't used
|
|
with non-gcc compilers, and can be disabled if desired. For example:
|
|
#ifdef IGNORE_SOME_GCC_WARNINGS
|
|
# pragma GCC diagnostic warning "-Wold-style-definition"
|
|
#endif
|
|
|
|
If a pragma isn't available for your particular warning, you will need to
|
|
disable all warnings for the file in question. You can do this by supplying
|
|
the autoconf macro @CFLAGS_NOERROR@ in the build options for the file. For
|
|
example:
|
|
lex.yy.o : lex.yy.c y.tab.c
|
|
${CC} -c ${CFLAGS} @CFLAGS_NOERROR@ lex.yy.c
|
|
|
|
If you add a new warning inhibition, please also add it to the list below.
