The endless -Werror debate

Davyd: no need to copy all this complex autofoo stuff in your configure.in. Just use gnome-common and put GNOME_COMPILE_WARNINGS(yes) in your configure.in.

I tend to agree that a maintainer should use -Werror if available since it helps catch some nasty bugs. Forcing everyone to use it is another thing.

Doesn't GNOME_COMPILE_WARNINGS do something different?

2. Vincent [site] [2006-02-12@13:04]

Davyd: it adds this:

--enable-compile-warnings=[no/minimum/yes/maximum/error]
Turn on compiler warnings

Every one should compile C (no joke inside) with at least :

-Wall -Wextra (or -W for older compilers) -Werror

I also use on every project :

-fstrict-aliasing -Wshadow -Wcast-align -Wwrite-strings -Wsign-compare -Wno-uninitialized -Wpointer-arith -Wredundant-decls -Wbad-function-cast -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs

and also when I have not too many function pointers with unused parameters, also :
-Wno-unused (helps to keep track of old variable you no longer use, and that you can also clean).

Every one should do that. C is a sharp tool, one should not *hope* it works, and keep every chances on his side.

hey, I meant no -Wno-[...] but the -W[...] settings.
