When I change “SDL.h” to “SDL/SDL.h” it works without warnings.
Exactly same problem with <SDL.h> and <SDL/SDL.h>. So changing “” into <>
changes nothing in output, but adding ‘SDL/’ fixes warnings.
Could anyone explain why this happen?

“This option is not intended to be useful; it exists only to satisfy

You want -Wall -W, not -pedantic. Libraries aren’t expected to compile
with -pedantic without warnings.

changes nothing in output, but adding ‘SDL/’ fixes warnings.

Not sure, but you probably shouldn’t be using -pedantic to begin with.On Wed, Nov 12, 2003 at 08:54:56PM +0100, Jacek Pop?awski wrote:

I am willing to bet you that <SDL.h> would not produce the warning, but
“SDL.h” would.
Figuring out why gcc will give different warnings for system headers (I
believe <> is defined as being used for them) then it does for program
headers (“”) is left as an exercise for the reader.On Thu, Nov 13, 2003 at 12:05:37AM +0100, Jacek Pop?awski wrote:

I still do not understand why manglement believes that cutting off the
oxygen flow to the brain will INCREASE productivity. The reason they
made that decision is probably because they couldn’t think clearly due
to wearing neckties.

I know this is not serious problem, but I think that it is interesting to find

I can’t actually reproduce the problem (as I don’t have a copy of GCC
installed here), but my guess would be that your search-path is setup so
that “SDL.H” resolves to a different file than “SDL/SDL.H”. Now, I’m not
sure, but I believe adding -H to your G++ command line will make it print
out the include files’ full paths.

If you want to know why gcc has unexpected behavior, you should be
asking on a gcc list, not an SDL list.
Note, also, that you didn’t acknowledge in your first post that
-pedantic turns on bogus warnings and shouldn’t actually be used in
practice, so it’s expected that you’d be told “don’t do that”.On Sat, Nov 15, 2003 at 10:38:56AM +0100, Jacek Pop?awski wrote:

And this is the reason I wrote that I have only one SDL.h file installed.

it print out the include files’ full paths.
I tried that, then compared output with diff - no differences (except warning
message).On Sat, Nov 15, 2003 at 06:14:54PM -0700, John Silicon wrote:
