How to fix "expected identifier or '(' before '{' token" errors?

[Phacer]

When trying to compile I get this

/main.c:30: error: expected identifier or '(' before '{' token
../main.c:31: error: expected identifier or '(' before 'if'
make: *** [main.o] Error 1

SDL_SysWMinfo info;
SDL_VERSION(&info.version);
if ( SDL_GetWMInfo(&info) ) {
  Display *dpy = info.info.x11.display;
  Window win;
 

These are the lines, line 30 and 31 are the second SDL one and the if (... one.

I tried changing anythign around there, but it doesn`t
seem to work. Any ideas?

Thanks!

You have to put a closing brace '}' at the end of the function.

SDL_VERSION is a macro that, in your case, will expand to something like this:

{
    (&info.version)->major = SDL_MAJOR_VERSION;
    (&info.version)->minor = SDL_MINOR_VERSION;
    (&info.version)->patch = SDL_PATCHLEVEL;
}

I think both of the warnings are complaining about the curly braces generated by the macro. I don't see anything wrong here. Perhaps your version of the macro expands to something slightly different than this.

Try the following as an experiment: change line 2 from

SDL_VERSION(&info.version); 

to

do SDL_VERSION(&info.version) while(0);

My suggestion is a travesty -- please don't leave it like that even if the warnings go away.

Which compiler are you using?

Well, somehow the error seems to have gone, and
I don`t know why.
I think it`s crazy, but restarting the pc made it go...?
Anyway, now I get a new error..

cc1plus: warning: command line option "-std=c99" is valid for C/ObjC but not for C++
In file included from ../main.c:20:
../common.h:105:19: error: SDL.h: No such file or directory
In file included from ../common.h:245

even tough I don't have c++ files, nor mentions on
makefile or any of the project files...

The errors aren't gone -- this new problem is masking the old one.

What compiler are you using?
How are you invoking it?

In fact, I was making a silly mistake on my
c sufixes on my makefile =)
Thanks for everyone`s help!
