REPOST: compiler error passing method

[Steve Emsley]

Hi,

Kevin ... Thank's for you input. I don't think I've made a typo or not
declared a method prior to using it. However, I may have so I'm now going
to declare the problem as is ...

main.m
#import <simtools.h>
#import "POModel.h"
#import "LightTable.h"

int 
main(int argc, char ** argv) {
  id theTestSwarm, theLightSwarm;
  int i;
  
  initSwarm(argc, argv);

  theLightSwarm = [LightTable create: globalZone];
  theLightSwarm = [theLightSwarm createEnd];

  theTestSwarm = [POModel create: globalZone];
  theTestSwarm = [theTestSwarm createEnd];
  [theTestSwarm setLightSpace: theLightSwarm];
  [theTestSwarm test];
  
  return 0;
}

LightTable.m contains a method bcalled spectral and POModel.m contains
a method called setLightSpace: (id) l

-(void)setLightSpace: (id) l { lightSpace = l; return ; }

where lightSpace is declared type id in POModel.h and setLightSpace is also
declared. However, when I call the method:

-(void) test {
  double tmp;
  tmp = [lightSpace spectral: 50];
  printf("%d\n",tmp);
  return;
}

I get the error message:

OModel.m: In function `_i_POModel__test':
POModel.m:665: warning: cannot find method.
POModel.m:665: warning: return type for `spectral:' defaults to id
POModel.m:665: incompatible types in assignment
POModel.m:666: warning: int format, double arg (arg 2)
make: *** [POModel.o] Error 1


I may be missing something from the swarm code since all I do is use the
main.m as defined and create the classes. It worked OK in testing the class
LightTable (but that class doesn't communicate with any others).

Any suggestions would be extremely helpful ... at least I've still got some
hair left!!

Regard,
Steve.

Life would be so much easier if we could just look at the source code.
