Re: [Swarm-Support] update target in FCall during make

[Scott Christley]

Ken,

The GCC version you are using is being more strict about the declaration matching the definition.  What you can do is update the code in FCall.h to use the id data type:

void updateTarget (id s, id target);

Then change the code in FCall.m and perform a cast, like this:

void

updateTarget (id s, id target)

{

  FCall_c *self = (FCall_c *)s;

Alternatively, maybe you can move the declaration in FCall.h to be at the end of the file, after @interface FCall_c ... @end.  I thought maybe I tried this and it created an error elsewhere.

The second error you got after making the change is because GCC does not know about the FCall_c class, because FCall_c is defined just below that declaration in the file.

cheers

Scott

Hello there,

Does anybody know why the updatetarget function declaration in FCall.h and defobj.h has different arguments from the updatetarget in FCall.m (updatetarget(id call, id target) v.s. updatetarget(FCall_c *self, id target) ) on Swarm2.2?

When running make I keep getting told there's a problem with conflicting types:

FCall.m: At top level:

FCall.m:592: error: conflicting types for 'updateTarget'

../defobj/FCall.h:43: error: previous declaration of 'updateTarget' was here

make[5]: *** [FCall.lo] Error 1

Tried modifying FCall.h and defobj.h so that lines 43 and 1170, respectively, read:

extern void updateTarget (FCall_c *self, id target);

to be consistent with FCall.m.

Whereupon:

./../defobj/defobj.h:1170: error: expected ')' before '*' token

Does anybody know how to get around this? I'm on RH9 Linux and am using gcc-4.1.1...

Thanks in advance,

Ken
