Re: [Swarm-Support] Install problem on fc3

[Scott Christley]

Jim,

It could be one of two things; either the compiler you have is bad, or 
possibly it is okay but is a newer version with more strict type 
checking.  However I think the real problem is not that warning message 
about setClass, it is the error that happens later.

InputStream.m: At top level:
InputStream.m:428: internal compiler error: in encode_type, at
objc/objc-act.c:7393


Anyways, what you can try is to change the definition in defobj.h to be 
identical to the one in collections.h; however, I'm skeptical of the 
compiler if its producing internal errors.

cheers
Scott
