Re: gnustep-base on FreeBSD (from ports)

[Fred Kiefer]

I think your compiler is not complaining about sizeof(void*). Instead this 
definition is problematic:

#define GSI_MAP_TABLE_S sizeof(GSI_MAP_TABLE_T)

The error message says why: application of 'sizeof' to interface 
'NSConcreteHashTable' is not supported on this architecture and platform

David just beat me on reporting this. I was trying to dig a bit deeper to see, 
where the actual problem in GNUstep is. And for me it looks like this isn’t one.

The line in GSIMap.h the compiler is complaining looks like this:

#ifndef GSI_MAP_TABLE_S
#define GSI_MAP_TABLE_S sizeof(GSI_MAP_TABLE_T)
#endif

and in NSConcreteMapTable.m we have a few lines before the include of GSIMap.h 
this:

#define GSI_MAP_TABLE_S instanceSize

So there is no reason for the compiler to ever evaluate the line it is 
complaining about.

Maybe I have a different version of the GNUstep code, but if not, you should 
write a bug report to clang.

Cheers
Fred
