Hi,
I'm trying to compile on older Solaris, sparc, without TLS and without ICU.
Compilation currently fails with:
GSSocketStream.m:145: warning: cast increases required alignment of target type
GSSocketStream.m:197: warning: cast increases required alignment of target type
GSSocketStream.m:200: warning: cast increases required alignment of target type
GSSocketStream.m:206: warning: subscript has type `char'
GSSocketStream.m:243: error: dereferencing pointer to incomplete type
GSSocketStream.m: In function `+[GSStreamHandler tryInput:output:]':
GSSocketStream.m:294: warning: cast increases required alignment of target type
GSSocketStream.m: In function `-[GSStreamHandler bye]':
I get really a ton of "warning: cast increases required alignment of target type" on sparc, also when I build on NetBSD.. anyway.
It looks like a problem with IPV6 support/detection? Most probably non INET6 code-path gets rarely tested today.
Is that correct or should the "fallback" be sin_port instead?
in any case, I get the same error, I suppose it is a problem with sockaddr_ind, I suppose this should be sockaddr_in
I just commited this patch:
- ((struct sockaddr_ind*)sin)->sin6_port = GSSwapHostI16ToBig(port);
+ ((struct sockaddr_in*)sin)->sin_port = GSSwapHostI16ToBig(port);
please comment or revert it if you disagree.
Riccardo
