[Buildroot] portmap build error

[mike sander]

Hi All,  

I am getting link error trying to build portmap with yesterdays (Oct 22) 
snapshot.  I have successfully built this on an earlier buildroot (28 
April 2008).   See below for buildlog.

I have enabled RPC in top level buildrott menuconfig as well as checking 
uclib & busybox.  I think the settings look correct.  The  RPC related 
settings are consistent with my earlier buildroot.

Taking svc_sendreply for example.  This is defined in 
toolchain_build_arm/uClibc-0.9.29/libc/rpc/svc.c.   This function (and 
others I suspect are "guarded" by 
"libc_hidden_proto(svc_sendreply)".     I have tried to investigate the 
processing for libc_hidden_proto... but not making much progress.    In 
build_arm/staging_dir/usr/include/libc-symbols.h, the macro 
libc_hidden_proto is declared.  It does the following:

#if (defined __GNUC__ && \
  (defined __GNUC_MINOR__ && ( __GNUC__ >= 3 && __GNUC_MINOR__ >= 3 ) \
   || __GNUC__ >= 4)) || defined __ICC
# define attribute_hidden __attribute__ ((visibility ("hidden")))
# define __hidden_proto_hiddenattr(attrs...) __attribute__ ((visibility 
("hidden"), ##attrs))
#else
# define attribute_hidden
# define __hidden_proto_hiddenattr(attrs...)
#endif

Given the GNUC checks  I thought there might be something with gcc 
configurations,


The new snapshot is using gcc 4.2.4, whereas the older buildroot was 
using 4.2.3.  I have checked the gcc config options between these two 
buildroots and I cannot see any differences.  I have appended the output 
from "gcc -v" in case there is something important.

My target is arm at91sam9260ek in case this is pertinent.

Anyone have any suggestions?   Has anything changes with regard to 
libc_hidden_proto in recent months?   Maybe I have missed a config 
option somewhere?    I suspect it is something basic as RPC is needed 
for nfs.

I can provide other info if needed.

Thanks in advance.

Regards.

Mike
