portmap build error

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

Following up from my earlier post. I am still unable to build portmap.

What I have noticed is that the earlier buildroot (april) has these symbols in arm-linux-uclibc/lib/libgcc_s.so. They are not present in the newer buildroot. I am trying to figure out how libgcc is built.

As far as I can tell all RPC related configurations are identical between my two buildroot trees.

Anyone have any ideas?

Thanks,
