I'm trying to use nfs mount within busybox. This requires mount &
portmap. I am getting a link failure that I cannot figure out.
I have enabled busybox MOUNT, FEATURE_MOUNT_NFS, FEATURE_HAVE_RPC as
well as uclibc UCLIBC_HAS_RPC and top level
CONFIG_BR2_PACKAGE_PORTMAP. I have done a top level "make clean".
Here is the output of top level make. I have even explicitly put the
full path to libc.a in the link line (in portmap Makefile):

Make sure I'm pointing to the right libc.a:
mike at himalia:/home/buildroot$ arm-linux-gcc -print-file-name=libc.a
/home/buildroot/build_arm/staging_dir/usr/lib/libc.a
Using nm, I verified that libc.a does in fact contain 2 of the 3
unresolved external references.
mike at himalia:/home/buildroot$ nm
/home/buildroot/build_arm/staging_dir/usr/lib/libc.a | grep svc_run
svc_run.os:
00000028 T svc_run
mike at himalia:/home/buildroot$ nm
/home/buildroot/build_arm/staging_dir/usr/lib/libc.a | grep svctcp_create
00000354 T svctcp_create
Anyone have any ideas what is going on here?
Thanks in advance.
Mike

I think I may have a solution. After a bit of work with ld --print-map
flag I discovered portmap is using shared libraries (not static as I
thought). The shared lib appeared to be missing svc* functions.
I found that adding svc_run.c to the
buildroot/toolchain_build_arm/uClibc-0.9.29/libc/inet/rpc/Makefile.in
allowed the link step to complete. I do not believe that this is the
proper place for this change as this is in a generated target specific
tree. I have looked to docs & source tree to find the appropriate place
but have been unable.
If someone could point me to the correct location to patch that would be
helpful.
As well, if someone could apply this patch to buildroot that would be
good as well.
Following is a patch to be applied from the following location:
buildroot/toolchain_build_arm/uClibc-0.9.29/libc/inet/rpc. If this is
not a good way to submit a patch, any helpful suggestions would be
appreciated.
