Subject: [Buildroot] Add rt squarewave example in buildroot

Hi,
I've compiled and configured the 3.0.14 kernel with rt patch?
in buildroot 11-2011.
I'm trying to build the rt example "squarewave"? in buildroot.
When I launch "make" I obtain the following error:
buildrootfolder/output/host/usr/bin/i586-unknown-linux-uclibc-gcc -c \
rtpatchonoff.c
buildrootfolder/output/host/usr/bin/i586-unknown-linux-uclibc-gcc \
rtpatchonoff.o
-o rtpatchonoff -lrt -Wall
rtpatchonoff.o: In function `main':
rtpatchonoff.c:(.text+0x176): undefined reference to `clock_nanosleep'
collect2: ld returned 1 exit status
make[1]: *** [rtpatchonoff] Errore 1
...
The makefile included in the package rtpatchonoff is:
[makefile]
all: rtpatchonoff -lrt
rtpatchonoff: rtpatchonoff.o -lrt
$(CC) rtpatchonoff.o -o rtpatchonoff -lrt -Wall
rtpatchonoff.o: rtpatchonoff.c
$(CC) -c rtpatchonoff.c
clean:
rm -f rtpatchonoff
[/makefile]
The .mk file is:
[mk]
RTPATCHONOFF_VERSION = 1.0
RTPATCHONOFF_SOURCE = rtpatchonoff-$(RTPATCHONOFF_VERSION).tar.gz
RTPATCHONOFF_SITE = http://nonesiste.com
define RTPATCHONOFF_BUILD_CMDS
$(MAKE) CC=$(TARGET_CC) LD=$(TARGET_LD) -C $(@D) all
endef
define RTPATCHONOFF_INSTALL_TARGET_CMDS
$(INSTALL) -D -m 0755 $(@D)/rtpatchonoff $(TARGET_DIR)/usr/bin
endef
$(eval $(call GENTARGETS,package,rtpatchonoff))
[/mk]
Where is the problem?
clock_nanosleep is defined in
buildrootfolder/output/toolchain/uClibc-0.9.32/librt/clock_nanosleep.c
