[meta-freescale] Porting ltib project to yocto by creating a recipe - link questions

Sat Apr 27 11:58:06 PDT 2013

ok so i've added the necessary link flags to link to the libraries but I
get the following error when installing (note I used bitbake <recipe> as
well as bitbake <recipe> -c devshell) The output below is from the latter
method:

ashwin at ashwin1:~/fsl-community-bsp/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/imx6texture-0.1-r0/src$
make install
arm-poky-linux-gnueabi-ld
--sysroot=/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite
 wrapper.o gstcontrol.o glutils.o glplane.o main.o -lgstreamer-0.10
-lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt -lxml2 -lglib-2.0 -lpthread
-lm -lc  -o imxTextureApp
arm-poky-linux-gnueabi-ld: gstcontrol.o: undefined reference to symbol
'__aeabi_unwind_cpp_pr0@@GCC_3.5'
arm-poky-linux-gnueabi-ld: note: '__aeabi_unwind_cpp_pr0@@GCC_3.5' is
defined in DSO
/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite/lib/libgcc_s.so.1
so try adding it to the linker command line
/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite/lib/libgcc_s.so.1:
could not read symbols: Invalid operation
make: *** [install] Error 1

libgcc_s.so is a runtime dependency I believe. How do I resolve this error?
I tried added the following to my recipe but it didn't work:
RDEPENDS_${PN} += "libgcc"

Here is the makefile for reference. I added LFLAGS variable to link to the
necessary libraries

LFLAGS = -lgstreamer-0.10 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt
-lxml2 -lglib-2.0 -lpthread -lm -lc

OBJS = wrapper.o \
 gstcontrol.o \
glutils.o \
glplane.o \
main.o

all: $(OBJS)

install:
$(LD) $(OBJS) $(LFLAGS) -o imxTextureApp

clean:
rm -rf *o
