Make sure you link in the necessary CE libraries with your ARM application.
This is what I had to link in with my ARM application:
export CE_DIR = /opt/dvevm_1_10/codec_engine_1_02/packages
export DSPLINK_DIR= /opt/dvevm_1_10/dsplink_1_30_08_02/packages
export CMEM_DIR = /opt/dvevm_1_10/cmem_1_01/packages
EXTRA_LIBS = $(CE_DIR)/ti/sdo/ce/speech/lib/speech.a470MV \
$(CE_DIR)/ti/sdo/ce/lib/ce.a470MV \
$(CE_DIR)/ti/sdo/ce/node/lib/node.a470MV \
$(CE_DIR)/ti/sdo/ce/utils/trace/lib/TraceUtil.a470MV \
$(CE_DIR)/ti/sdo/ce/bioslog/lib/bioslog.a470MV \
$(CE_DIR)/ti/sdo/ce/osal/lib/osal_dsplink_linux.a470MV \
$(DSPLINK_DIR)/dsplink/gpp/export/BIN/Linux/Davinci/RELEASE/dsplink.lib \
$(CMEM_DIR)/ti/sdo/linuxutils/cmem/lib/cmem.a \
$(CE_DIR)/ti/sdo/ce/osal/alg/lib/alg.a470MV \
$(CE_DIR)/ti/sdo/ce/trace/lib/gt.a470MV
myapp.out :
$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $(OBJ) $(LIBS) $(EXTRA_LIBS)

Subject: Sementation fault
Hi All,
I am developing application on Davinci. I try to use codec engine APIs, and
I face few problems after integrating Codec engine in my application. I have
listed down the problems below 1. In my application first i called
CERuntime_init function. When I call Engine_open API it gives errors
undefined reference to `Engine_config" and undefined reference to `GT" 2. So
i declared above variables in my application to remove these erros(i think
its not the right way) and build the application successfully.3.And when I
run the application I got a Segmentation Fault in Engine_open.
I have linked all codec related libraries properly. You can also refer the
request posted by someone at the link
http://linux.omap.com/pipermail/davinci-linux-open-source/2006-September/000895.html
,
same problem I am facing here. Even though I called CERuntime_init then also
I am getting this error.
Error mesg:
Program received signal SIGSEGV, Segmentation fault.0x0002c6b4 in
Engine_open (name=0x2e7b4 "videnc", attrs=0xbefffb24, ec=0xbefffb20) at
Engine.c:544.Please can any one help me on this.
