we know in android source the external/ti-dsp/makefile :
dvsdk:
make -C $(DVSDK_INSTALL_DIR) dsplink_arm
make -C $(DVSDK_INSTALL_DIR) dsplink_dsp
make -C $(DVSDK_INSTALL_DIR) dsplink_gpp_genpackage
make -C $(DVSDK_INSTALL_DIR) dsplink_dsp_genpackage
make -C $(DVSDK_INSTALL_DIR) lpm
make -C $(DVSDK_INSTALL_DIR) cmem
make -C $(DVSDK_INSTALL_DIR) sdma
make -C $(DVSDK_INSTALL_DIR) ce
# make -C $(DVSDK_INSTALL_DIR) ce_examples
make -C $(DVSDK_INSTALL_DIR) codecs
make -C $(DVSDK_INSTALL_DIR) dmai
make -C $(DVSDK_INSTALL_DIR) c6accel
so i build make -C external/ti-dsp/ TARGET_PRODUCT=omap3evm OMAPES=5.x -j1 it success
but if i add make -C $(DVSDK_INSTALL_DIR) demos when it makes,errors comes:
