MCFW API DM814x

Hello all,

I'm starting with the DVR and have simple question. I can not use the API, I have problems with the includes.
My project is as follows:

# include <mcfw/interfaces/ti_vcap.h>
# include <mcfw/interfaces/common_def/ti_vcap_common_def.h>
# include <mcfw/interfaces/ti_vdis.h>
# include <mcfw/interfaces/ti_vdis_timings.h>
# include <mcfw/interfaces/common_def/ti_vdis_common_def.h>
# include <mcfw/interfaces/ti_venc.h>
# include <mcfw/interfaces/ti_vdec.h>
# include <mcfw/interfaces/ti_vsys.h>
# include <mcfw/interfaces/ti_media_std.h>
# include <mcfw/interfaces/ti_media_error_def.h>
# include <mcfw/interfaces/ti_media_common_def.h>
# include <mcfw/interfaces/common_def/ti_vsys_common_def.h>
# include <mcfw/interfaces/ti_vgrpx.h>
# include <mcfw/interfaces/common_def/ti_vgrpx_common_def.h>

But generates compile error when using some method:
eg: undefined reference to `Vcap_params_init '

Is there any lib that should be included in the project? Do I need anything else to use the API? Help, I'm lost!

Sorry my bad english.

Carol

    Are you getting compile time or link time errors > Is your build a make based build ? If you are getting link errors you have to link with the MCFW libs :

     $(LIB_DIR)/dvr_rdk_mcfw_api.a

     $(LIB_DIR)/dvr_rdk_link_api.a

    $(LIB_DIR)/dvr_rdk_common_utils.a

    $(LIB_DIR)/dvr_rdk_osa.a

    $(SYSLINK_LIBS)

    $(linuxdevkit_PATH)/usr/lib/libasound.so.2 -- If using audio

    $(rpe_PATH)/lib/lib/a8/debug/rpe.av5T - If using RPE.

    Hello Badri

    Thank you for reply.

    I'm getting link errors. I linked the LIBS and I can not use the API.

    I did not find the LIB $(LIB_DIR)/dvr_rdk_common_utils.a in the in my LIB_DIR.

    the makefile of my project was generated by eclipse. Is possible to have errors in my makefile?

    Message BUILD CONSOLE:

    **** Build of configuration Debug for project test_arm ****

    make all
    Building target: test_arm
    Invoking: Cross GCC Linker
    arm-none-linux-gnueabi-gcc -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_mcfw_api.a -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_link_api.a -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_osa.a -o "test_arm"  ./hello.o

    /root/workspace/test_arm/Debug/../hello.c:21: undefined reference to `Vcap_params_init'
    collect2: ld returned 1 exit status
    make: *** [test_arm] Error 1

    Thank you again Bradi!

    Is the link order generated by eclipse:

    arm-none-linux-gnueabi-gcc -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_mcfw_api.a -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_link_api.a -L/hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_osa.a -o "test_arm"  ./hello.o   

     

    My understanding is link order should be

    arm-none-linux-gnueabi-gcc  -o "test_arm"  ./hello.o    /hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_mcfw_api.a /hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_link_api.a /hdd2/DM810x-DVR-RDK/dvr_rdk/lib/ti810x-evm/dvr_rdk_osa.a

    based on library dependency

    Thank for your help Bradi.

    I can compiler my application. I did the makefile:

    CC = /opt/arm/arm-2009q1/bin/arm-none-linux-gnueabi-gcc

    INCLUDE = -I/dir/dvr_rdk
    LIB1 = -lpthread
    LIBS = /dir/dvr_rdk_mcfw_api.a  /dir/dvr_rdk_link_api.a  /dir/dvr_rdk_osa.a  /dir/syslink.a_release /dir/libasound.so.2

    CFLAGS = $(INCLUDE)

    all: test.arm
        $(CC) $(LIB1) -o test.arm test.o $(LIBS)

    test.arm: test.o

    test.o: test.c
        $(CC) $(CFLAGS) -c -o test.o test.c

    clean:
        rm *.o
