编译例程主要有4个步骤，1、编译codec；2、编译extensions目录；3、编译server；4、编译apps 首先进入codec_engine范例目录 cd /root/dvsdk_2_00_00_22/codec_engine_2_23_01/examples 1、编辑user.bld 使能“DSP”，其他的都是false，并指定编译器目录，将除DM6467以外的平台都注释掉 var buildTable = {

    if (t.name == "GCArmv5T") {

    }
}
2、编辑xdcpath.mak文件 DEVICES  := DM6467
PROGRAMS := DSP_SERVER //表示现在要编译DSP server

接下来指定各工具的安装目录 CE_INSTALL_DIR      := /root/dvsdk_2_00_00_22/codec_engine_2_23_01
XDC_INSTALL_DIR       := /root/dvsdk_2_00_00_22/xdctools_3_10_05_61
BIOS_INSTALL_DIR      := /root/dvsdk_2_00_00_22/bios_5_33_03


# no need to specify the installation directories below if your CE installation
# has cetools/ directory on top
USE_CETOOLS_IF_EXISTS := 1
XDAIS_INSTALL_DIR     := /root/dvsdk_2_00_00_22/xdais_6_23
DSPLINK_INSTALL_DIR   := /root/dvsdk_2_00_00_22/dsplink-1_61_03-prebuilt
CMEM_INSTALL_DIR      := /root/dvsdk_2_00_00_22/linuxutils_2_23_01

# (Mandatory) specify correct compiler paths and names for the architectures
# you'll be building for:


# compiler path and name for Montavista Arm 9 toolchain. NOTE: make sure the
# directory you specify has a "bin" subdirectory
CGTOOLS_V5T = /opt/mv_pro_5.0.0/montavista/pro/devkit/arm/v5t_le
CC_V5T = bin/arm_v5t_le-gcc
CGTARGET = gnu.targets.arm.GCArmv5T


# compiler path and name for TI C64x toolchain. NOTE: make sure the
# directory you specify has a "bin" subdirectory
CGTOOLS_C64P = /root/dvsdk_2_00_00_22/cg6x_6_0_23
CC_C64P      = bin/cl6x


# compiler path and name for TI C674 toolchain. NOTE: make sure the
# directory you specify has a "bin" subdirectory
CGTOOLS_C674 = /root/dvsdk_2_00_00_22/cg6x_6_0_23
CC_C674      = bin/cl6x
3、进入/root/dvsdk_2_00_00_22/codec_engine_2_23_01/examples/ti/sdo/ce/examples/codecs 执行 gmake clean 执行gmake 4、进入/root/dvsdk_2_00_00_22/codec_engine_2_23_01/examples/ti/sdo/ce/examples/extensions 执行 gmake clean 执行gmake 5、进入/root/dvsdk_2_00_00_22/codec_engine_2_23_01/examples/ti/sdo/ce/examples/servers 执行 gmake clean 执行gmake 6、经过以上步骤 生成 video_copy.x64P 接下来改变一下配置文件编译Arm端应用程序 7、编辑user.bld 将arm设置为true，其他的地方设置为false，并设置编译器     "Arm":    [{doBuild: true, // standard build for Linux
                target:  "gnu.targets.arm.GCArmv5T",


                // Arm tools. NOTE: make sure the directory you specify has a "bin" subdirectory
                cgtoolsRootDir: "/opt/mv_pro_5.0.0/montavista/pro/devkit/arm/v5t_le",


// specify custom toolchain options
for (var i = 0; i < Build.targets.length; i++) {
    var t = targets[i];


    if (t.name == "GCArmv5T") {
t.LONGNAME = "bin/arm_v5t_le-gcc";
    }
}

8、 编辑xdcpath.mak文件 PROGRAMS := APP_CLIENT //表示现在要编译arm端程序
9、进入/root/dvsdk_2_00_00_22/codec_engine_2_23_01/examples/ti/sdo/ce/examples/apps/video_copy/dualcpu 执行 gmake clean和 gmake 生成app.out可执行文件。
