x264之c64x+平台移植（二）：arm端应用程序编译

参考codec server的html文档写app.cfg:

var osalGlobal = xdc.useModule('ti.sdo.ce.osal.Global');

osalGlobal.runtimeEnv = osalGlobal.LINUX;

xdc.useModule('ti.sdo.xdcruntime.linux.Settings');

xdc.useModule('ti.sdo.ce.ipc.dsplink.Ipc');

xdc.useModule('ti.sdo.ce.ipc.dsplink.Processor');//注意这行，漏掉的话会链接失败。

var Engine = xdc.useModule('ti.sdo.ce.Engine');

var myEngine = Engine.createFromServer(

"x264server", // Engine name (as referred to in the C app)

"bin/x264server.xe64P", // path to server exe, relative to its package dir

"xmu.x264server" // full server package name

);

var SCPY = xdc.useModule('ti.sdo.fc.scpy.SCPY');

var SDMA = xdc.useModule('ti.sdo.linuxutils.sdma.SDMA');

app.bld:

var GCArmv5T = xdc.useModule('gnu.targets.arm.GCArmv5T');

GCArmv5T.LONGNAME = 'bin/arm-none-linux-gnueabi-gcc';

GCArmv5T.platform = "ti.platforms.evm3530";

//GCArmv5T.rootDir = "C:\\Program Files\\CodeSourcery\\Sourcery G++ Lite";

GCArmv5T.rootDir = "/media/work/sdk/Sourcery_G++_Lite";

Build.targets = [

];

运行XDCPATH="/media/work/sdk/codec_engine_3_21_00_19/packages;/media/work/sdk/codec_engine_3_21_00_19/cetools/packages;/media/work/sdk/codec_engine_3_21_00_19/syslink_2_00_02_80/packages;/media/develop/git/x264dsp" "/media/work/sdk/codec_engine_3_21_00_19/xdctools_3_22_02_27/xs"
xdc.tools.configuro -o cfg_tmp -t gnu.targets.arm.GCArmv5T -p ti.platforms.evm3530 -b app.bld app.cfg

生成codec server的配置

删除linker.cmd的后面SECTIONS开始至文件尾部分，注意不能用-T linker.cmd编译，否则会莫名其妙地链接失败^_^

最后编译app对应的代码：

/opt/CodeSourcery/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc -o x264app v4l2_x264.o cfg_tmp/linker.cmd -lpthread -ldl -lrt

注意：

1、 linker.cmd与输入文件的顺序，并且不能加"-T"

2、链接时要加上-ldl -lrt。
