我在dm6467的dvsdk_2_00_00_18上开发自己的库，库的位置在如下目录：dvsdk_2_00_00_18\codec_engine_2_21\examples\ti\sdo\ce\examples\codecs\track，现在有性能问题，想使用o3选项优化，package.bld设置如下：
/* * ======== package.bld ======== */
var Build = xdc.useModule('xdc.bld.BuildEnvironment');
var Pkg = xdc.useModule('xdc.bld.PackageContents');
/* when constructing a release, release everything */
Pkg.attrs.exportAll = true;
// Uncomment this to build debug binaries
Pkg.attrs.copts = "-o3";
/* * Create an array containing the files to include in this package. Note * that the extension is added by XDC, so it need not be explicitly specified. */ var SRCS = ["track_impl.c","track.c","tracking.c","AutoTrack.c","OverLapImage.c","MSR.c"];
for (var i = 0; i < Build.targets.length; i++) { var targ = Build.targets[i];
print("building for target " + targ.name + " ...");
/* * Add a library to this package and add the files described in * SRCS to the library. */ Pkg.addLibrary("lib/track", targ).addObjects(SRCS); } /* * @(#) ti.sdo.ce.examples.codecs.scale; 1, 0, 0,204; 7-25-2009 21:30:29; /db/atree/library/trees/ce/ce-n11x/src/ */
编译报错：
出现-O2 -O3两个优化选项。如果默认的话，是-O2。
请问有谁知道怎么回事吗？
