[提问]关于dm6467开发的三个细节问题



1)在 xdcpaths.mak 中有: CGTARGET = gnu.targets.arm.GCArmv5T

   在 ExampleRoot中的Config.bld中有:var MVArm9 = xdc.useModule('gnu.targets.MVArm9');

   在 ExampleRoot中的User.bld中有:target:  "gnu.targets.arm.GCArmv5T",

   请问:gnu.targets.MVArm9 和 gnu.targets.arm.GCArmv5T 分别指的什么含义,他们有不同吗?

(2) shell脚本(XDC_INSTALL_DIR)/xs 中的注释内容有如下一段:

   #  This script is necessary on Unix hosts *only* because we need to control  

   #  the LD_LIBRARY_PATH environment variable to ensure that the proper dynamic

   #  libraries are found

   请问:Linux作为开发的host主机,是不是就用不到工具软件xs?

(3) app段程序的makefile有这样的代码:

    CONFIGURO = XDCPATH="$(XDC_PATH)" $(XDC_INSTALL_DIR)/xs xdc.tools.configuro

    $(CONFIGPKG) : $(CONFIGPKG).cfg

    $(CONFIGURO) -c $(CGTOOLS) -o $(CONFIGPKG) -t $(XDCTARGET) -p $(XDCPLATFORM) -b      $(CONFIG_BLD) $(CONFIGPKG).cfg

    请问: makefile中的连续等号  CONFIGURO = XDCPATH="$(...

    该如何理解,类似C语言吗
