原来IAR5.3的工程，移至6.3下，编译，0error，0warning。 链接时出现问题，e183：Static overlay map generation(-xo) is not supported forMSP430 processor,,,解决办法就是进去工程属性Linker -》List uncheck "Static overlay map" 问题就处理了。但是后面又出现新的问题，当然都是builder，0errors，0warning。链接时出现 e46:Undefined external "__iar_HWMUL" referred in adc10_a ,本人看到6.3的inc/HwMulSetup.h 文件有定义，把此文件加入工程，问题依然存在，求助论坛网友，给我提供解决思路。

Error[e46]: Undefined external "__iar_HWMUL" ...
EW targets: 430
EW component: Linker
Keywords: XLINK
Last update: March 30, 2015
Problem
Trying to build an established project using version 6.20 (or later), linking fails with the message
Error[e46]: Undefined external "__iar_HWMUL" ...
Suggested solution
Use the default linker xcl-file for the installation you are using.
Background
The symbol __iar_HWMUL has been introduced with 6.20.
Using lnk430f149.xcl as example, there are new lines as below:
// -----------------------------------------------
// Hardware multiplier location
//
-D__iar_HWMUL=130
Note
In general, there are good reason to use only matching versions (e.g., header files, xcl-files, libraries, tools from the same release).
