请问Unresolved symbol错误该怎么解决？

[tr] 请教大神一下，我将SYS/BIOS的Demo例程中的MMCSD_FATFS与LCD_TOUCH整合在了一个工程中。当我将MMCSD_FATFS的程序移到LCD_TOUCH的程序中时会出现以下错误。

#10234-D  unresolved symbols remain        LCD_TOUCH                         C/C++ Problem

我根据网上提示添加了相关的头文件和库文件，错误中中指出的bios_psp_mmcsd.ae674，bios_psp_blkmedia.ae674等我都添加了，但是错误还在，不知道如何解决。


当我将LCD_TOUCH程序移到MMCSD_FATFS程序中时，通过编译会产生如下的错误：
Description        Resource        Path        Location        Type

请大神帮忙指点一下。
