【求助】这个 MDK5 编译警告如何处理

之前用的是MDK4,编译这个工程没有警告信息;
迁移到MDK5之后就多出来了这么一个警告信息,但是程序是可以正常运行的,就是不知道如何解决这个警告,或者是屏蔽这个警告???

查了一下手册,警告代码对应的信息如下:
Disabling merging for section <sec> from object <obj>, non R_ARM_ABS32 relocation from section <srcsec> from object <srcobj>

我记得之前碰到过, 原因是用了最新的库, 库里有个预编译的条件, 低版本的不能用, 不知道你的情况是否一样

一是用回旧的库
二是更新编译器版本

我当时选择了二

因为是编译之后的链接警告,直接在 linker配置下屏蔽该代码即可
