一个编译警告问题

[liuwencoding]

在release 版本，而且选择的是Use MFC in a Static Library，编译会出现如下的警告：
LINK : warning LNK4089: all references to "SHELL32.dll" discarded by /OPT:REF
请问这个警告是什么意思，为什么会这样？
而我该成debug版本就没有出现这个警告，或者在release版本，选择 use MFC in a shared DLL
也不会出现警告！

Linker Tools Warning LNK4089

all references to "dynamic-link library" discarded by /OPT:REF

The linker discarded all packaged functions that referenced exports in dynamic-link library. As a result, dynamic-link library is not needed for execution of the image.

You may want to consider removing references to dynamic-link library to speed up the build.

Other occurrences of this warning can occur if an unused function in your code references a .dll export that the linker has discarded. Use /VERBOSE to see which of your functions the linker is discarding and then remove them from your code.

优化链接的吧。。无妨

是个警告.编译选项设置一下就行了.上面不是都告诉你怎么做了?discarded by /OPT:REF

to lixiaosan(小三) ：
"Use /VERBOSE to see which of your functions the linker is discarding and then remove them from your code."
请问怎么用这个命令？应该加在那个编译选项内？

应该是手工拷到工程设置的Link页最下面吧

这个不用管它，因为你没有用到这个动态链接库，链接的时候就忽略掉，很正常。
