_malloc already defined in LIBC.lib(malloc.obj)
。。。。。。。。。。。。。。。。。。。。。。。

貌似下面象_molloc这样的都重名了，换个名字试下。。。

[hoya5121]

也不说你是什么编译器,做什么程序时候出的问题
大嘎应该是你的库目录设置的问题把

[gfxiang]

工程设置有问题

[oo]

工程设置有问题
LIBC.lib和LIBCD.lib里的东东一样的，就是后一个是debug版

[iu_81]

去掉一个lib

[hilary0810]

同时连接了debug,release库，工程属性

[SwordMan2001]

[星羽]

setting/Link的Ignore libraries 里把

libc.lib Ignore 看看

[raining_peidx]

hoya5121说的是，下次一定注意！
最后问题是这样解决的：在主工程下，setting->link->input,在Ignore libraries下添加libcd.lib,msvcrtd.lib,mfc42d.lib。
