链接的问题

[tlovexyj]

在使用stlport（需要多线程支持），然后就会看到
编译器报以下的警告：
LINK : warning LNK4098: defaultlib "LIBCMTD" conflicts with use of other libs; use /NODEFAULTLIB:library

另外，在此情况下，使用zlib，就会报如_exit、_free等已经在xxx.obj中定义了，然后链接错误:~~~(

请各位大侠帮帮忙，讲解一下！！！如果避免或解决。

不大了解,帮你UP

LINK : warning LNK4098: defaultlib "LIBCMTD" conflicts with use of other libs; use /NODEFAULTLIB:library
默认的连接库和其他已经使用的连接库有冲突
你换掉看看，
在说，是警告，也不是错误

谢谢大家^_^

抱歉，我太不仔细了，在project settings的link页ignore library中加入libc.lib, msvcrt.lib后，编译器又报如下的警告：

LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
LINK : warning LNK4049: locally defined symbol "_fclose" imported
LINK : warning LNK4049: locally defined symbol "_fread" imported
LINK : warning LNK4049: locally defined symbol "_fopen" imported
LINK : warning LNK4049: locally defined symbol "_strncpy" imported
LINK : warning LNK4049: locally defined symbol "__setmbcp" imported

我说漏了一点
有时MFC和其他库如stlport一起用，因为都用了多线程，就会报以下的错误：

Linking...

这个时候怎么办？

在project settings的link页ignore library中应该有
libc.lib, libcmt.lib, msvcrt.lib, libcd.lib, msvcrtd.lib

不熟悉,帮你UP

不懂
Good Luck!

肯定是你设定的链接库不对，例如是几个Project，有的设定未Not use MFC，有的是Using MFC in Share DLL或者是Static Dll等。只有这样才可能导致这个问题。

在project settings的link页ignore library中加入
libc.lib, msvcrt.lib
