<br>主题：如何让Debug Multithreaded编译通过的程序改为Debug Multithreaded Dll编译能通过？
<br>内容：我用MFC建立了一个工程，要使用一个静态库avi.lib，可是这个静态库avi.lib，在Debug Multithreaded环境下能编译通过，而MFC建立的工程都是Debug Multithreaded Dll。请教各位高手，能不能通过更改某些设置，让静态库avi.lib用Debug Multithreaded Dll也能编译通过？或者mfc的工程能用Debug Multithreaded 编译通过？<BR><BR>以下是用Debug Multithreaded Dll编译的时候产生的问题：<BR>Linking...<BR>LIBCMT.lib(lseek.obj) : error LNK2005: __lseek already defined in MSVCRTD.lib(MSVCRTD.dll)<BR>LIBCMT.lib(crt0.obj) : error LNK2005: _mainCRTStartup already defined in MSVCRTD.lib(crtexe.obj)<BR>LIBCMT.lib(winxfltr.obj) : error LNK2005: __XcptFilter already defined in MSVCRTD.lib(MSVCRTD.dll)<BR>LIBCMT.lib(crt0dat.obj) : error LNK2005: _exit already defined in MSVCRTD.lib(MSVCRTD.dll)<BR>LIBCMT.lib(crt0dat.obj) : error LNK2005: __exit already defined in MSVCRTD.lib(MSVCRTD.dll)<BR>LIBCMT.lib(crt0init.obj) : error LNK2005: ___xc_z already defined in MSVCRTD.lib(cinitexe.obj)<BR>LIBCMT.lib(crt0init.obj) : error LNK2005: ___xc_a already defined in MSVCRTD.lib(cinitexe.obj)<BR>LIBCMT.lib(crt0init.obj) : error LNK2005: ___xi_z already defined in MSVCRTD.lib(cinitexe.obj)<BR>LIBCMT.lib(crt0init.obj) : error LNK2005: ___xi_a already defined in MSVCRTD.lib(cinitexe.obj)<BR>LIBCMT.lib(lseek.obj) : warning LNK4006: __lseek already defined in MSVCRTD.lib(MSVCRTD.dll); second definition ignored<BR>LIBCMT.lib(crt0.obj) : warning LNK4006: _mainCRTStartup already defined in MSVCRTD.lib(crtexe.obj); second definition ignored<BR>LIBCMT.lib(winxfltr.obj) : warning LNK4006: __XcptFilter already defined in MSVCRTD.lib(MSVCRTD.dll); second definition ignored<BR>LIBCMT.lib(crt0dat.obj) : warning LNK4006: _exit already defined in MSVCRTD.lib(MSVCRTD.dll); second definition ignored<BR>LIBCMT.lib(crt0dat.obj) : warning LNK4006: __exit already defined in MSVCRTD.lib(MSVCRTD.dll); second definition ignored<BR>LIBCMT.lib(crt0init.obj) : warning LNK4006: ___xc_z already defined in MSVCRTD.lib(cinitexe.obj); second definition ignored<BR>LIBCMT.lib(crt0init.obj) : warning LNK4006: ___xc_a already defined in MSVCRTD.lib(cinitexe.obj); second definition ignored<BR>LIBCMT.lib(crt0init.obj) : warning LNK4006: ___xi_z already defined in MSVCRTD.lib(cinitexe.obj); second definition ignored<BR>LIBCMT.lib(crt0init.obj) : warning LNK4006: ___xi_a already defined in MSVCRTD.lib(cinitexe.obj); second definition ignored<BR>&nbsp;&nbsp; Creating library Debug/avidemo.lib and object Debug/avidemo.exp<BR>LINK : warning LNK4098: defaultlib &#34;MSVCRTD&#34; conflicts with use of other libs; use /NODEFAULTLIB:library<BR>LINK : warning LNK4098: defaultlib &#34;LIBCMT&#34; conflicts with use of other libs; use /NODEFAULTLIB:library<BR>LINK : warning LNK4098: defaultlib &#34;LIBC&#34; conflicts with use of other libs; use /NODEFAULTLIB:library<BR>Debug/avidemo.exe : fatal error LNK1169: one or more multiply defined symbols found<BR>Error executing link.exe.<BR>

<br>内容：我把mfc的工程改为Use MFC In a Static Library,Code Generation里面自动变成Debug Multithreaded 了。如果不改这个，直接用Debug Multithreaded ，编译通不过。<BR>这么做不知道对我的程序有什么影响。多谢这位朋友帮忙。<BR>2003-12-27 16:13:37
