本人在vc++6.0上编译一个工程时出现了如下错误信息:
rom_maplist.c
csp_maplist.c
Linking...
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs; use /NODEFAULTLIB:library
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
demo___Win32_Debug/demo.cgi : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.

demo.cgi - 1 error(s), 0 warning(s)
 不知如何解错，请老师们指点迷津，谢谢！

代码呢

csp_maplist.c的代码：

c语言只有main这一个入口函数  你咋弄出个 int cgimain()   ？？？

这是一个cgi程序，入口是cgimain()

单个程序编译都通过了，但是一加链接库就出现下面的错误：
rom_maplist.c
csp_maplist.c
Linking...
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs; use /NODEFAULTLIB:library
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
demo___Win32_Debug/demo.cgi : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.

demo.cgi - 1 error(s), 0 warning(s)

是不是链接库之间有冲突。我是按文档要求
“添加eyBuildLib库的搜索路径，方法是：打开Project Æ Setting ÆLink 选项卡，
在分类（Category）下拉框中选择General，并在Object/library modules:输入框最后（项与项之间用空格分隔）添加项$(EYBUILD_BASE)/lib/eybuild.lib”
做的但编译时出现错误。

cgi的没玩过  不知道和普通的一不一样

普通的main程序 则是 包含头文件和 引入链接库（lib) 同时具备 否则无法编译

这是一个cgi程序，入口是cgimain()
------ 没有这说法，而且所谓“入口函数”也只是C/C++中的一个“概念”而已。
