哪位 老大 帮我看下这个是怎么回事-新问题有程序
c:\program files\microsoft visual studio\myprojects\ftp\1.cpp(35) : error C2065: 'sprintf' : undeclared identifier
c:\program files\microsoft visual studio\myprojects\ftp\1.cpp(50) : error C2065: 'printf' : undeclared identifier
我用libnids 和 winpcap 开发包做的 安装没有问题
还有 我编译libinds 里面自带的程序事例 也有上面的问题
新问题又出来了
1.obj : error LNK2001: unresolved external symbol "void __cdecl nids_run(void)" (?nids_run@@YAXXZ)
1.obj : error LNK2001: unresolved external symbol "void __cdecl nids_register_tcp(void *)" (?nids_register_tcp@@YAXPAX@Z)
1.obj : error LNK2001: unresolved external symbol "char * nids_errbuf" (?nids_errbuf@@3PADA)
1.obj : error LNK2001: unresolved external symbol "int __cdecl nids_init(void)" (?nids_init@@YAHXZ)
Debug/1.exe : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.
build不是链接库的问题 我都连好了的 估计是版本问提 我没libnids -1.19在windows的版本 哪未有的给我传个好不
我把程序贴上来 希望哪位高手帮我解决下 谢谢了 需要用到libnids1.19-win32 和 winpcap3.0 以上好象 要在libnids1.17-win32 和 winpcap3.0 我的QQ156282546 再次谢谢各位了
