发帖数: 731 | 1 我现在使用的是oracle8i，WINDOWS 2000。想用PRO*C连接ORACLE数据库。PRO*C程序预编
译通过，但是联编出现问题。
在VC中编译出错，如下：
Linking...
proj1Dlg.obj : error LNK2001: unresolved external symbol "void __cdecl
sqlcxt(void * *,unsigned long *,struct sqlexd *,struct sqlcxp const *)"
(?sqlcxt@@YAXPAPAXPAKPAUsqlexd@@PBUsqlcxp@@@Z)
Debug/proj1.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
proj1.exe - 2 error(s), 0 warning(s)
不知问题出在那，请指教 |

发帖数: 1258 | 2 这几句是我刚才写的，修改了一下
char* fileName="abcdefg";
int len=strlen(fileName);
LinearSuffixSort(fileName,len);
还是不行,VC 6下，compile通过(no error)，build的时候
=======================
error LNK2001: unresolved external symbol "int * __cdecl LinearSuffixSort(ch
ar * &,int &)" (?LinearSuffixSort@@YAPAHAAPADAAH@Z)
fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
=======================
谢谢

发帖数: 270 | 5 要被继承的类(DllObject)定义在Project A, 用DLL导出. 而子类(MyClass)定义在
Project B.
在Project A中, 我定义了宏MYDLL_BUILD.
// Config_Project_A.h
#if !defined(MYDLL_BUILD)
# pragma comment(lib, "myDll.lib")
#endif
#if defined(MYDLL_BUILD)
# define MYDLL_API __declspec(dllexport)

这个倒底是怎么回事？ |
