Have you tried to declare C linkage like this:
extern "C" { #include <smi.h> }

Hi, I'm a newbie using libsmi and I have a little problem.
I try to use the libsmi library in a c++ program (using MSVC++ 6.0) but I obtain the following link error:
SMISurfer.obj : error LNK2001: unresolved external symbol "struct SmiModule
- __cdecl smiGetModule(char const *)"
(?smiGetModule@@YAPAUSmiModule@@PBD@Z) SMISurfer.obj : error LNK2001: unresolved external symbol "int __cdecl smiInit(char const *)" (?smiInit@@YAHPBD@Z) Debug/SnmpExtensionAgent.dll : fatal error LNK1120: 2 unresolved externals Error executing link.exe.
I can use the library in a little C program (win32 console aplication) without problems, but when I try to use the library in C++ (win32 dll project), MSVC++ is unable to link the library.
This is an example of my code:
// Simple method for open .mib file
BOOL SMISurfer::openMib(char *filename) { SmiModule *module;
smiInit(NULL); if ((module = smiGetModule(filename)) == NULL) return FALSE; else return TRUE; }
I include the smi.lib in the project settings.
Thanks.
