Hi
I am new to using the openbabel API. I have an existing C++ program in
MSVC2008 that i would like to use some of the functions in openbabel.
I followed the instructions on the website and built the windows-vc2008 and
then tried to add the sample code:
#include <iostream>
#include <openbabel/obconversion.h>
using namespace std;
int main(int argc,char **argv)
{
if(argc<3)
{
cout << "Usage: ProgrameName InputFileName OutputFileName";
return 1;
}
ifstream ifs(argv[1]);
if(!ifs)
{
cout << "Cannot open input file";
return 1;
}
ofstream ofs(argv[2]);
if(!ofs)
{
cout << "Cannot open output file";
return 1;
}
OpenBabel::OBConversion conv(&ifs, &ofs);
if(!conv.SetInAndOutFormats("CML","MOL"))
{
cout << "Formats not available" << "InputFileName";
return 1;
}
int n = conv.Convert();
cout << n << " molecules converted";
return 0;
}
It finished compiling but i had the following linker issues:
1>obconversion.obj : error LNK2019: unresolved external symbol "public: int
__thiscall OpenBabel::OBFormat::RegisterFormat(char const *,char const *)"
(?RegisterFormat@OBFormat@OpenBabel@@QAEHPBD0@Z) referenced in function
"public: static int __cdecl OpenBabel::OBConversion::RegisterFormat(char
const *,class OpenBabel::OBFormat *,char const *)"
(?RegisterFormat@OBConversion@OpenBabel@@SAHPBDPAVOBFormat@2@0@Z)
1>obconversion.obj : error LNK2019: unresolved external symbol "public:
static class OpenBabel::OBPlugin * __cdecl
OpenBabel::OBPlugin::GetPlugin(char const *,char const *)"
(?GetPlugin@OBPlugin@OpenBabel@@SAPAV12@PBD0@Z) referenced in function
"protected: static int __cdecl
OpenBabel::OBConversion::LoadFormatFiles(void)"
(?LoadFormatFiles@OBConversion@OpenBabel@@KAHXZ)
...and more
I was wondering where are the libraries that i should be linking to? Are
they in the windows-vc2008 libs.
Thanks!
