You need to make at least one instance of OBConversion, so that the
plugin files are loaded. (I realise that this is not very elegant and
we should find a better way.)
So with Visual Studio 2008, the trunk code and the CMake default build
(making openbabel2.dll and several plugin .obf files) and the short
exe below:
without an OBConversion object, only genalias is listed (it is the
only Op in openababel2.dll) and pOp is NULL;
with the line uncommented, all the ops are listed and pOp is not NULL.
Is there a reason for you to include the format files in a single DLL?
Would it not be easier to use the standard build?
Chris
#include <openbabel/op.h>
#include <openbabel/obconversion.h>
using namespace OpenBabel;
int main(int argc,char **argv)
{
// OBConversion dummy;
OBPlugin::List( "Ops" );
OBOp* pOp = OBOp::FindType("gen3D");
std::cout << "gen3D is at " << pOp;
return 0;
}
