I'm trying to compile the code below in Visual Studio, and I'm getting this warning about machine type. Is it related to the fatal error?
Is the fatal error referring to the library?
 
C:\Program Files\Csound6_x64\lib\csound64.lib : warning LNK4272: library machine type 'x64' conflicts with target machine type 'x86'
1>C:\jana\csound\projects\csound_api_test\Debug\csound_api_test.exe : fatal error LNK1120: 140 unresolved externals
1>Done building project "csound_api_test.vcxproj" -- FAILED.

#include "csound.hpp"

int main(int argc, const char** argv)
{
	Csound* cs = new Csound();
int result = cs->Compile(argc, argv);
	if (result == 0)
	{
		result = cs->Perform();
	}
	return (result >= 0 ? 0 : result);

}

I think you just need to select to build an x64 project configuration in Visual Studio. It can do both, but Csound is a 64 bit library, so it won't work with 32 bit programs.

Just get rid of the 32 bit configurations, you won't need those.
