Linking to c.obj in Visual Studio 2010

[yzhao0527]

I initiated this question in a separated post : https://groups.google.com/d/topic/personal-kdbplus/sGTaB0rVRjk/discussion

but got really frustrated with Visual Studio 2010. My goal is to write a tool like the Studio for KDB+ so others can use it without dealing with c.dll and setting environmental variables.

My code is very simple:

//--------------------------BEGIN------------------------------------------------
#define KXVER 3
#include "k.h"

int main(int argc, char *argv[]) {
    int handle;
    handle=khpu("localhost",5000,"username:password");

    return 0;
}
//--------------------------END------------------------------------------------

I did the following to build the program in Visual studio 2010.

1. right click solutions -> properties -> Configuration Properties -> VC++ Directories : I modified Include Directory and Library Directory
2. right click solutions -> properties -> Configuration Properties -> Linker -> Input: I added c.obj to Additional Dependencies.

However, the code fails with the following Error Message:

I don't know what's wrong. If I use c.lib instead of c.obj, the code got compiled successfully, but it would require c.dll to run. Some one kindly suggested me to include /NODEFAULTLIB:MSVCRTD as the linker option, but this only caused other trouble.

I would be greatly appreciative if you can help me out ...

... and ... thanks for your time reading my post, even if you couldn't offer help 🙂
