<p><span style='font-family:"Calibri","sans-serif"'>I’m stuck with

the part of the API that normally allow to call an external program (an exe

<p><span style='font-family:"Calibri","sans-serif"'>I mean the linker
can’t find the</span> <span style='font-family:"Calibri","sans-serif"'>“call”</span> <span
