Hi everyone<div><br></div><div>I am trying to compile a C++ program which uses libvirt to connect to an ESXi host. I got the code running if I wrote it in C, directly in the hellolibvirt.c example. However, I am now trying to compile that code in a C++ file which is not inside the example directory.</div>
<div><br></div><div>I tried to compile with the following command:</div><div><div>g++ -g -D debug=1 -c -llibvirt ESXWrapper.cpp</div><div>g++ -g -D debug=1 -o ESXWrapper ESXWrapper.o</div></div><div><br></div><div>The first line passes and creates ESXWrapper.o file. But when I run the second line, it gives me the following error:</div>
