compile vmci program

I'm trying to compile the vmware vmci example program. The program is divided into two parts

a) kernel module b) example datagram program

When i compiled that datagram program i get these errors :

gcc -I headers_path datagramApp.c
/tmp/cc6KkQ4a.o: In function开发者_StackOverflow中文版 `main':

You need to link with a (shared) object to get the userland interface of VMCI

AFAICT this is a propriatary API from Vmware(?) that you should install [1]

The typical compile line would then look more like:

gcc -I <headers_path> datagramApp.c -lvmci

Notes

• replace header_path with something like (depending on where the module was built)
  • /usr/src/linux/include
  • /opt/vmware/include
• -lvmci would suggest the availability of a libvmci.so in your library path (remember to sudo ldconfig -a, optionally include -L/path/to/libs in order to make gcc/ld find)them

[1] perhaps as part of the Custom Installation of VMware Tools?
