build error in "Fast memcpy with SPDK and Intel® I/OAT DMA Engine"


I've followed the steps in Article "Fast memcpy with SPDK and Intel® I/OAT DMA Engine" but meet an error in the last make command:


  • mkdir <build-dir>
  • cd <build-dir>
  • cmake -DCMAKE_BUILD_TYPE=Release $OLDPWD
  • make




root@ubuntu:/opt/ex4/build# cmake -DCMAKE_BUILD_TYPE=Release $OLDPWD

Is it caused by the latest spdk tools which change the function spdk_malloc syntax?  
I wonder if there is any walk-around that I could do?
Best Regards,
Martin Wang
