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

[Wang__Martin]

Hi,

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

Makefile:83: recipe for target 'all' failed

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?
