Caffe(OpenCL) Error: ordered comparison between pointer and zero ('int32_t *' (aka 'int *') and 'int')

[rajhlinux]

Issue summary

I get the following error:

/home/user/caffe/src/caffe/backend/device.cpp:280:50: error: ordered comparison between pointer and zero ('int32_t *' (aka 'int *') and 'int')
  if (*lock_id < buffer_flags_.size() && lock_id > 0) {

Here is the Full Error displayed from terminal:
https://pastebin.com/VWFXNumJ

Here is the Cmake Error Log:
https://pastebin.com/fEeDFcBX

Steps to produce:
(Note: I am not building with python, do not need it since I am trying to build Caffe so that it can be used by another project called "OpenPose", also I program in C/C++)

How I config and generate with cmake:

cmake \
-D ViennaCL_INCLUDE_DIR=../ViennaCL-1.7.1 \
-D OPENCL_INCLUDE_DIRS=../ViennaCL-1.7.1/CL/ \
-D OPENCL_LIBRARIES=/usr/local/lib/libMesaOpenCL.so.1 \
-D CMAKE_BUILD_TYPE=Release \
-D CPU_ONLY=false \
-D BUILD_python=False \
-D BUILD_python_layer=False \
-D USE_OPENCL=ON \
-D BLAS=open ..

Here is the cmake config and generate info:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Alright, was able to fix this problem by doing the following below:

Access to edit the file at line 280:
/home/user/caffe/src/caffe/backend/device.cpp
Change and edit:
if (*lock_id < buffer_flags_.size() && lock_id > 0)
To the correct code:
if (*lock_id < buffer_flags_.size() && lock_id != nullptr)

Save and exit.
