Hi
It's me again!! I've moved on from compiling via scons, sorting out the libOpenCL stub libs and running the examples. The inacantation shown in the documentation under Building for linux-> How to manually build the examples has some issues that I've been trying to find a solution for but I'm not so familiar with this type of command line compilation!
I'm building natively on an Odroid XU4 board, 32 bit, but following one of the examples under "To compile an OpenCL example for Linux 32bit" The following line produces:-
odroid@odroid:~/ComputeLibrary-17.12$ g++ examples/cl_convolution.cpp utils/Utils.cpp -I. -Iinclude -std=c++11 -larm_compute -larm_compute_core -lOpenCL -o cl_convolution -DARM_COMPUTE_CL/usr/bin/ld: cannot find -larm_compute/usr/bin/ld: cannot find -larm_compute_corecollect2: error: ld returned 1 exit statusI think this is because it's looking for the .so files that should be libarm_compute and libarm_compute_core not arm_.... ? Am I correct?I changed the two entries to -L libarm_compute and -L libarm_compute_core and it seems to remove the "cannot find" error and moves on to the next stage. I tried -llibarm_compute and -llibarm_compute_core but still causes a later "cant find" error after what looks like the compile stage. The "-L " before the libs seems to get the process further down the line. But we now get a host of what I think are linkage errors, possibly to do with the STUB files that are needed during a Scons build and the LD_LIBRARY_PATH that is needed when running the executable!I can get round these issues by editing a file in the ComputeLibrary-17.12/examples folder and running scons to compile the examples, that ignores any that haven't been changed but takes a fair bit of time while during the process! I'd like to be able to compile just the file I'm working on!!
Can anyone help before I short circuit my brain??I'm trying to add a text file with the compile output, I haven't done this before so I'm not sure I'm following the correct protocol, so apologies if I'm wrong!RegardsDaveCommand line was:-g++ examples/cl_convolution.cpp utils/Utils.cpp -v -I. -Iinclude -std=c++11 -L libarm_compute -L arm_compute_core -L OpenCL -o cl_convolution -DARM_COMPUTE_CL &> compile.txtUsing built-in specs.

Well, not having had any suggestions after the original post, it looks as though I'm on my own as an attempted early adopter of the Compute Library!!
I decided to see if I could adapt the Scons process to generate a compilation path for my own code! So I went to scons.org/doc/2.4.1/HTML/scons-user.htm and downloaded the user guide relevant to my installed version of SCons. I found this quite a good intro into the philosophy of how SCons works and why it was recompiling everything when I changed debug settings etc. I then embarked on modifying the SConstruct file in the ComputeLibrary-17.12 directory. I simply searched for the 'examples' BoolVariable and created a new similar one to source a new directory 'MyProg'. There is also an SConscript file in this folder but that doesn't need to be touched!
BoolVariable("MyProgs", "Build my programs", True),
Towards the end of the file the 'examples' BoolVariable is used top set up the source and build paths:
if env['examples'] and env['os'] != 'bare_metal': SConscript('./examples/SConscript', variant_dir='#build/%s/examples' % env['build_dir'], duplicate=0)
I created a new insertion for 'MyProgs'
if env['MyProgs'] and env['os'] != 'bare_metal': SConscript('./MyProgs/SConscript', variant_dir='#build/%s/MyProgs' % env['build_dir'], duplicate=0)
As I am doing some initial development/investigative work and building natively, I also changed some of the default values in the Sconstruct to reflect the build I would be using for some time yet!
A further step is needed! In the examples directory along with the source code there is a further Sconscript file which is called by the upper level files, I copied this into the MyProgs folder. I then edited that new file and changed all instances of 'examples' to 'MyProgs'.
Bingo! I can now compile files in my own compilation folder without recompiling the examples everytime I change one of the compilation directives.
Ill try attaching (fingers crossed!) the before "OriginalSConstruct" and after "SConstruct" if anyone wants to compare my changes between the files.

I posted an article that may help you a bit.. It does demonstrate how to modify an application to add your own code. In my case the added code is for Streamline annotation, but the scons changes are attached to the end of the article.
