C66 DSP programming with OpenCL compile errors

[jomoengineer]

I'm attempting to go through the "C66 DSP programming with OpenCL" examples that are listed under Cloud9 AI->c66->README.md but I am running into compile errors when doing. I've gone through the Introduction_to_OpenCL_slides.pdf listed in the README and copied the examples to my home folder, but I am seeing the following errors for some of the examples.

Ex:
`cp -r /usr/share/ti/examples/opencl .

make`

I was able to get passed the SDL errors by installing SDL 1.2 (would have preferred SDL2), but the RTOS one I can not find info on.

===============  mandelbrot  =================

Compiling main.cpp

main.cpp:30:21: fatal error: SDL/SDL.h: No such file or directory

#include <SDL/SDL.h>

^

compilation terminated.

../make.inc:238: recipe for target 'main.o' failed

make[1]: *** [main.o] Error 1

===============  simple  =======

Installing SDL 1.2 as follows resolves this:
sudo apt-get install libsdl1.2-dev

This one I do not know.

===============  mandelbrot  =================

Compiling main.cpp

===============  simple  =================

===============  matmpy  =================

===============  sgemm  =================

/usr/bin/ld: libcblas_atlas_arm/libcblas.a(cblas_errprn.o): relocation R_ARM_THM_MOVW_ABS_NC against `stderr' can not be used when making a shared object; recompile with -fPIC

libcblas_atlas_arm/libcblas.a: error adding symbols: Bad value

collect2: error: ld returned 1 exit status

Makefile:16: recipe for target 'sgemm' failed

make[1]: *** [sgemm] Error 1

Also, I am not sure what to set PSDK_RTOS to to resolve these issues.

===============  persistent_kernel_timeout  =================

../make.inc:205: *** Environment variable PSDK_RTOS is not defined; set PSDK_RTOS to point at the target RTOS PSDK for automatic configuration or set  XDC_DIR to the corresponding package directories.  Stop.

===============  persistent_task_concurrent  =================

../make.inc:205: *** Environment variable PSDK_RTOS is not defined; set PSDK_RTOS to point at the target RTOS PSDK for automatic configuration or set  XDC_DIR to the corresponding package directories.  Stop.

===============  persistent_messageq_concurrent  =================

../../make.inc:205: *** Environment variable PSDK_RTOS is not defined; set PSDK_RTOS to point at the target RTOS PSDK for automatic configuration or set  XDC_DIR to the corresponding package directories.  Stop.

Makefile:5: recipe for target 'persistent_messageq_concurrent' failed

make[1]: *** [persistent_messageq_concurrent] Error 2

===============  persistent_clock_concurrent  =================

../make.inc:205: *** Environment variable PSDK_RTOS is not defined; set PSDK_RTOS to point at the target RTOS PSDK for automatic configuration or set  XDC_DIR to the corresponding package directories.  Stop.

Hello @jomoengineer ,

Seth here. I have gone through the items you are describing. I am stuck at the PSDK_RTOS too. Are you still having this issue?

P.S. I am still currently and actively approaching this topic on the AI. Please send some guidance if you have "conquered" this effort.
