Hi Kiman,


There are many different places which you can use in order to add them.

One example, you can put them in configure/CONFIG_SITE

USR_INCLUDES += -I/usr/include/CL
USR_LDFLAGS += -lOpenCL
PROD_LDLIBS += -lOpenCL

or
USR_INCLUDES += -I/usr/include/CL
USR_LDFLAGS += `pkg-config --libs OpenCL`
PROD_LDLIBS += `pkg-config --libs OpenCL`

And you can also put the similar things in yourApps/src/Makefile where you compile your source codes with opencl api functions.



Some hints which you may get in the following codes:

https://github.com/epics-modules/ecmc/blob/master/devEcmcSup/Makefile#L25

https://github.com/epics-modules/ecmc/blob/master/devEcmcSup/Makefile#L29

https://github.com/epics-modules/asyn/blob/master/asyn/Makefile#L36

https://github.com/epics-modules/ecmc/blob/master/configure/CONFIG_SITE#L38


HTH,
Han

Hello All,

I have a plan to use the OpenCL API and library with epics IOC.

The platform is Linux 64bit.

My build option is to use the “xcpp” compiler instead of the “gcc”.

The “xcpp" compiler is Xilinx C++ compiler which is based on GNU compiler collection.

With below build options:

CXXFLAGS += -std=c++14

LDFLAGS += -lOpenCL

My questions are:

 1. Do I need re-build base using the “xcpp” compiler?

               If yes, which base configuration files need to change?

 2. Or only my IOC application need to add the OpenCL library with
    "xcpp" compiler?

Thanks,

Kiman
