Hello,
I am posting to begin a thread regarding the native compilation and execution of OpenCL code on an ARM Android device, namely the HTC One M8.
I have used the app Linux Deploy to install a Debian desktop environment alongside Android, sharing the same Linux kernel but supplying different runtime libraries. Additionally, I have installed gcc/g++, Code::Blocks, and the OpenCL ICD and header files necessary to compile a native binary.
My intent is to continue developing a graphics render algorithm, but if I can get a working Android binary from g++ on a GNU toolchain, I would be happy to share generalized source code so that others can do the same with some simplicity.
Currently, I have success compiling a binary with shared libraries for GNU/Linux, but it does not detect the OpenCL devices on my system. I tried statically linking my application, but it refuses to link OpenCL statically.
The way I see it, there are two ways to solve my problem:
1) I assume Debian cannot see devices due to a driver issue, but I could be wrong, and I don't believe appropriate GNU drivers exist at this time. (Please correct me in a response if you know this to be false.) I have talked briefly with some of the folks from the Freedreno project, and it seems the OpenCL compiler is the biggest missing piece between the driver and the hardware. Unfortunately, I do not know if a working driver would even solve the issue in my case.
2) Compile binary with Android shared libraries. This may be most easily done with Eclipse, but I prefer Code::Blocks, so if the libraries could be linked in, then it may be trivial to change IDEs. I suppose it depends entirely on how the NDK handles compilation.
Option 2 is most likely the best course of action. I intend to publish my progress in milestones. Discuss.
