[Q] Build Android using native compiler topic

All tutorials on building Android are referring to use M$ with a virtual machine and Ubuntu 64bit linux or use a computer with 64bit Ubuntu and cross toolchain installed.

I have a development board (A20) with Ubuntu 12.04 (32bit) and the arm7hf compiler installed. The manufacturer delivers an Android image along with the source code archive.

My question is:
Is it possible to re-build Android for this kind of device using this environment?

This would avoid big computers with cross compilation instead it's done with the native compiler and tools for the processor it should later run on.

Or is the use of a cross toolchain fixed by Google in the Android SDK, i.e. no possibility to build Android in the native processor environment it is intended to run on?

[C++] Compiling OpenCL application to native ARM ELF using Debian topic

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.
