R SIG Debian - Jul 2011 - A question on the GCC toolchain compiled for ARM

Hello,

We are security researchers at Vrije Universiteit Amsterdam. We have a
scenario where we need to be able to compile a C source on the Android
device itself. Hence, I came upon the R project's Android port:

http://rwiki.sciviews.org/doku.php?id=getting-started:installation:android

I could not find who created the "android gcc", so I guess R porting
for
Debian is the closest mailing list I could find that is related.

Good news is that I've tried the gcc on the device and it works like a
charm.
question is, the size is really large. We have simple C files with no
threading and the like.
Just bionic + linux system headers + lib math. Nothing else.

I was wondering whether I could strip the toolchain down to a bare minimum?
Or what were your steps while building it in the first place, so that I can
exclude things not needed up front?

If this is not the right place, please direct me to the right forum or the
team who did the work on the android gcc port.

Cheers,
Earlence

I'd talk to the Debian Arm porters starting with the info here: 

    http://www.debian.org/ports/arm/

The different ports go through different ebbs and flows depending on hardware
availability and viability; I think the arm / armel folks are reasonably
active.

The mailing which you contacted here is mostly concerned with using R on
Debian / Ubuntu which almost invariably limits the userbase to x86 and amd64
architectures. 

Hth, Dirk
