   It is a cross-compilation toolchain: the compiler runs on a machine and creates executables for another one. In this case, it runs on Ubuntu x86 computers and builds software for Ubuntu ARM.

   A native toolchain that runs and builds for Ubuntu ARM is easlily available by apt-get, but cross-compilation toolchains are a bit harder to obtain, hence this package.

   Can you explain a bit more about this toolchain: Does it build for ubuntu-arm targets, or just work on ubuntu-arm?

   Bear with me here. I have a few more questions :)

   Does the cross compiler assume that the machine used for compilation is setup in the same way as the target – for example with respect to shared libraries?

   I have a 9.10 rootfs that I'm running on a Beagle-alike board (IGEPv2) – I'd like to be able to cross compile apps for it (I need to develop some CORBA apps) but I'd rather not do all the compilation on the board itself.

   So far, it seems like your package will be a very good solution for this – but I am not sure of the caveats/pitfalls. Do I need to ensure the systems are set up identically? If not, are there specific details about how to set up the specifications of the target environment? In fact, is there a bunch of documentation somewhere I can churn through?

   Thanks :)

   Hi,

   I've got the binary and unpacked it to /usr/local/ but I'm not so sure what's the best way to *use* it

   Could you provide an example of how, for example, to compile an autotools package using the cross compiler – for example, something like ./configure –target=arm-none-linux-gnueabi –host=arm-none-linux-gnueabi

   Which is what I would do with the only cross compiler with which I am familiar!

   Any thanks would be really appreciated – I'm sure it's just a little 'getting started' thing that I'm missing :(

   It can be used exactly like any other cross toolchain, there is nothing special in it except that it uses Ubuntu’s libraries and compiler versions. And yes, a certain knowledge of cross compiling is assumed. I’m thinking to write an introductory article about cross compilation to help people who are not experienced in this area, but it won’t be anytime soon as I have other priorities at the moment.

   Notice that this is a plain toolchain and NOT a cross-compilation environment. You are required to setup the rootfs, environment, libraries, dependencies and the emulator yourself, or please consider to install the toolchain within scratchbox2 (or other cross-compilation environment of your choice) to make things easier for you.
