cling on Fedora 18 Beta ARM

[hamletmonkey]

Hello:

I recently bought a Cubieboard (A10 Allwinner ARM chip) on which I installed Fedora 18 Beta. Trying to compile ROOT (latest source I downloaded on Sunday) I received this error using the default llvm and clang and gcc 4.7.2-8

Is it not possbile to compile cling on ARM? Do I need to compile llvm and clang with the cling source in /llvm/tools?

Thank you.

Hi,
AFAIK we haven't tried to compile ROOT/cling on ARM. We are waiting for an ARM build machine for quite some time. Maybe Philippe can give you a hint how to fix that issue.
Cheers,
Vassil

Hi,

What are the first errors or messages?

Philippe.

I was using the default llvm and clang install, Axel says I need to use a specific number (last known good build) but I do not know how to get that from SVN.

I downloaded llvm clang and cling from SVN at work but now something is wrong and it says the folder is 6.4 Gb. I know it cannot be, as it downloaded in a few minutes.

So I think I need the correct versions of llvm, clang, and cling and apparently gcc-4.7.2-8 is missing a header. I am downloaded the upgrades now.

Does cling work on iOS ARM?

Hi,

cling can be compiled largely on iOS ARM (except that the build stops on an illegal iOS API being used by LLVM). I will be trying to get it all compiled asap.

Cheers, Fons.
