[avr-llvm-devel] Issues Building From Source

[Victor A. <vic...@wi...>]

Hi all,

I'm brand new to the list and to the project. I have been hearing a lot of
chatter about Clang lately, was curious and that led me here. My
configuration is Ubuntu 12.04

So I start following the directions in the docs/gettingstarted.html
file<http://avr-llvm.svn.sourceforge.net/viewvc/avr-llvm/llvm/trunk/docs/gettingstarted.html?revision=164>.
Everything was going fine (ish... patching reported some failures) until I
hit the steps:

$ cd ..
$ mkdir build
$ cd ../build

build$ ../llvm/configure --prefix=$HOME/usr/avr-llvm/
--disable-optimized --enable-targets=avr
build$ make

First of all I think "$HOME/usr/avr-llvm/" should be "$HOME/avr-llvm/". I
also think the line "cd ../build" should just say "cd build". But anyway I
get the following error after  some crunching (even after those "fixes" I
mentioned).

...
> checking whether byte ordering is bigendian... no
> configure: error: Unrecognized target avr
> configure: error: ../../../llvm/projects/sample/configure failed for
> projects/sample


I followed all the preceding steps (copy/paste) of patching and what not,
but apparently something is out of sync with the documentation, the
patches, and the repositories? Some more details about the preceding step
outputs are as follows:

*llvm checkout*: Checked out revision 159885.
*avr-llvm checkout*: Checked out revision 197.
*patch* output:

I can't imagine those FAILED messages are expected... so the problem is
probably related I'm guessing.

*rsync*: terminates silently.

Can anyone lend me a hand continuing to make progress building?

Kind Regards,

Vic
