Re: [avr-llvm-devel] Issues Building From Source

[Stefan L. <ton...@us...>]

Hi,

This is also my first appearance on these mailing lists, but I've been
following this project for some time now.
First of all, a big thanks for taking care of these build problems! I
could now finally remove my own feeble attempts at fixing the patch
files locally.

I build on a VM with Ubuntu 12.04 using a Jenkins continuous
integration server (with the hope of someday helping you guys out with
keeping this project synced with llvm).
However, I still get an get an error during the build(*):

make[5]: Entering directory
`/var/lib/jenkins/jobs/avr-llvm-build/workspace/llvm/projects/compiler-rt'

Also it seems like my test-results are a bit worse than what I've seen
you get in other threads on the mailing list:
  Expected Passes    : 2136
  Expected Failures  : 12
  Unsupported Tests  : 3386
  Unexpected Failures: 210

And the since most of the failures have the following in the log, I
think the problems might be related.
- [...]/llvm/Debug+Asserts/bin/llc: : error: unable to get target for
'i386-pc-linux-gnu', see --version and --triple.
- [...]/llvm/Debug+Asserts/bin/lli: error creating EE: Unable to find
target for this triple (no targets are registered)

Does anyone have any pointers on what the compiler-rt build error
could be caused by?

Kind regards,
Stefan
