Source: llvm-toolchain-3.4
Version: 1:3.4.2-13
Severity: serious
Tags: jessie sid

Justification: FTBFS in jessie on amd64

Hi,

During a rebuild of all packages in jessie (in a jessie chroot, not a
sid chroot), your package failed to build on amd64.

Relevant part (hopefully):
> g++-4.9  driver.o listener_test.o test_listener_event_description.o -Wl,-z,relro -Wl,-z,relro -L/«PKGBUILDDIR»/build-llvm/Release/lib/python2.7/site-packages/../.. -llldb  -o "test_listener_event_description"
> ../../make/Makefile.rules:268: recipe for target 'test_listener_event_description' failed
> make[3]: Leaving directory '/«PKGBUILDDIR»/lldb/test/api/multithreaded'

> stderr: /usr/bin/ld: warning: libLLVM-3.4.so.1, needed by /«PKGBUILDDIR»/build-llvm/Release/lib/python2.7/site-packages/../../liblldb.so, not found (try using -rpath or -rpath-link)

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
