Thanks.

> I was a little unsure about multi-arch for the binary package that provides an executable and script in /usr/bin - there’s a private shared library that I’ve left in /usr/lib/oclgrind/ since this package isn’t co-installable across different architectures.

correct solution :-)


About abi/api stability: once you make a new upstream release, will this be compatible with the existing liboclgrind-15.5.so?
Consider new releases with varying amount of changes producing e.g.
  15.5.1  (fix a typo/a segfault/a compiler warning triggered by gcc 7.0)
  15.6    (do small changes)
  16.0    (do huge changes)
Will applications built against 15.5 be able to run with a new release without recompilation?
When do we need to rename the libclgrind-XXX package?

For example, if a security bug is found, could you (as upstream maintainer) 
provide a new upstream release that fixes this (and only this!) issue even on an old release branch?
A stable Debian release with LTS support will have a lifetime of about 5 years ...
so at some point this will several releases behind what's "current" oclgrind.
Of course updating from 15.5 to 18.3 is not possible in stable, but a 15.5.2 api-stable and abi-stable bugfix-only release should be ok.
That would have to build without requiring a package rename to liboclgrind-15.5.2.


I saw something else in the build log, looks like a missing -lllvm-something and some superfluous -lfoo -lbar ...:
(-Wl,--as-needed might help)
