[uml-devel] UML static linking and embedded library

[-- Attachment #1.1: Type: text/plain, Size: 1441 bytes --]

Hello Richard and others,

I currently have 2 severity E(rrors) lintian rejects for the build I am
preparing for Debian.

The details for both the rejects are explained at:

http://lintian.debian.org/tags/binary-or-shlib-defines-rpath.html
http://lintian.debian.org/tags/embedded-library.html


Richard, Is this something that can be worked out upstream?

If there were decisions cautiously made for a reason, I can work it out
with an override to lintian. Just that I want to check out with you guys
first.



Ritesh

Solving the first issue is straight forward.
For the second one I've to think a bit why Jeff took the current
static linking approach.

Expect patches for both issues in 3.5. :-)

Thanks. Can you prepare the patch?

We are going to ship Debian 7 (Wheezy) with kernel v3.2. Based on what
you prepare, I will backport it.

Thanks,
Ritesh

the rpath one should be as simple as the attached one but honestly I
kind of recall there was a reason for RPATH to be defined. Maybe that
reason is no longer valid though...
