[Message part 1 (text/plain, inline)]

Source: eiskaltdcpp
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The RPATH contains the build path resulting in different buildid:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/eiskaltdcpp.html

The attached patch to debian/rules passes
-DCMAKE_BUILD_RPATH_USE_ORIGIN=ON via the CMAKEOPTS variable.  used in
the dh_auto_configure override, which should use a relative path for
RPATH.

With this patch applied, eiskaltdcpp should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining eiskaltdcpp!

live well,
  vagrant

Subject: [PATCH] debian/rules: Pass -DCMAKE_BUILD_RPATH_USE_ORIGIN=ON via
 CMAKEOPTS variable.

This avoids embedding the full path in RPATH, which triggers BuildId
differences.
