When the reproducible=+fixfilepath feature is enabled (either through
DEB_BUILD_OPTIONS, or using a dpkg that enables this by default),
gloo fails to build from source:

  
http://qa-logs.debian.net/2020/09/26.fixfilepath/gloo_0.0~git20200724.fe2ad9c-2_unstable_fixfilepath.log

While the "fixfilepath" feature is not currently enabled by
dpkg-buildflags by default, it may become the default at some point in
the future, and can by triggered manually by setting
DEB_BUILD_OPTIONS=reproducible=+fixfilepath in the build environment.

More information about this issue is available at:

I have not identified the exact cause of this issue for
gloo, but a common triggering issue is test suites
expectinfg __FILE__ to resolve to an absolute path.

The attached patch works around this issue by disabling the fixfilepath
feature in debian/rules using DEB_BUILD_MAINT_OPTIONS=-fixfilepath.

Thanks for maintaining gloo!

live well,
