[pkg-uWSGI-devel] Bug#854535: uwsgi: dpkg-buildpackage fails due to open with O_TMPFILE

[Masahiro Yamada]

Package: uwsgi
Version: 2.0.7-1
Severity: serious
Tags: patch
Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

When I run dpkg-buildpackage for uwsgi, it fails with the following error.

 $ sudo apt-get source uwsgi
 $ cd uwsgi-2.0.7
 $ sudo dpkg-buildpackage -us -uc

    ^

This error is caused by updated libc6.
The changelog in libc6(2.19-18+deb8u6) says as follows.

    - Fix open and openat functions with O_TMPFILE.  Closes: #832521.

I found a fix to this issue in upstream.
