[pkg-uWSGI-devel] Bug#892074: uwsgi: FTBFS with ruby2.5 as default

[Antonio Terceiro]

Source: uwsgi
Version: 2.0.15-10.2
Severity: serious
Justification: fails to build from source

I am about to upload ruby-defaults to unstable, switching the default
Ruby to ruby2.5. With that in place, uwsgi fails to build from source
like this:

[...]
 CFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security" CPPFLAGS="-Wdate-time -D_FORTIFY_SOURCE=2" LDFLAGS="-Wl,-z,relro" python uwsgiconfig.py -v --plugin plugins/rack_ruby23 debian/buildconf/uwsgi-plugin.ini rack_ruby23
