Package: libnginx-mod-http-ndk-dev
Version: 1:0.3.3-1
There is a module package for Nginx, which worked as well since
this FTBFS bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067364
The upstream contains this section in config:
https://github.com/owasp-modsecurity/ModSecurity-nginx/blob/master/config#L15
ngx_feature_test='printf("hello");'
The problem is when the buildpackage process starts, I got this
error:
hecking for ModSecurity library ... not found
checking for ModSecurity library in /usr/local/modsecurity ... not found
./configure: error: ngx_http_modsecurity_module requires the ModSecurity
library.
see sbuild.log:
http://qa-logs.debian.net/2024/03/19/libnginx-mod-http-modsecurity_1.0.3-1_unstable.log
I investigated the root issue, and I found this message in
obj-x86_64-linux-gnu/autoconf.err:
/home/airween/src/libnginx-mod-http-modsecurity-1.0.3/obj-x86_64-linux-gnu/autotest.c:7:5:

}
If I add a patch (via d/series) which adds this header correctly,
then everything is fine, the package builds as well.
The upstream isn't touched since 6 years (the mentioned file), so
I guess something is changed in libnginx-mod-http-ndk-dev (if it
is responsible to produce the test codes - I guess).
Note, that there isn't any user report in upstream regarding this
problem, actually I can reproduce this only in Debian.
Sorry if I'm wrong.
Thanks,
a.

The issue is solved, in dpkg version 1.22.6, the compiler flag
-Werror=implicit-function-declaration was enabled by default for
all architectures in build flags.
We need to handle the FTBFS issue in bug 1067364 with adding a
patch to the package.
Btw it should be fixed in upstream too.
Thanks for all.
a.
