Perl Inline C code inside nginx Perl module

[Ondrej Jombik]

We have some proprietary code in C language, which we cannot convert
into Perl. We would like to use this C code in Perl nginx module. Code
runs well under Perl's Inline C.

However when I try to run Inline C code in nginx Perl module, it does
not work. Not only this code does not work, in fact no Inline C code
work inside Perl nginx environment.

For example, look at this very simple Perl module inlinetest.pm:

package inlinetest;
use strict;
use nginx;

$ENV{'PATH'} = '/bin/:/usr/bin/';
use Inline Config =>
 		DIRECTORY => '/tmp/';
use Inline "C" => <<'...';
 	void test_fnc(int num)
 	{
 		fprintf(stderr, "%d\n", num);
 	}
...

sub handler {
 	$request->send_http_header('text/html');
 	return OK;
}

1;

Related nginx configuration is pretty standard:

     perl_modules /etc/nginx/perl/;
     perl_require inlinetest.pm;

     server {
         listen 127.0.0.1:80;
         location /auth {
             perl inlinetest::handler;
         }
     }

As you can see in my example, I am not even using or calling test_fnc()
yet. But Perl code simply fails on startup with this error message:

-- Unit nginx.service has begun starting up.
nginx[20011]: nginx: [emerg] require_pv("inlinetest.pm") failed: "Running Mkbootstrap for inlinetest_0cff

Does anyone has any idea why it fails to run under nginx Perl?
