Compilation error on CentOS-5.7

Hi,

Can you please help me overcome this problem. I’m trying to compile
Nginx + nginx_udplog_module
from source but I get this error: cc1: warnings being treated as
errors

I tried with nginx-1.0.0 the version in our production servers and *
nginx-1.0.12* the latest stable version.

Best Regards

Hello,
This is because nginx is compiled with the -Werror flag, remove this
from
your objs/Makefile file, and you should be fine.

I.e. warning options set by nginx (notably “-Wall …
-Wno-unused-parameter”) are overriden by your “-Wall” which comes
later, and this results in compilation failure due to “-Werror”
also set by nginx.

Not passing “-Wall” by hand will fix this while still ensure that
warnings unexpected in the nginx source code will be fatal.

Hi Maxim,

Thanks a lot for your expertise. I removed the -Wall option and
everything worked perfectly, without the need to remove -Werror

Best Regards.
Really appreciate your support.

Hi,

I was able to compile nginx alone without problems. however it doesn’t
compile when I add nginx_udplog_module-1.0.0 support “*
–add-module=/root/nginx_udplog_module-1.0.0*”
any hints ?

If you need the syslog feature, maybe you can give Tengine (
http://tengine.taobao.org) a try? It is a nginx distribution with native
syslog support: http://tengine.taobao.org/document/http_log.html

It looks like the udplog module version you are using is way too
old and doesn’t contain this 2 years old fix for and API change
in nginx 0.8.32:

https://github.com/vkholodkov/nginx-udplog-module/commit/e7b8145b96ae9f5be94f0ab0008a8c59cd13c7b8

You may want to get more recent one from Valery’s github.

Maxim D.

Hi Maxim,

Thanks for your reply.
Actually as I was asked to ad support for the nginx_udplog_module
module
I copied the configuration options from nginx -V output.
I really appreciate your advise and I’ll give it a try right away.

Best Regards
