Hi all,

I am getting entries like this in my nginx error log, and I have no idea  
what they might mean.

(I am also getting /phpmyadmin/index.php served as a file, and not  
passed to php-fastcgi, and they might be related).

Regards

Ian

What does nginx -V show?

Also you may try running with MALLOC\_CHECK\_ set to 2 (see

> **[The GNU C Library - GNU Project - Free Software Foundation (FSF)](https://sourceware.org/glibc/manual/)**

for details) and provide backtrace.

See [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/NginxDebugging) for general nginx  
debugging guidelines.

Have you tried with the distro’s versions of pcre, zlib, and openssl?

I’ll take a look at that tomorrow if I can.

^ you’ve manually built pcre, zlib and openssl, despite the fact that  
all of  
these are provided by your distro? 🙂

First option: Install the -dev packages for all of nginx’s dependencies.  
An  
easy way to do this is “apt-get build-dep nginx” (as long as you have  
some  
deb-src entries in your sources.list).

Second option: It’s highly unlikely that you’re the first person to want  
the  
most up-to-date nginx for Ubuntu 10.04 LTS… surely someone has made  
some  
packages for you already? Ta-da!

No. How would I do that?  
pcre and zlib are not packages apt-get recognises.

openssl claims to be at latest (0.9.8k 25 mar 2009).

Hi,

As Jeff suggested above, either by doing apt-get build-dep, which will  
install all the dependencies required to build nginx.

Or you can use apt-cache search to find packages.  
apt-cache search pcre shows me that the full package name is  
libpcre3-dev.

Try to ./configure without specifying where the libs are, and if  
something is missing the error message should help you figure out what  
to install in your distro.

Cheers,

Matthieu.

BTW, I highly suggest using aptitude in place of apt-get for all your  
package needs on Debian/Ubuntu. You’d certainly have found these  
packages on your own had you used “aptitude search” in place of  
“apt-cache search”.

Yes, they just follow the weird Debian naming “conventions”:

# aptitude install libpcre3-dev libssl-dev zlib1g-dev

Did that - and it recompiled just fine. I’ve not finished testing yet,  
but things are looking good so far.  
phpmyadmin is working, and no crashes.

Thanks Jeff. I need the long polling module, so I have to compile  
myself.

And thanks to everyone else who contributed. I leaned more about linux’  
tools.  
This was only my second dive into compiling under linux.
