Can't compile since 0.8.33 on CentOS

Now that I examine this, it’s treating warnings as errors. Ideally
this wouldn’t be a warning either, but what could be going on to make
this force fail?

0.8.33 = no problem
0.8.34 = problem
0.8.35 = problem

OS info:

Linux foo 2.6.18-164.11.1.el5 #1 SMP Wed Jan 20 07:32:21 EST 2010
x86_64 x86_64 x86_64 GNU/Linux
CentOS 5.4 x86_64 all up to date

Where it breaks during “make”

nginx uses -Werror by default

Known issue, --without-http-cache breaks this way. You may either
patch it (patch is trivial and was already posted here[1]) or just
compile it with cache.

It’s an easy to fix buf.
You get the warning only when caching is disabled.

Ouch. Please fix this in 0.8.36 :slight_smile: heh
