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” gcc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Wunused-function -Wunused-variable -Wunused-value -Werror -g -I src/core -I src/event -I src/event/modules -I src/os/unix -I /usr/include/libxml2 -I objs -I src/http -I src/http/modules -o objs/src/http/modules/ngx\_http\_fastcgi\_module.o src/http/modules/ngx\_http\_fastcgi\_module.c cc1: warnings being treated as errors src/http/modules/ngx\_http\_fastcgi\_module.c: In function ‘ngx\_http\_fastcgi\_process\_header’: src/http/modules/ngx\_http\_fastcgi\_module.c:1104: warning: unused variable ‘fh’ make[1]: \*\*\* [objs/src/http/modules/ngx\_http\_fastcgi\_module.o] Error 1 make[1]: Leaving directory `/usr/src/build/nginx-0.8.35’ configure and output: ./configure --conf-path=/etc/nginx/nginx.conf --prefix=/usr –user=www-data --group=www-data –error-log-path=/var/log/nginx/error.log –pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock –http-log-path=/var/log/nginx/access.log –http-client-body-temp-path=/var/lib/nginx/body –http-proxy-temp-path=/var/lib/nginx/proxy –http-fastcgi-temp-path=/var/lib/nginx/fastcgi –with-http\_stub\_status\_module --with-openssl= --with-md5= –with-http\_gzip\_static\_module --without-mail\_pop3\_module –without-mail\_smtp\_module --without-mail\_imap\_module –without-http-cache --with-http\_flv\_module --with-http\_ssl\_module –with-http\_dav\_module --with-http\_realip\_module –with-http\_xslt\_module --with-debug checking for OS -

You may either patch it (patch is trivial and was already posted here[1]) or just compile it with cache.

You get the warning only when caching is disabled. Regards Manlio ---
