1.0.2+ wont build

Server NGINX

In auto/cc/gcc, you have:

CFLAGS="$CFLAGS -Werror"

and

CFLAGS="$CFLAGS -Wunused-variable"

so when building 1.0.2+ you receive this error:

gcc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter
-Wunused-function -Wunused-variable -Wunused-value -Werror -g -O2 -I
src/core -I src/event -I src/event/modules -I src/os/unix -I objs
-o objs/src/event/ngx_event_openssl.o
src/event/ngx_event_openssl.c
src/event/ngx_event_openssl.c: In function ‘ngx_ssl_get_cached_session’:
src/event/ngx_event_openssl.c:1690:31: error: variable ‘c’ set but not
used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors

Try 1.0.4?

Yes, thank you for report (though it’s about gcc 4.6+, not about
nginx 1.0.2+). Try the attached patch.

Oops, forgot to actually attach patch. Let me try again.

Obvious workaround is to use

./configure --with-cc-opt="-Wno-unused-but-set-variable"

Just throwing that data point out there.
1.0.1 will fail with gcc 4.6 as well, when built without
–with-debug option and with ssl.

Yea I realized that after I sent it, but forgot to send the followup.
I’m currently running 1.0.1 built with gcc 4.6.0 and it builds fine,
but 1.0.1 also fails to build in 4.6.1.

Just throwing that data point out there.
