Question

Today I’ve been working on setting up extra VPS clones and I’ve run into a strange and frustrating compile time error with the latest nginx development version (0.9.6).

I’m running Ubuntu 10.04.2 LTS x86_64, however, I’ve upgraded GCC to 4.6.1. ./configure runs without errors, but upon running make -j4 I’m presented with the following error:

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 objs \
-o objs/src/core/ngx_open_file_cache.o \

I’ve tried adding –with–cc-opt=”-W” to the ./configure options but without result. Can anyone please shed some light on this show stopper?

Many, many thanks in advance!

A nicer way to do this is to pass the following to ./configure

--with-cc-opt=-Wno-error
