Can't Make Nginx since upgrading to OpenSSL 1.0.1

[Ted Phillips]

Earlier today I upgraded my OpenSSL from 0.9.9 to 1.0.1c
# openssl version
shows the new version number:
# OpenSSL 1.0.1c 10 May 2012

I am currently on Nginx 1.1.19 built against OpenSSL 0.9.9. I have performed a number of successful upgrades to Nginx (started on 0.8.43).

When attempting to install 1.3.0 or 1.2.0, I use my normal
# ./configure --sbin-path=/sbin --with-http_ssl_module
# make

And get the following:
# ...
# objs/src/http/modules/ngx_http_upstream_ip_hash_module.o \
# objs/src/http/modules/ngx_http_upstream_keepalive_module.o \
# objs/ngx_modules.o \

# collect2: ld returned 1 exit status
# make[1]: * [objs/nginx] Error 1
# make[1]: Leaving directory `/root/nginx-1.3.0/nginx-1.2.0'
# make: * [build] Error 2

Please help, I would like to be able to upgrade in the future.

From the error shown it looks like you have new openssl headers but still old libssl.so library in the library path. Make sure to remove old openssl library (and install new library if there are no new libssl.so available).

Thanks, seems I got so used to Nginx's upgrade process I forgot to move the symlink to the new .so
