Hi,

I'm getting the below error message when trying to perform "configtest" after upgrading apache to 2.4.12 version with success.

/home/apache/bin/httpd: symbol lookup error: /home/apache/bin/httpd: undefined symbol: SSL_CONF_CTX_new

Note: I received the error after recently upgrading my openssl to 1.0.2.

Just wonder how to get rid of the error message.

Running on Ubuntu Server 12.04.05 LTS 32bit.

Thank you very much in advance

At the moment under Linux you have to use OpenSSL 1.0.1 to compile apache. I tried several times, but that does not work out with 1.0.2

OK. I have to revert back to my old version openssl-1.0.1k then.

hmm... I wonder if this error is to do with the fact that httpd-2.4.12 doesn't support openssl-1.0.2 just yet.

Thank you for your reply.

James,

Just for your info, it seems to work happily for httpd-2.4.12 and openssl-1.0.2 on ubuntu server 14.04 LTS. I don't get any error message when performing a "configtest" command but "syntax ok".

Cheers

James,

Sorry, you're right. I'm still getting the same error message even on ubuntu server 14.04 64bit. I must've seen it wrongly.

Cheers

First I thought it runs, but then I enabled mod_ssl and it crashed.
