Problem with Upgrading Apache to 2.2.22 with ssl

Apache installation Error



7:09 pm on Mar 28, 2012 (gmt 0)

I have several systems running on RHEL 5.7 (32bit) with following:
Apache 2.2.21 with ssl enabled
OpenSSL 1.0.0e

I wanted to upgrade to:
Apache 2.2.22 with ssl enabled
OpenSSL 1.0.1

I ahave done the following:

#OpenSLL installation (default location /usr/local/ssl)
make test
make install
#Apache Install
./configure \
--with-ssl=/usr/local/ssl \
--enable-ssl \
--enable-modules="all" \
--enable-mods-shared="most" \

# I am getting the following error:

Is there a config.log file and what it says?

Appreciate your response. sorry about the delayd response, I was busy to find the solution. I tried several different things but nothing is working. Here is the config.log file. I am getting the error message that the post is too large. I am going to paste it in parts.

My config file is 36 pages long. This portal does not allow me to paste all the text and there is no way to attach the text file. Id there any way that I can email this file to you?

come on, I am sure there are many apache gurus gone thru this...!

it's strange, are you receiving notifications from this forum on PMs or not?

sorry, I did not see the PM. I just sent you the config.log file.

I wanted to provide some more info:
Same install script works with
But I get the same error with OpenSSL-1.0.0h and OpenSSL-1.0.1.

So I was able to upgrade from httpd-2.2.21/OpenSSL-1.0.0e to httpd-2.2.22/OpenSSL-1.0.0g. I would like to upgrade to OpenSSL-1.0.1

Looks like the openssl library is the problem. I see in the log

dso_dlfcn.c:(.text+0x43): undefined reference to `dlsym'
dso_dlfcn.c:(.text+0x4d): undefined reference to `dlclose'

So something is wrong with the LIBS argument that you setup.

Thanks for taking a look at the log file.

I am not really sure what I am doing wrong. I am using the same script to install OpenSSL as well as Apache. As I mentioned earlier that things went fine with OpenSSL-1.0.0e, OpenSSL-1.0.0f and OpenSSL-1.0.0g. This problem started to appear with OpenSSL-1.0.0h and OpenSSL-1.0.1.

Same thing is happening on around 10+ servers.
Any further steps to troubleshoot/fix would be much appreciated.

seems the openssl you use seems has a dependency on the libdl, so see if it builds by setting LIBS=-ldl

Thanks again for the reply.

I am sorry, I am not clear about what you are trying to say. Are you saying that I should try to build OpenSSL with LIBS=-ldl or with httpd. I tried with both and i got the following responses.

[root@indb2 openssl-1.0.0h]> ./config --LIBS=-ldl
Operating system: i686-whatever-linux2
Configuring for linux-elf
Usage: .......

[root@indb2 httpd-2.2.22]> ./configure --with-ssl=/usr/local/ssl --enable-ssl --enable-modules="all" --enable-mods-shared="most" --LIBS=-ldl
configure: error: unrecognized option: `--LIBS=-ldl'
Try `./configure --help' for more information.

that's for the httpd to be built with libdl

env LDFLAGS="-ldl" ./configure --with-ssl=/usr/local/ssl --enable-ssl --enable-modules="all" --enable-mods-shared="most"

what happens if you try to configure with the above?


6:29 pm on Apr 4, 2012 (gmt 0)

That did the trick. You are a genius my friend.
Can you please explain what really happened?

There are functions in libdl used for dynamic linking and it was required to be present from the logs. It may not be the only problem though. You have to check the functionality of the apache you just built.


2:52 pm on Apr 5, 2012 (gmt 0)

So far everything is working fine. Is there anything specific you want me to test/check?


4:21 pm on Apr 5, 2012 (gmt 0)

WebmasterWorld Senior Member 5+ Year Member

Ok it's possible that everything works just keep an eye in the server logs.


7:07 pm on Apr 5, 2012 (gmt 0)

Thanks, appreciate your valuable help. I will let you know if anything is wrong.
