Subject RE: [users@httpd] How do I pick up correct version of SSL
Date Tue, 23 Feb 2010 11:24:39 GMT

Sorry for the confusion Igor and thanks to both of u.

Using configure, I set the path to openssl 0.9.8k that I built in a separate directory before
rebuild of apaci
./configure --prefix=/usr/local/apache2 --enable-modules=most --enable-mods-shared=all --disable-authz-default
--disable-dav --enable-proxy --enable-ssl --with-ssl=${BUILDIR}/../openssl-0.9.8k --with-mpm=worker
--enable-so --enable-rewrite --enable-log-config --with-included-apr

However, checking the maps file, it uses /lib/ 

In the other hand, it seems that shared lib of of 0.9.8k is not generated as part of openssl
built. Moreover, due to redhat limitation the version installed by the OS can not be overwritten.

Do I have to set an option to set another path for installation of openssl not to overwrite
the OS version?
How can I get the .so file as output of the openssl build?

Once done, I suppose that I should add the path of the newly build openssl so file in LD_LIBRARY_PATH

Now, I understand the "Enjoy" of Sander... ;-)

Hi Paul
Sorry it's the other way round.  The ldd command tells you which 
libraries that the linker will call at runtime when the binary is 
Igor was correct
If you want to specify the library you need to set LD_LIBRARY_PATH to 
include the library you are after before execution
To check what libraries will be linked, use ldd as Igor has 
To check what libraries have been linked by a running PID, take a 
look at /proc/<pid>/maps

Run the ldd command against httpd executive 
  binary too see the linked libraries

    Thanks for the clarification onthis topic... but any tip how we can 
    cope with httpd linked with openssl 0.9.8x on redhat?

    there is a requirement of openssl not to overwrite the default version 
    provided with the OS. 

How do we specify to httpd the library to take 
    at runtime?
How can we check which library is taken by httpd at 

Thanks a lot for help,
