Question

I’m creating a web application that requires the use of the perl module Crypt-SSLeay. This module has a dependency of needing OpenSSL headers. Since my Linux server has neither I went through these steps to install, but I’m receiving an error that’s hard to understand (see below) because of my limited experience.

Server Information:
Running Oracle Enterprise Linux
Linux version 2.6.18-194.11.4.0.1.el5 ([e-mail]) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48))

Steps to replicate the issue:
Downloaded and extracted openssl 0.9.8r from here and ran the following commands (after going to the directory)

./config --openssldir=/usr/local/openssl
make
make test
sudo make install

Downloaded and extracted the Crypt-SSLeay module from here and then ran the following commands (after going to the directory)

 perl Makefile.PL
 make

I receive the following error after I run “make”:

I’m not sure what I need to do when I recompile OpenSSL to get this module to work. Any help appreciated.

That looks like an error in the OpenSSL build itself. Are you sure your distribution doesn’t provide the OpenSSL headers? (And i’m sure you already had the libraries, right?)

The headers are in a package called “openssl-devel” on RedHat IIRC, should be the same for Oracle Enterprise Linux (I guess, never used that).

If you do find the headers in your distro’s packages, don’t forget to un-install your custom build (remove the files manually if the OpenSSL Makefile doesn’t have an uninstall target).
