The source is also available via a GitHub mirror. There are various versions including stable as well as unstable versions. The OpenSSL source code can be downloaded from OpenSSL Source Tarballs or any suitable ftp mirror. Also see Why aren't tools like 'autoconf' and 'libtool' used? in the OpenSSL FAQ.
OpenSSL's build system does not rely upon autotools or libtool. If you are building OpenSSL 1.1.0 and above, then you will also need PERL 5.10 or higher (see README.PERL for details). Also, the second generation is more platform agnostic and uses templates to produce a final, top level build file ( Makefile, descrip.mms, what have you).Īfter you configure and build the library, you should always perform a make test to ensure the library performs as expected under its self tests. For example, the second generation abandons the monolithic Configure and places individual configurations in the Configurations directory. The instructions are similar, but not the same. Second is the build system for OpenSSL 1.1.0 and above. First is the build system used in OpenSSL 1.0.2 and below. There are two generations of build system. But the library proper must be built with a C compiler. Later, once the library is built, it is OK to create user programs with a C++ compiler. You must use a C compiler to build the OpenSSL library. You should avoid custom build systems because they often miss details, like each architecture and platform has a unique opensslconf.h and bn.h generated by Configure. Once configured, you use make to build the library. Configuration will allow the library to set up the recursive makefiles from. OpenSSL uses a custom build system to configure the library.

If you have questions about what you are doing or seeing, then you should consult INSTALL since it contains the commands and specifies the behavior by the development team. The following page is a combination of the INSTALL file provided with the OpenSSL library and notes from the field.
