Linking Against the System OpenSSL

There is a package in Fink called system-openssl-dev that exists to make it easier to link software against Apple's provided OpenSSL (why?). It creates symlinks in prefix/lib/system-openssl that you can use to override the flags of existing software.

In some cases, you will have to patch your package to point to the system-openssl directory, but most likely, all you will have to do to use system-openssl-dev is to set one or more of the following:

 CPPFLAGS:        -I%p/lib/system-openssl/include
 CFLAGS:          -I%p/lib/system-openssl/include
 CXXFLAGS:        -I%p/lib/system-openssl/include
 LDFLAGS:         -L%p/lib/system-openssl/lib
 LIBS:            -L%p/lib/system-openssl/lib
 PKG_CONFIG_PATH: %p/lib/system-openssl/lib/pkgconfig

Creating Upgrade Packages

Since the goal is to create packages using OpenSSL that don't have to be in the crypto/ tree, you will probably want to make upgrade packages for the old versions of your SSL packages. If you have a set of packages such as foo and foo-ssl both of which have splitoffs, you will have conflict/upgrade issues if you just make a new foo-ssl dummy package that depends on foo. Instead, the recommended practice is to create a foo-unified package.

Example: Before Unification

 Package: foo
 Depends: %N-shlibs
 Conflicts: foo-ssl
 SplitOff: <<
   Package: %N-shlibs
   Conflicts: foo-ssl-shlibs

 Package: foo-ssl
 Depends: %N-shlibs
 Conflicts: foo
 SplitOff: <<
   Package: %N-shlibs
   Conflicts: foo-shlibs

Example: After Unification

 Package: foo-unified
 Depends: %N-shlibs
 Replaces: foo (<< %v-%r), foo-ssl (<< %v-%r)
 SplitOff: <<
   Package: %N-shlibs
   Replaces: foo-shlibs (<< %v-%r), foo-ssl (<< %v-%r)
 SplitOff2: <<
   Package: foo
   Depends: %N (= %v-%r)
 SplitOff3: <<
   Package: foo-shlibs
   Depends: %N-shlibs (= %v-%r)
 SplitOff4: <<
   Package: foo-ssl
   Depends: %N (= %v-%r)
 SplitOff5: <<
   Package: foo-ssl-shlibs
   Depends: %N-shlibs (= %v-%r)

Deprecation of system-openssl-dev

OS X 10.11 has deprecated the use of a system provided OpenSSL library. While /usr/lib/libcrypto.0.9.8.dylibs and /usr/lib/libssl.0.9.8.dylib were not removed, Apple removed the OpenSSL headers in /usr/include/openssl and other compile-time files. Therefore, it is no longer possible to compile programs that use the system OpenSSL on OS X 10.11. As a result, the system-openssl-dev package is marked as available only on 10.10 and earlier. In order to accommodate this change, packages will need to transition to use Fink's OpenSSL (openssl100-dev/openssl100-shlibs as of Oct 2015) or some other SSL provider (such as GnuTLS via Fink's gnutls28/gnutls28-shlibs). Because binaries of (L)GPL packages that link to OpenSSL cannot be distributed for licensing reasons, a new value for the License: field has been created. (L)GPL packages can now be marked (as of Fink-0.39.2) as either GPL/OpenSSL or LGPL/OpenSSL so that the original license information is kept, but also note that it links to OpenSSL and therefore keep it out of the binary distribution.

The following table is a list of packages as of October 13, 2015pruned as fixed that use system-openssl-dev and need to be updated.
