The continued diary of an experienced C++ programmer. Thoughts on C++ and other languages I play with, Emacs, functional, non functional and sometimes non-functioning programming.

The Windows build of Emacs 24.5 doesn’t ship with SSL and TLS support out of the box. Normally that’s not that much of a problem until you are trying to access marmalade-repo or have org2blog talk to your own blog via SSL/TLS.

Adding SSL and TLS support to the Windows builds of Emacs is easy. SSL/TLS support in the official Emacs build for Windows isn’t enabled because it doesn’t ship with the necessary support libraries, but you can get pre-built binaries from the ezwinports project on Sourceforge. Installation is simple - grab the desired binaries (I used gnutls, but there’s also an older openssl build available) and extract them into the root directory of your Emacs install. The directory layout is the same and mimics the standard Unix directory layout so everything ends up in the correct place.

After the next restart of Emacs, a quick

M-: (gnutls-available-p)

should result in ’t’, showing you that Emacs has found the gnutls binaries. All of a sudden, org2blog can talk to my blog again and I’m finally set up the same way I am on the other OSs I use.

ezwinports has a whole bunch of other useful libraries available as well, like libpng, so check it out.

One caveat - the ezwinports libraries are 32 bit libraries so they work fine with the official 32 bit build of Emacs for Windows, but you need to look into alternatives if you use a 64 bit build.
