[viff-devel] error while installing viff

[Thomas Jakobsen]

Hi

You need to install both OpenSSL and pyOpenSSL. Win32 binaries for
OpenSSL can be found at

   http://www.slproweb.com/products/Win32OpenSSL.html

I've only tested VIFF installation on WinXP and I had to use the
v0.9.8g OpenSSL installer rather than the
v0.9.8h installer. I don't know if that's the case with Vista, too.

The installation instructions on the VIFF webpage should definitely be
more specific about the need for installing OpenSSL separately. this.
I'll fix that soon.

Regards,
Thomas
