Slackware64-current, which I am running has the most up to date versions of the packages and is at http://ftp.slackware.com/pub/slackware/slackware64-current or ones of its mirrors. For a VM/BMM installation there are DVD and USB installation images here http://ftp.slackware.com/pub/slackware/slackware64-current/isolinux and here respectively http://ftp.slackware.com/pub/slackware/slackware64-current/usb-and-pxe-installers.

Once the installer is running it is pretty straightforward to do a full install (which includes boost, swig, gcc etc. etc.). It just needs to be pointed to a download of the packages from http://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/. I can't remember but it might be able to access them directly over the net via http://.

That does sound quite old. Could you point me to its location?

Thanks
