| ## Erjang session trying to compile a simple erlang file (see foo.erl below). | |
| ## | |
| ## The good news is, that the compiler (erlc hosten on erjang) runs, and the | |
| ## failure happens not during compilation but when the eshell command c("foo") | |
| ## tries to load the resulting beam file. That's a substantial chunk of erlang | |
| ## code running there. | |
| ## | |
| ## The bad news is that the written beam file is pretty bogus. Most likely has | |
| ## to do with bug(s) in binary assembly, or iolist() handling somewhere. | |

We're looking to go on vacation somewhere in Norway or Sweden in July, hoping that someone in my network can help us out. We will be 6 people, we would like some place remote in nature at a lake or beach with access to a boat the family can use for day trips. Good easy hikes/walks in the area would be nice. It is perfectly fine if it so remote that we have to bring food for a week.
If you have been a place like this, let me know.
Thanks
Kresten & Family
