What should I do to get curl support?
OS is Linux Ubuntu 12.10.
Install libcurl-dev
http://packages.ubuntu.com/de/lucid/libcurl-dev
Add "-L-lcurl" to your commandline
Thanks for help. Correct answer was here:

What's about:

No, I wrote very simple example. I have 10 "from" types and a lot
of different "bar" functions. Your way will be more painful then
explicit conversion.
