Hi,
I was succesfull in building ghc (pulled from git) to compile for
arm-linux-androideabi!
Now using inplace/bin/ghc-stage1 -dcore-lint -debug I compiler this
Main.hs:
main = putStrLn Hello, World
I get an executable, which I can run on my android device. Unfortantly
it segfaults.

What do you mean by barely-just-works? Anything besides:
* no GHCi support and
* bad performance due to the lack of a native code generator
is probably a bug that we (the GHC maintainers in Debian) would like to
know about.
Could you help me to find a workaround for the mentioned error?
That link looks like it points to the manual for the most recent distribution,
not HEAD. The edits I put into the manual for the new family instances are not
there, for example.

One thing thats unclear (or at least implicit) about the overlapping type
families from the docs is this:
does it let me write recursive type level functions? (I really really
really want that :) )
thanks

Recursive type level functions are actually not new -- type families as they
have existed for some time can be recursive. The new overlap mechanism doesn't
really interact with the recursion feature in any interesting way. For anything
moderately interesting and recursive, though, you will have

Cool!
For some reason I had thought that wasn't previously allowed, thanks for
clarifying!
That said, the new overlapping type families should make things a bit
easier to write.
awesome

I know that it probably needs updating for Groovy. I don't think it
has many users, which makes it more challenging to keep things running
smoothly, but I'm willing to help any interested parties get it up and

Hi Cafe,
I've recently released crypto-pubkey [1][2], which provide a comprehensive
solution for public key cryptography.
Most known RSA modes (PKCS15, OAEP, PSS) are supported, and there's also DSA
and ElGamal signature support. Most of the code originally lived in
cryptocipher,
