Add -dev suffix to requirements on README #26

Open cscherrer opened 10 years ago

cscherrer commented 10 years ago

The readme page suggests installing libblas and liblapack. But there are no such packages! I assume you probably meant to have a -dev suffix on each of these. Yes?

cartazio commented 10 years ago

I think so :) it also varies with the distro right?

cscherrer commented 10 years ago

Probably. But you say apt-get install, so I assumed you were thinking Ubuntu. I'd guess any Debian-based distro probably uses the same or very similar names, but I'm not sure.

cartazio commented 10 years ago

well, yeah, but i'm on a mac usually :)

if we're going to make it accurate, having a table of "distro names X pkg names to install" is probably the right way to roll

cscherrer commented 10 years ago

Looks like it's *-dev on Debian and *-devel on Redhat. Not sure about others.

Rufflewind commented 10 years ago

Note that some distributions don't make the distinction between dev and non-dev packages. On Arch Linux, they are just blas and lapack.

cartazio commented 10 years ago

@Rufflewind you make a good point (hence my "we should list all the options if we're going to list some of them" stance)

I see you started your own blas binding! Can I invite you to contrib to hblas? (though if you have your own design, thats cool too). (i'll soon be giving a higher level api for hblas via my numerical project, wellposed/numerical-core is the core piece for now)

Rufflewind commented 10 years ago

I was writing a C binding generator in Haskell to handle Fortran call conventions and name mangling. It became redundant when I discovered the CBlas wrapper.

I'm currently porting some numerical code to Haskell, so I'd interested in writing FFI wrappers for Blas functions.

cartazio commented 10 years ago

@Rufflewind well, theres a lot of easy wrapping to be done on the blas front, youre welcome to help out, the pullrequests by @archblob are some decent examples of what those wrappers might look like.

If you're really comfy with lapack, i'd love some help figuring out how to give those nice high level wrappers that are still full powered.

I should also mention i'm amidst the release engineering for a nicer array layer that will interop with hblas, you can see it at https://github.com/wellposed/numerical-core currently

Rufflewind commented 10 years ago

I noticed you don't seem to be using hsc or c2hs to generate the FFI bindings. Wouldn't these tools make writing them a bit easier?

cartazio commented 10 years ago

@Rufflewind lets have this chat on a new ticket perhaps? no one has convinced me that using either will make things easier, I still have to write down the name and the type signature either way! and then I immediately have a more complex configuration process. Right now theres zero configuration time logic
