It seems like -fviaC does not do *anything* at all in the current
version of GHC. I am yet to try my luck with an older version of GHC. 

There has been some effort to bootstrap GHC using hugs and nhc98, which
I am following with interest:

Which may still be sufficient to produce a bootstrap binary for -fasm, if
you're willing to put in the effort to get a native port.

That's very nice to hear.

After reading your message, I tried compiling a simple program using the
'-fviaC'. But it looks like, on newer GHC it is deprecated and is going
to be removed soon.

I will try that. Thanks.

I updated the README with the usage instructions
https://github.com/joe9/idris-9front-backend . Please let me know if
that does not help.

Basically, generate the .c file using Idris on linux (or, another
platform that Idris runs on). Compile the rts and this generated .c
file using ape on 9front.

A caveat, I tested with simple Hello World code. Not sure how well
it works for something more complicated though.

Thanks

Can you detail the process?

I'd like to give it a try on Jehanne (which is built with gcc).

I have the posix version of the rts working on 9front. The default C
backend generated code compiled and runs on 9front. I generated the c
code on linux though.

As a next step, I want to take it further and make the rts and backend
work with the 9front native C compiler/linker. I presume that this
will help make it easy to FFI with the native C libraries (bio,
thread, etc.) and stay closer to the plan 9 libraries' behaviour.

That is a good idea. Native GHC on 9front seems to be a daunting task
as the GHC IO manager's behaviour might not be compatible with the
9front syscall behaviour, imho. But, I have no clue of the GHC
internals, so, it might be an easy task.

Maybe, ghc can run with the linux-emu package?

Thanks

Sorry for the confusion. I did not realize that there was an Idris
OS. I am referring to http://www.idris-lang.org/ , Idris Language.

Thanks

That is a reference to the Idris OS -- by Whitesmiths Ltd. (P.J. Plauger).

For the record, David Stanhope did the port, and created the boot ROMs and
the cartridge to boot Idris.  He also designed and built an Ethernet card
for the ST.  I was a novice programmer/sysadm lucky enough to have one the
best hardware and software engineers I've ever met as a mentor.  My
contributions to the project can be characterized as logistical support
(documentation, support, etc.).

I think you may be confusing Idris the language and Idris the OS.

Don't you need GHC to compile Idris? 

Afaik, there is no Plan 9 port of GHC. And GHC is self hosted. Perhaps
one should approach it by creating a plan 9 binary from another OS and
use that to compile GHC?
