Re: Cross-compiling Template Haskell via -fexternal-interpreter and IPC

Hi Ben, I've just found this email from almost a year ago. Sorry for ignoring it until now. Given the date it was sent I think I missed it when it was fresh while I was on vacation. Regarding the question, I have abandoned the work I was doing on getting cross-compilation for Windows to work since my employer decided a Windows build for the app we were developing could wait some time and tasked me we something else. However, I see that Moritz is working on cross-compilation right now so I'll try get some time to see if I can get his approach to work for our use-case and give some feedback or help in any way.

I agree, named pipes are probably a better plan, perhaps a better solution overall than the way we currently pass FD numbers on the command line. Do named pipes work work as expected through wine? We would have to be careful to clean them up again afterwards.

I've implemented IPC with named pipes and it appeared to work through wine but now I'm investigating an issue which causes GHC to "freeze" when talking to the external interpreter when it is not running on a TTY (ie: in a build process)

Hi Alterto,

What ever happened to this? Is there any way I can be of assistance? It would be great to get this merged.

Cheers,
