Re[2]: Help! Can't build HEAD

Hi Simon, I had that very issue a few days ago, but saw this thread too late. For me it was enough to cd into utils/hpc and do a `git checkout .`.

Ah.

rm utils/hpc git submodule update

does the job. Who would have guessed that? Maybe this thread will help others.

Could hadrian have avoided this, perhaps?

Anyway, I'm rolling again, thanks

Oh I didn't know you had to say "--init". Anyway that fails

Perhaps even `git submodule update --init`.

You need to run `git submodule update` I think.

Aargh! I can't build HEAD!

I get this: ./hadrian/build Up to date ]0;Starting... ]0;Finished in 0.04s Error, file does not exist and

no rule available:

...

utils/hpc/hpc-bin.cabal Build failed.

This is after hadrian/build clean ./boot ./configure

I'm very stalled. All my trees are borked. Can anyone help?
