Hadrian

[Simon Peyton Jones]

as a temporary workaround we could create a top-level wrapper script, say `ghc-stage1.sh` that will call Stage1 GHC with the right arguments, just like Hadrian itself does during the build.
That sound fine, thanks.   Same for ghc-stage2.sh?
My difficulty is that as of today I simply do not know how to invoke my freshly built GHC!

Hi Simon,
Apologies it's taking so long. It's not obvious how to fix this properly, and as a temporary workaround we could create a top-level wrapper script, say `ghc-stage1.sh` that will call Stage1 GHC with the right arguments, just like Hadrian itself does during the build.
Will this work for you?
Cheers,
Andrey

Andrey and other Hadrian heros
Just to say that I am 100% stalled on using Hadrian because the in-tree binary uses the wrong library files.  I reported this a few weeks ago, but it still seems unchanged
