Window build broken

[Simon Peyton Jones]

I’m afraid I am not familiar enough with ld to offer a proper fix, but to get you working again:



In rules/build-package-way.mk<https://phabricator.haskell.org/D1242#790afd03> on line 154, remove the “$(if $(filter YES,$(LdIsGNULd)),-T $$($1_$2_LD_SCRIPT))” bit.

Yay.  That worked!   I can build again.

Could you possibly

·         Push that change, so that Windows builds work again.

·         Open a ticket for a full fix.  Presumably that bit of code was there for a reason, so there’s still an action outstanding.

Thanks!!

Simon

I’d hold on that this. I have just tried building myself and also hit it.



Taking a closer look, it seems that the .o file being produces isn’t an object file but an image file. It contains the standard image headers and a PE signature.



GHC is doing the right thing in error out here. I think this is coming from D1242, there’s a linker script in there driver/utils/merge_sections.ld that’s causing ld on windows to output an image file instead of an object file.

That should get It working again.

Perhaps it is.  Should I blow it away and re-install?

One other difficulty is that (before my machine change) I tried to follow the instructions on https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows to install 64-bit msys2; but I had a series of problems that Ben G was unable to get to the bottom of.  Particularly I could not run bash from emacs; the emacs shell window never got as far as a prompt.  So I backed off.  As far as I know that is still broken.

I think I have not tried the "32-bit msys2 installer" on that page.  Maybe that should be my next step?

Regardless, it's hard to see how any of this concerns the error message I was getting.  As lonetiger said, it looks very similar to https://ghc.haskell.org/trac/ghc/ticket/10437

What next?

Simon
