RE: Resolving Windows 64-bit linker issues

Hi Darren, I'm afraid I don't off the top of my head. I've never had to look at that file yet. On my way to work this morning I was reading up on what mingw64 uses .refptr for. So now I understand at least that part. But I'm afraid I can't offer any advice on how to tackle it in GHC at the moment.

Do you have any thoughts or advice on approaching changes to the existing PE code in Linker.c? I'm wondering if this was destined to be extended into support for PE+ given the absence of .refptr and $. Cheers, Darren On Mon, Feb 16, 2015 at 9:10 PM, Tamar Christina wrote:

Hi Darren,

I don’t actually know what the status of these issues are. I think one of the tasks we had set out to do was actually checking on these tickets and their progress.

Gintautas was doing most of the mingw64 build stuff. I don’t know if the cygwin64 link stuff has been looked at by anyone since I think we’re all mostly using mingw64.

I have two issues I’m working on atm, both related to the RTS. But if there’s anything I can do to help then just let me know.

Cheers, Tamar

To expand on that (let's see if I can do this without accidentally sending again, oops!):

Roman, I will get in touch with you on a separate email thread to see if we can find an optimal way to coordinate, something that satisfies our schedules and needs. Others please feel free to bug me any time by email ( dedgrant@gmail.com) or on freenode #ghc as dedgrant, PST hours.

In the meantime I'll be auditing some of the related backlogged tickets on trac. If there's something I can do to help further the goal of a Windows Task Force page, please let me know.

Pleased to meet everyone!

Cheers, Darren

Excellent! We have a Windows Task Force, consisting roughly of the folk in cc. So they would be the first group to ask.

(I think it would be very helpful to have a Windows Task Force home

that it’s easier to find the group.)

thanks for helping with Windows.

Hi all,

I notice there are a series of related long-standing issues subject to particular cygwin64 quirks, and I'd like to offer time to help resolve

if possible

At this point I've had some exposure to the GHC build process (7.8.3), and have poked around the GHC linker to gain some low level insight.

Would anyone be available to fill me in on the current state of affairs with mingw64 GHCi linking? For instance, is there ongoing work, or perhaps a preferred direction but no available developer bandwidth to proceed?

Thank you.

Cheers,

Darren
