Aha! That sounds very plausible. I’ll try. Maybe it’s a path-ordering thing.
It would be very cool if ‘configure’ checked that ‘find’ was the find it was expecting, not Windows find. Dunno how to do that, but that check would have saved us a lot of time.
(For most other utils, weget, curl etc, there is no Windows program with the same name. But for ‘find’, there is.)

Hi Simon,
I think you’re right,
That pattern in the error is the one we pass to find
find "${base_dir}" -name "*.tar.xz" -exec tar xfJ {} \;
on line 334 of configure.ac which is supposed to unpack the files.
That the download script doesn’t output nothing makes sense now since the hashes of the files match.
I *think* what’s going on here is that for some reason you don’t have findutils installed and it’s instead using
The windows “find” utility, which generates that error.
C:\Users\Tamar>find *.tar.xz
File not found - *.tar.xz
Try re-installing findutils, pacman -S findutils, and if find –version doesn’t return the findutils one check your PATH settings.
Cheers,
Tamar

It’s bizarre that pacman won’t let us downgrade curl!
I don’t know how to do that with pacman, so instead maybe try:
pacman -S wget
wget -qO - http://repo.msys2.org/msys/x86_64/libcurl-7.48.0-1-x86_64.pkg.tar.xz<https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2frepo.msys2.org%2fmsys%2fx86_64%2flibcurl-7.48.0-1-x86_64.pkg.tar.xz&data=01%7c01%7csimonpj%40064d.mgd.microsoft.com%7c4debde5eddb94a48303a08d3a00911b9%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=IjWobiKnhta%2fW00gDkxHQXhR2iJAp4IBD7U5dRH1p%2fA%3d> | tar xJ -C /usr --strip-components=1

I tried this. All three commands succeeded, the latter two with no output at all. But once more “./configure” fails with the same message “File not found - *.tar.xz”. It is a bizarre message isn’t it?
A lot of files are there:
/c/code/HEAD$ ls ghc-tarballs/mingw-w64/
x86_64

mingw-w64-x86_64-zlib-1.2.8-8-any.pkg.tar.xz
/c/code/HEAD$ ls ghc-tarballs/perl/
ghc-perl-1.tar.gz
All I need is for ‘configure’ to get on and un-tar them! Maybe the problem isn’t with curl at all?

Hi Simon,
I’m not sure what’s going on there.
I updated my curl to 7.49.1 and I am experiencing the same silent death (--version doesn’t even work for me then which is weird).
In any case, downgrading back to 7.48.0 worked for me.
I don’t know how to do that with pacman, so instead maybe try:
pacman -S wget
wget -qO - http://repo.msys2.org/msys/x86_64/libcurl-7.48.0-1-x86_64.pkg.tar.xz<https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2frepo.msys2.org%2fmsys%2fx86_64%2flibcurl-7.48.0-1-x86_64.pkg.tar.xz&data=01%7c01%7csimonpj%40064d.mgd.microsoft.com%7c4debde5eddb94a48303a08d3a00911b9%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=IjWobiKnhta%2fW00gDkxHQXhR2iJAp4IBD7U5dRH1p%2fA%3d> | tar xJ -C /usr --strip-components=1

If it doesn’t work, to upgrade again to 7.49.1 you can just do pacman -S curl libcurl
Kind Regards,
Tamar

Actually I had the command right; copy/paste somehow removed the underscore.
And curl –version does report
curl --version
curl 7.49.1 (x86_64-pc-msys)
so it should not be necessary anyway.
But ./configure still fails with
checking for path to top of build tree... C:/code/HEAD
configure: Checking for Windows toolchain tarballs...
configure: Extracting Windows toolchain from archives (may take a while)...
File not found - *.tar.xz
Meanwhile
mk/get-win32-tarballs.sh download x86_64
completes after 1 second, with no messages of any kind.
What next?!
Thanks
Simon

Hi Simon,
You’re missing an underscore in the command (there’s one between x86 and 64),
It’s pacman -R mingw-w64-x86_64-curl<https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2frepo.msys2.org%2fmingw%2fx86_64%2fmingw-w64-x86_64-curl-7.43.0-2-any.pkg.tar.xz&data=01%7c01%7csimonpj%40064d.mgd.microsoft.com%7c29ea9918454d48869fcb08d39f917b40%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=1LRbkuT6t%2f%2bEyWa1nfWXuraL5Y%2faGwB9n6b6bRwBb3I%3d>
This is only needed if curl --version reports anything other than x86_64-pc-msys.
After that you need to install the normal msys curl with pacman -S curl
You don’t have to run configure everytime to test either, you can just run
mk/get-win32-tarballs.sh download x86_64
from the root and it should just download the packages only if everything is setup correctly.
Also don’t forget to do a pacman -Sy to update the repositories. Couldn’t gather from your email if you did this already.
Kind Regards,
Tamar

Friends
I want to thank everyone who has responded – very helpful!
Thanks to your help I am making progress
· I re-installed msys64 from scratch, this time following the instructions on the GHC wiki rather than the msys2 page. By doing update-core; then pacman -Su; then pacman -Su again, I got a clean install. Very good!
Getting a shell between each step is tricky.
o The first shell is gotten with mingw64.bat
o After update-core, that file is gone; you have to use msys2_shell.cmd I think
o After pacman -Su we get mingw64.exe, which we can use thereafter.
· My slow-start problem appears to have gone away. I adopted the fix from
you may be hitting a long standing issue some computers have in which the domain controller is being hit for every invocation of commands, causing a slowdown https://github.com/Alexpux/MSYS2-packages/issues/138 , Solution 2 from https://gist.github.com/k-takata/9b8d143f0f3fef5abdab<https://na01.safelinks.protection.outlook.com/?url=https%3a%2f%2fgist.github.com%2fk-takata%2f9b8d143f0f3fef5abdab&data=01%7c01%7csimonpj%40064d.mgd.microsoft.com%7cdd4588e2f3ff499367c308d39f535acd%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=KQFg%2f83I5Vj%2bS4ivgSvAI%2bpt3A04ulMjbO%2bbIrsb%2btQ%3d> seems to fix it for most people.
I am not absolutely certain that was the problem, but things seem ok now. I also excluded c:/msys64 from my antivirus check.
· Emacs too is now working normally. Hurrah
So that’s all good.
Now I’m stuck on the windows tarballs download thing. I get
configure: Checking for Windows toolchain tarballs...
configure: Extracting Windows toolchain from archives (may take a while)...
File not found - *.tar.xz
I tried both the things described on the wiki<https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows>:
Pacman -R mingw-w64-x86_64-curl
error: target not found: mingw-w64-x86_64-curl
For the other I did the two mkdir things, and tried ./configure again, but got the same error message as above.
So I’m stuck again, but further forward. Can you advise me?
Thanks!
Simon
