Msys2 64: progress

[Simon Peyton Jones]

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 | tar xJ -C /usr --strip-components=1
wget -qO - http://repo.msys2.org/msys/x86_64/curl-7.48.0-1-x86_64.pkg.tar.xz | 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
/c/code/HEAD$ ls ghc-tarballs/mingw-w64/x86_64/
mingw-w64-x86_64-binutils-2.25.1-1-any.pkg.tar.xz
mingw-w64-x86_64-crt-git-5.0.0.4531.49c7046-1-any.pkg.tar.xz
mingw-w64-x86_64-gcc-5.2.0-3-any.pkg.tar.xz

mingw-w64-x86_64-libiconv-1.14-5-any.pkg.tar.xz
mingw-w64-x86_64-libwinpthread-git-5.0.0.4538.78dca70-1-any.pkg.tar.xz
mingw-w64-x86_64-mpc-1.0.3-2-any.pkg.tar.xz
mingw-w64-x86_64-mpfr-3.1.3.p0-2-any.pkg.tar.xz
mingw-w64-x86_64-winpthreads-git-5.0.0.4538.78dca70-1-any.pkg.tar.xz
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 | tar xJ -C /usr --strip-components=1
wget -qO - http://repo.msys2.org/msys/x86_64/curl-7.48.0-1-x86_64.pkg.tar.xz | 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
