Hi @ostueker,
Thanks for the interest. We've not really documented the msys2/m2
and msys2/m2w64
packages, those links are about as much as we've got, but they've been in use for about 9 months now and are serving their purpose well from my perspective. They are used by the R
infrastructure, Rpy2
, theano
. Some packages are occasionally used as build dependencies in recipes when posix stuff is needed.
One thing to note is that here, -w64
in no way means 'not provided for 32-bit', it's just to differentiate mingw-w64
from the original mingw.org
which has no support for 64-bit at all. Every msys2/m2
and msys2/m2w64
package is provided for both architectures.
You can see the recipes for all of them here: https://github.com/mingwandroid/conda-recipes/tree/master/msys2
Because a meta-package is a normal package just without any content of its own beyond its dependencies there's no way to query which packages are and which are not meta-packages. Some of the packages are meta-packages in MSYS2
, and only 3 are bespoke conda
meta-packages. They are:
m2-base:
'm2-bash',
'm2-bash-completion',
'm2-catgets',
'm2-coreutils',
'm2-dash',
'm2-file',
'm2-filesystem',
'm2-findutils',
'm2-gawk',
'm2-gcc-libs',
'm2-grep',
'm2-gzip',
'm2-inetutils',
'm2-info',
'm2-less',
'm2-mintty',
'm2-msys2-launcher-git',
'm2-msys2-runtime',
'm2-ncurses',
'm2-sed',
'm2-time',
'm2-ttyrec',
'm2-tzcode',
'm2-util-linux',
'm2-which',
'm2-libxml2'
posix: m2-base +
'm2-make',
'm2-tar',
'm2-zip',
'm2-unzip',
'm2-diffutils'
m2w64-toolchain:
'm2w64-binutils',
'm2w64-crt-git',
'm2w64-gcc',
'm2w64-gcc-ada',
'm2w64-gcc-fortran',
'm2w64-gcc-libgfortran',
'm2w64-gcc-libs',
'm2w64-gcc-objc',
'm2w64-headers-git',
'm2w64-libmangle-git',
'm2w64-libwinpthread-git',
'm2w64-make',
'm2w64-pkg-config',
'm2w64-tools-git',
'm2w64-winpthreads-git'
.. but really, even here I should be using pacman
's groups instead of recreating the packages. There is not a single root meta-package for all the MSYS2
packages, because there are around 200 of them and I didn't think people would want all of them at once. Is there a reason to want this?
The script I mentioned at https://github.com/conda-forge/conda-forge.github.io/issues/112 to convert packages from MSYS2
to conda
I've still not got round to tidying up and getting into conda skeleton
. It requires libalpm
and pyalpm
which are currently on https://anaconda.org/rdonnelly for macOS and Linux only.
Because MSYS2
is a rolling release it's sometimes not entirely stable. For this reason, we do not plan to sync with it frequently. We call each resync an msys2-epoch
and so far there's only been one of those so far, the initial one. Recently, a number of good fixes have gone into it though so soon might be a good time for us to consider updating everything.
Sorry to bring this up. Some tutorials/posts suggest installing both m2w64-toolchain and mingw64. Is there any point in installing m2w64-toolchain if I already have mingw64 toolchain (through msys2 or mingw-w64 project)?

@mingwandroid Are there any plans to resync with msys2 again? Specifically I'm curious about the potential of easily conda-installing a version of gcc that supports C++17.
I came across the conda repo with msys2 and mingw64 packages[1] and two related GitHub issues [2,3] after @mingwandroid 's work was mentioned on the Software Carpentry list[4].
I am intrigued by the integration of msys2 packages into the conda repositories and eager to use them.
Is there any documentation on these packages, i.e. which of them are meta-packages that can serve as root of the dependency tree?
I found that packages posix and m2w64-toolchain seem to install a large subset (but not all) of the available packages.
