This recursive package definition really demonstrates how magical Guix
can be :-)
Try invoking:
./pre-inst-env guix build mingw-w64-{x86_64,i686}{,-winpthreads}
* gnu/packages/mingw.scm (make-mingw-w64): Add XGCC, XBINUTILS optional
arguments to specify using a non-default cross-compiler/binutils. Add
WITH-WINPTHREADS? optional argument to allow building with winpthreads
support. Adjust accordingly for the new arguments.
(mingw-w64-i686-winpthreads, mingw-w64-x86_64-winpthreads): Add
variables.
* gnu/packages/cross-base.scm (native-libc): Add XGCC, XBINUTILS
key arugments and pass to MAKE-MINGW-W64.
(cross-libc): Pass XGCC and XBINUTILS to NATIVE-LIBC.
This patch parameterizes previously hard-coded instances of
i686-w64-mingw32, adding support for x86_64-w64-mingw32.
* gnu/packages/mingw.scm (make-mingw-w64): New procedure.
(mingw-w64-i686, mingw-w64-x86_64): New variables.
(%mingw-triplet): Remove.
(mingw-w64): Update to point to 'mingw-w64-i686'.
* gnu/packages/cross-base.scm (cross-gcc): Use 'libc' keyword argument
if specified, instead of treating it as a boolean.
(native-libc): Return the correct mingw-w64 depending on machine
specified in target.
* gnu/packages/bootstrap.scm (glibc-dynamic-linker): Add "x86_64-mingw".
* gnu/build/cross-toolchain.scm (set-cross-path/mingw): Replace
hardcoded 'i686-w64-mingw32' instances with 'target' keyword argument.
(cross-gcc-build-phases): Update accordingly; use 'target-mingw?'
implementation of target checking and add commentary.
* gnu/ci.scm (%cross-targets): Add "x86_64-w64-mingw32".
MinGW-w64 was forked (in rather dramatic fashion) from the original
MinGW. The two projects remain distinct and MinGW-w64 seems by far the
actively developed of the two.
* gnu/packages/mingw.scm (mingw-w64)[home-page]: Point to the correct
upstream. Use HTTPS.
[description]: Expand and briefly note the relationship between the
two projects. Use @dfn.
