What I meant originally was more along the lines of "the package description
isn't sufficient, the package name has to be made clearer". Currently the
mingw-w64 package's description is
"MinGW-w64 provides a development and runtime environment for 32- and 64bit
Windows applications using the GNU Compiler Collection (gcc)."
which seems to me quite similar to the description you quote - the only
missing information is the x86/x64 nomenclature. It might also make sense to
mention the "Windows API" as it is now known (see
http://msdn.microsoft.com/en-us/library/Aa383723 for details).
I'm actually undecided regarding the -win32 and -win64 suffixes: while it's
probably a good thing to have at least win32 in the 32-bit package names,
using those two suffixes is restrictive at least in theory: the API itself is
pretty much the same, and Windows supports x86, x64 (x86_64), IA-64 (Itanium)
and presumably some form of ARM processors soon... So your original -i686 and
-x86_64 might be more future-proof. The MinGW-w64 project's site has links to
"WIN32" and "WIN64" downloads, but none of the packages use those terms. The
automated builds use "mingw-w32" for the 32-bit target package, "mingw-w64"
for the 64-bit target package, and i686/x86_64 is used to indicate the host
CPU! rubenvb's personal builds use i686-w64-mingw32/x86_64-w64-mingw32 to
specify the target, and sezero's follow the automated builds' naming
So there's precedent for using mingw-w32 and mingw-w64, but that would
probably generate more confusion with the similarity to mingw32. I'd vote for
mingw-w64-i686 and mingw-w64-x86_64 in the end, based on the following:
* the upstream project's name is MinGW-w64, hence the mingw-w64 name
* the target CPUs are currently i686 and x86_64
* we don't differentiate Win32 and Win64 because there's no real difference
in the APIs
* this allows future support for ARM and/or IA-64 without renaming existing
In the Windows world i?86 is known as x86 and x86_64 is x64, so those names
should appear in the description.
How about the following base description:
MinGW-w64 provides a development and runtime environment for 32- and 64-bit
(x86 and x64) Windows applications using the Windows API and the GNU
Compiler Collection (gcc).
This metapackage provides the full MinGW-w64 development environment.
(The binutils, gcc and gdb packages would be updated to suit.)
As far as the packages are concerned, the mingw-w64 source package would
produce mingw-w64, mingw-w64-i686, mingw-w64-x86_64, the corresponding three
-dev variants and a single -tools package (since that varies only by host
architecture); gcc-mingw-w64 would produce all the gcc-based packages
(gcc-mingw-w64, gcc-mingw-w64-i686, gcc-mingw-w64-x86_64; I'm also splitting
the package up into gcc, g++, gnat, gfortran etc.) including the transitional
gcc-mingw32 package; likewise binutils-mingw-w64 and gdb-mingw-w64.
