+ ##-- Makefile for cross-compiling using clang-cl, lld-link, and
+ ## MinGW's windres for resource compilation.
+ #
+ # This makefile allows a complete Linux-based cross-compile, but
+ # using the real Visual Studio header files and libraries. In
+ # order to run it, you will need:
+ #
+ # - MinGW windres on your PATH.
+ # * On Ubuntu as of 16.04, you can apt-get install
+ # binutils-mingw-w64-x86-64 and binutils-mingw-w64-i686
+ # which will provide (respectively) 64- and 32-bit versions,
+ # under the names to which RCCMD is defined below.
+ # - clang-cl and lld-link on your PATH.
+ # * I built these from the up-to-date LLVM project trunk git
+ # repositories, as of 2017-02-05.
+ # - case-mashed copies of the Visual Studio include directories.
+ # * On a real VS installation, run vcvars32.bat and look at
+ # the resulting value of %INCLUDE%. Take a full copy of each
+ # of those directories, and inside the copy, for each
+ # include file that has an uppercase letter in its name,
+ # make a lowercased symlink to it. Additionally, one of the
+ # directories will contain files called driverspecs.h and
+ # specstrings.h, and those will need symlinks called
+ # DriverSpecs.h and SpecStrings.h.
+ # * Now, on Linux, define the environment variable INCLUDE to
+ # be a list, separated by *semicolons* (in the Windows
+ # style), of those directories, but before all of them you
+ # must also include lib/clang/5.0.0/include from the clang
+ # installation area (which contains in particular a
+ # clang-compatible stdarg.h overriding the Visual Studio
+ # one).
+ # - similarly case-mashed copies of the library directories.
+ # * Again, on a real VS installation, run vcvars32 or
+ # vcvarsx86_amd64 (as appropriate), look at %LIB%, make a
+ # copy of each directory, and provide symlinks within that
+ # directory so that all the files can be opened as
+ # lowercase.
+ # * Then set LIB to be a semicolon-separated list of those
+ # directories (but you'll need to change which set of
+ # directories depending on whether you want to do a 32-bit
+ # or 64-bit build).
+ # - for a 64-bit build, set 'Platform=x64' in the environment as
+ # well, or else on the make command line.
+ # * This is a variable understood only by this makefile - none
+ # of the tools we invoke will know it - but it's consistent
+ # with the way the VS scripts like vcvarsx86_amd64.bat set
+ # things up, and since the environment has to change
+ # _anyway_ between 32- and 64-bit builds (different set of
+ # paths in $LIB) it's reasonable to have the choice of
+ # compilation target driven by another environment variable
+ # set in parallel with that one.
