##-- 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.
# - for older versions of the VS libraries you may also have to
# set EXTRA_console and/or EXTRA_windows to the name of an
# object file manually extracted from one of those libraries.
# * This is because old VS seems to manage its startup code by
# having libcmt.lib contain lots of *crt0.obj objects, one
# for each possible user entry point (main, WinMain and the
# wide-char versions of both), of which the linker arranges
# to include the right one by special-case code. But lld
# only seems to mimic half of that code - it does include
# the right crt0 object, but it doesn't also deliberately
# _avoid_ including the _wrong_ ones, and since all those
# objects define a common set of global symbols for other
# parts of the library to use, lld may well select an
# arbitrary one of them the first time it sees a reference
# to one of those global symbols, and then later also select
# the _right_ one for the application's entry point, causing
# a multiple-definitions crash.
# * So the workaround is to explicitly include the right
# *crt0.obj file on the linker command line before lld even
# begins searching libraries. Hence, for a console
# application, you might extract crt0.obj from the library
# in question and set EXTRA_console=crt0.obj, and for a GUI
# application, do the same with wincrt0.obj. Then this
# makefile will include the right one of those objects
# alongside the matching /subsystem linker option.
