# Reads the file `Recipe' to determine the list of generated
# executables and their component objects. Then reads the source
# files to compute #include dependencies. Finally, writes out the
# various target Makefiles.

# PuTTY specifics which could still do with removing:
#  - Mac makefile is not portabilised at all. Include directories
#    are hardwired, and also the libraries are fixed. This is
#    mainly because I was too scared to go anywhere near it.
#  - sbcsgen.pl is still run at startup.

    ##-- 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.
