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.
