Hamish Coleman 4438f1aa2a added mingw test platform (#829) ... * Provide a minimal reimplementation of our autoconf, to try windows builds * Try building with windows * Fix thinko in spelling * Ensure shell script runs inside a shell * Add a hack to aid include discovery * Just keep adding tech debt... * Assume that we will have slashes in some of the replacement strings and avoid that char with sed * Restore one slash * Hack around the tools makefile interdependancy bug * A correct cflags include hack for each compile dir * Ensure we link against winsock (note, even though this says 32bit, it should link the 64bit library ... I think) * Bad link ordering if we dont use LDLIBS * Remove unused make variable * Remove makefile duplication using inheritance (this does mean you can no longer cd tools; make, but must do make tools) * Add missing library for win32 * Show OS variable * Make hack autoconf more robust for tests on non gitlab runners * Remove no longer used substitutions from hack autoconf * Add missing include path to tools under win32 * Build the win32 subdir when the compiler is Msys * The different subdirs have different dependancies * Ensure we can find the include files * Fix library link ordering * Ensure the tools dir can find the special win32 lib * Deal with the differing basic type sizes on both linux/64bit and windows/64bit * Document the steps to mimic the github windows/mingw build locally - to allow for simpler debugging * Ensure branch name in instructions matches my test branch name * Clarify the shell needed to build with mingw * Since the makefile depends on knowing the OS, raise a fatal error if we cannot determine this * Handling different compile environments is hard. - Linux: sane and reasonable results for both uname -s (=Linux) and uname -o (=GNU/Linux) - Windows/Mingw: insane results for uname -s (=MSYS_NT-$MAJOR.$MINOR-$BUILDNR) but sane results for uname -o (Msys) - Macos: sane results for uname -s (=Darwin) but does not support uname -o at all * Revamp the way that Mingw is detected * Avoid attempting to generate gcovr report when running under windows * Whoops, isolate the right step * Fix spelling mistake * win32/Makefile: Remove unused setting and add comment * ensure that all win32 includes use the same expected path * Allow simpler cross compilation by letting configure pass the CC and AR environment through * Avoid multiple '_CRT_SECURE_NO_WARNINGS redefined' warnings * Convert to a consolidated CONFIG_TARGET variable to select any different compile options * Use the more generic printf defines to avoid warnings on mingw * Update mingw build docs * English better for reader happy make * Address a number of mingw compiler warnings * Fix Visual C compile * Be sure to document some of the hacky nature of the mingw build		2021-10-06 00:52:15 +05:45
