Update commit hash every time it changes, not just when CMake is re-ran The commit hash is now properly updated every time it gets changed, and not just when CMake gets re-ran. For this to work, we need to use a few CMake tricks. We add a custom target with ADD_CUSTOM_TARGET(), which is apparently always considered out-of-date (but I had to add a BYPRODUCTS line to get it to actually work), and we use the target to run a .cmake file every time we build. Also, VVVVVV needs to depend on this custom target, to ensure that the game gets built AFTER the version gets generated - otherwise there'll be an error. So we do an ADD_DEPENDENCIES() after the ADD_EXECUTABLE() for VVVVVV. This file, version.cmake, is just the Version.h.out generation that I added previously, but the important thing about all of this is that if the contents of Version.h.out doesn't change, and thus if the commit hash hasn't changed, then CMake will never recompile and relink anything at all. (At least with the Ninja generator.) On a small note, since the Version.h.out generation is now a separate script that is guaranteed to get ran on every single build, while the Git FIND_PACKAGE() gets ran only at configure time, it is possible for the cached path of the Git executable to get out of date. Fixing this requires a simple re-configure (ideally), but in case it wasn't fixed, the INTERIM_COMMIT and COMMIT_DATE variables would get set to empty strings instead of containing a value. To prevent this from happening, I've removed ERROR_QUIET from the EXECUTE_PROCESS() calls in version.cmake, because it's better to explicitly error if the Git executable wasn't found than implicitly carry on like nothing happened.

Fix C/C++ standards being unset for VVVVVV target if CMake is >= 3.1.3 So, it turns out we weren't quite done fighting CMake yet... To accommodate #869 (and actually also #272), the C standard was raised from C90 to C99. This turned out to require a bit of a fight with the CentOS CI's CMake version to get it to set the flags we wanted (and to not overwrite them later). Eventually the fix was to move the block that sets the standards to later in the file, which was done in 24353a54bb40665b64a93faebfb2ebd96cd0f6b5. As it apparently turns out, if your CMake is at least 3.1.3 and `CMAKE_<LANG>_STANDARD` is used instead of the workaround, the standard setting now has an effect on the third party libraries, but not on VVVVVV itself. The cause is (probably) the phrase "if it is set when a target is created" in the CMake documentation - the `CMAKE_<LANG>_STANDARD` values have to come before the VVVVVV target is defined. In other words, the compiler's default C/C++ standard will be used, probably something like C17 and C++17. As I can confirm with `__cplusplus` and `__STDC_VERSION__` with my recent-enough CMake. If I force the pre-3.1.3 workaround to be used, everything is compiled with C99/C++98 as expected; and the `-fno-exceptions` `-fno-rtti` flags appear everywhere regardless of version. So my fix is to make the CMakeLists a little less complex by simplifying away the `CMAKE_<LANG>_STANDARD` and `CMAKE_<LANG>_EXTENSIONS`, and always using the workaround regardless of CMake version. There's nothing wrong with the workaround, the same thing is also done for `-fno-exceptions` `-fno-rtti`, and it's good to have a less complicated CMakeLists that doesn't do different and unexpected things for different versions.

Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Add `/MT` flag for MSVC This flag makes it so the MSVC runtime libraries are statically linked. This avoids needing Windows users to have these libraries installed. Apparently /MT stands for "MultiThreaded", and there's a bit of a history there where originally by default you could only have a single-threaded library, and then the multi-threaded flags were added in later. First I tried doing target_compile_options on VVVVVV, but then got a linker error. Then I tried doing add_compile_options because I figured /MT had to be applied everywhere, and it seemed to work, but it still linked to the runtime libraries. Apparently it was being overridden. Then I tried target_compile_options again but this time did it to everything, and that linked correctly and also removed the runtime dependency. I would've tried using the MSVC_RUNTIME_LIBRARY property - along with the CMP0091 policy - but those were only introduced in CMake 3.15. You can verify that a binary is built without dependencies by installing LLVM and running llvm-readobj --needed-libs path/to/binary. This is the output for a binary with runtime dependencies: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll MSVCP140.dll SDL2.dll SHELL32.dll USER32.dll VCRUNTIME140.dll api-ms-win-crt-heap-l1-1-0.dll api-ms-win-crt-locale-l1-1-0.dll api-ms-win-crt-math-l1-1-0.dll api-ms-win-crt-runtime-l1-1-0.dll api-ms-win-crt-stdio-l1-1-0.dll api-ms-win-crt-string-l1-1-0.dll api-ms-win-crt-time-l1-1-0.dll api-ms-win-crt-utility-l1-1-0.dll ] And this is the output for a binary with those dependencies having been statically-linked in: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll SDL2.dll SHELL32.dll USER32.dll ]
