Sam Lantinga 74e1dd4c 2016-11-11T13:14:00 Define _GNU_SOURCE when building SDL
Sam Lantinga 79f6ba5a 2016-11-11T03:18:16 Fixed signed/unsigned comparison warnings in Visual Studio
Sam Lantinga 40b571c9 2016-11-06T10:01:08 Fixed bug 3468 - _allshr in SDL_stdlib.c is not working properly Mark Pizzolato On Windows with Visual Studio, when building SDL as a static library using the x86 (32bit) mode, several intrinsic operations are implemented in code in SDL_stdlib.c. One of these, _allshr() is not properly implemented and fails for some input. As a result, some operations on 64bit data elements (long long) don't always work. I classified this bug as a blocker since things absolutely don't work when the affected code is invoked. The affected code is only invoked when SDL is compiled in x86 mode on Visual Studio when building a SDL as a static library. This build environment isn't common, and hence the bug hasn't been noticed previously. I reopened #2537 and mentioned this problem and provided a fix. That fix is provided again here along with test code which could be added to some of the SDL test code. This test code verifies that the x86 intrinsic routines produce the same results as the native x64 instructions which these routines emulate under the Microsoft compiler. The point of the tests is to make sure that Visual Studio x86 code produces the same results as Visual Studio x64 code. Some of the arguments (or boundary conditions) may produce different results on other compiler environments, so the tests really shouldn't be run on all compilers. The test driver only actually exercised code when the compiler defines _MSC_VER, so the driver can generically be invoked without issue.
Sam Lantinga 8109b137 2016-10-17T21:47:33 Partial fix for bug 3092 - Statically link sdl2 with /MT for msvc Mike Linford I'm also having trouble statically linking SDL2 on Visual Studio 2015 with /MT. My symptom is that memcpy is being defined twice.
Sam Lantinga 9db5e9aa 2016-10-10T02:58:29 Made #if defined(X) consistent
Sam Lantinga 6dedbc43 2016-10-10T02:58:12 Make sure we have iconv.h before building with it
Sam Lantinga 73f2c541 2016-10-07T16:44:42 Fixed bug 2885 - SDL_stdinc.h doesn't need to include iconv.h Ryan C. Gordon We still include iconv.h in SDL_stdinc.h, probably because this header might have referenced the native iconv functions and types directly. Since these are hidden behind a stable ABI now and never just a #define for the system iconv, we shouldn't need this header included from a public SDL header anymore, slowing down external apps compiles and pulling tons of stuff into the namespace.
Ryan C. Gordon 46f44f66 2016-10-04T14:25:31 Fixed potential buffer overflow in SDL_vsnprintf() (thanks, Taylor!). Fixes Bugzilla #3441. "When using internal SDL_vsnprintf(), and source string length is greater than destination, the final NULL char will be written beyond destination size. Primary issue that is SDL_strlcpy returns length of source string (SDL_PrintString()), not how much is written to destination. The destination ptr is then incremented by this length before the sanity check is done. Destination string is properly terminated, but an extra NULL char will be written beyond destination buffer length. Patch used internally is attached which fixes primary issue with SDL_strlcpy() in SDL_PrintString() and adjusts sanity checks to increment destination ptr safely."
Sam Lantinga 5333deab 2016-03-11T08:30:18 Quick fix for qsort off-by-one error.
Ryan C. Gordon 32c70cc5 2016-02-21T13:07:14 stdlib: Restored previous qsort() implementation; the licensing is resolved. Thanks to Gareth McCaughan for changing his code to the zlib license on our behalf!
Ryan C. Gordon 09ae4df5 2016-02-15T03:37:01 Another attempt to fix Windows build.
Ryan C. Gordon 18f74c6e 2016-02-15T03:21:26 Patched to compile on Visual Studio.
Ryan C. Gordon 014956ac 2016-02-15T03:16:46 Replaced SDL_qsort with public domain code from PDCLib: http://pdclib.e43.eu/
Sam Lantinga e2fd1c0f 2016-01-02T11:17:06 Backed out commit 80ce90dbc266, this causes Visual Studio build failure on buildbot
Sam Lantinga ac444cd3 2016-01-02T10:25:53 Fixed bug 3092 - Statically link sdl2 with /MT for msvc Martin Gerhardy According to https://msdn.microsoft.com/de-de/library/2kzt1wy3%28v=vs.120%29.aspx when one is using /MT for msvc compilations the libcmt.lib is already linked to the binary. This lib includes the symbol that is now guarded (see attached patch) by the #ifndef _MT.

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().
