I recently reconfigured a build environment for a mingw-built application but I ran into issues on Windows 10 caused by a #define _WIN32_WINNT in C:\msys64\mingw32\i686-w64-mingw32\include\_mingw.h
In my installation it targets WINNT 0x0601 #ifndef _WIN32_WINNT #define _WIN32_WINNT 0x601 #endif My colleague's setup targets 0x0502. In my understanding 0x0502 is still the default: https://mingw-w64.org/doku.php/configure https://github.com/mirror/mingw-w64/blob/d72c4fe62568a216d52dca47ca8bace4e220d84f/mingw-w64-headers/configure.ac#L156 I installed msys2-x86_64-20161025.exe and updated via pacman and installed i.e. base-devel and pacman -S mingw-w64-i686-gcc. How could I have ended up with 0x0601? What's the recommended way to control this and prevent issues like this? Store an archive of msys2/mingw32 somewhere? Add -D_WIN32_WINNT=0x0502 to our makefile? Here's a (subset) of possible updates for my colleague's setup, my guess is that the change is in one of these: mingw-w64-i686-ca-certificates 20170211-2 -> 20180409-1 mingw-w64-i686-crt-git 6.0.0.5176.1fd1a585-1 -> 7.0.0.5285.7b2baaf8-1 mingw-w64-i686-expat 2.2.5-1 -> 2.2.6-1 mingw-w64-i686-gcc 7.3.0-2 -> 7.4.0-1 mingw-w64-i686-gcc-libs 7.3.0-2 -> 7.4.0-1 mingw-w64-i686-gdb 8.1-3 -> 8.2.1-1 mingw-w64-i686-gettext 0.19.8.1-4 -> 0.19.8.1-7 mingw-w64-i686-headers-git 6.0.0.5176.1fd1a585-1 -> 7.0.0.5285.7b2baaf8-1 mingw-w64-i686-libwinpthread-git 6.0.0.5174.9726fb77-1 -> 7.0.0.5273.3e5acf5d-1 mingw-w64-i686-ncurses 6.1.20180526-1 -> 6.1.20180908-1 mingw-w64-i686-openssl 1.0.2.o-1 -> 1.1.1.a-1 mingw-w64-i686-p11-kit 0.23.12-1 -> 0.23.14-1 mingw-w64-i686-python3 3.7.0-10 -> 3.7.2-1 mingw-w64-i686-sqlite3 3.24.0-1 -> 3.26.0-1 mingw-w64-i686-tcl 8.6.8-1 -> 8.6.9-2 mingw-w64-i686-tk 8.6.8-1 -> 8.6.9.1-1 mingw-w64-i686-winpthreads-git 6.0.0.5174.9726fb77-1 -> 7.0.0.5273.3e5acf5d-1 mingw-w64-i686-zlib 1.2.11-3 -> 1.2.11-5 Please advise, I would like to know how this is supposed to work for msys2/mingw32 Kind regards Disclaimer: This mail transmission and any attached files are confidential and are intended for the addressee only.
