15.2.0-r6

TL;DR

For most cases, you can use mingw64-ucrt-15.2.0-r6.tar.zst or .7z.

To enable shared runtime libraries, copy $prefix/lib/shared/* to $prefix/.

To build apps for Windows 11, which forces x86-64-v2 micro architecture level, you can use mingw64_v2-ucrt-15.2.0-r6.tar.zst or .7z for better performance.

• MinGW-w64: 13.0.0
• pkgconf: 2.5.1

Changes Since 15.1.0-r0

15.2.0-r6

• Upgrade GDB to 17.1.
• Fix the build logic that causes GCC still links static libgcc when shared libraries exist.
• Fix GCC’s tooldir for finding Binutils.
  • Previously, invoking GCC without prepending it to PATH would fail (cannot find Binutils); or even worse, “succeeded” with wrong Binutils (from other toolchain in PATH).

15.2.0-r5

BREAKING changes:

• The __FILE__ macro is now expanded to UTF-8 encoded string.
  • This fixes __FILE__ with -fexec-charset=<whatever>.
  • This MAY break plain printf("%s", __FILE__) without specifying execution charset, which accidentally works without UTF-8 manifest support (i.e. Windows 7).
• The UTF-8 manifest is now conforming.
  • It is compatible with all Windows versions, and thus is applied to all profiles.
  • This MAY break IDEs that determine the encoding by inspecting the manifest.

Other changes:

• Restore Windows 9x support.
  • Profile variants *_winnt40 are now migrated to *_win98.
• Upgrade Binutils to 2.45.1.
• Workaround GDB step over failure in ostream::operator<< by disabling tail call optimization in affected functions.
• Add shared runtime libraries (to profiles that target Windows NT ≥ 5.1).
  • The toolchains are kept static by default.
  • To enable shared runtime libraries, copy $prefix/lib/shared/* to $prefix/.
• Workaround CRT bugs in “double translation” that causes sanity-draining console output (e.g. “版本” → “苞纡柄菌”).
• With the fix of UTF-8 manifest conformance, the main profiles are now extended to support Windows NT 5.2 (2003) and 5.1 (XP).
  • The profile variant 32-msvcrt_win2000 is now deprecated. It will be kept in current release branches (15, 14, 13) until EOL, and instantly removed in branch 16.

15.2.0-r4

• Fix GDB XML support.
• Fix gdbserver listening port display on Windows 2000 or earlier.
• Fix Binutils error when loading bfd plugins.
• Fix duplicated files when extracting zstd-compressed tarball with 7z.

15.2.0-r3

• Make pkgconf default to static link.

15.2.0-r2

• Add pkgconf (for upcoming library packages).

15.2.0-r1

• Enable OpenMP.

15.2.0-r0

• Upgrade GCC to 15.2.0.
• Upgrade Binutils to 2.45.
• Enable Fortran support in cross compiler.
• Reorganize micro architecture.
  • “mingw64_v2” profiles added with -march=x86-64-v2 (sse4.2, 2008) and -O2 (instead of -Os).
  • “mingw32” profiles now built with -march=pentium4 (sse2, 2000) and -mfpmath=sse.
  • “mingw32_686” and “mingw32_486” profiles added with -march=i686 (cmov, 1995) and -march=i486 (atomic, 1989) respectively (legacy OS only).

15.1.0-r3

• Fix libintl auto-detection failure in Binutils and GNU Make.
• Upgrade MinGW-w64 to 13.0.0.

15.1.0-r2

• Restore Windows NT 4.0 support.
• Fix libintl cache invalidation bug.
• Xmake is now moved to a separate package.

15.1.0-r1

• Upgrade MCF Gthread to 2.1-ga.1.
• Rewrite libintl for Windows to enable NLS for Binutils and GNU Make.
• The cross compiler is now organized by package.
• 7z archives are added back.
• The UTF-8 manifest is added to all executables (that target Windows Vista or later).
• Xmake is now moved away from the default prefix to lib/xmake. (It will be moved to a separate package in the future.)
