Hi everyone,
I completed my first good GCC build with mingw-w64. It uses GCC 4.5.2,
binutils 2.20.51 and mingw-w64 snapshots from 2010-09-16. The script used to
build the binary package is included in the source download. It has been
used successfully on MSYS.
Some special properties about this build:
- For now, only x64 (x86 is building now).
- It is an optimized build tuned for Intel's core2 architecture
(-mtune=core2) + other optimizations which improve performance substantially
- It has Graphite and lto optimization capabilities. See the GCC docs for
the what and how.
- It includes the full mingw-w64 package, including ddk and directx headers
and libraries.
- Although the Readme.txt says multilib, it is not. The x64 versions
targets x64 Windows, the soon to be uploaded x86 version targets x86
Windows.
- The source file contains the full sources to everything used, with
patches.
- Only two patches have been applied: one for pthreads-win32, one for
cloog-ppl's configure script to allow ppl-0.11.
Important: the binary packages need to have three headers deleted:
lib/gcc/x86_64-w64-mingw32/4.5.2/include/ stdarg.h, stddef.h and float.h.
This is important for projects using win32 float.h functionality, eg Qt.
If you find any problems, please let me know.
Ruben
