[cfe-dev] build clang failed under MSYS (windows)

[asmwarrior]

Just for a record.
For those would like to build clang under 32bit MSYS and MINGW. I 
suggest you can do:

1, download a MSYS packge(which contain all the need tools) from:

http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/MSYS%20%2832-bit%29/MSYS-20101010.zip/download


2, download a MinGW package, I personal use Loaden's MinGW 4.4.5

http://code.google.com/p/qp-gcc/downloads/detail?name=mingw-static-4.4.5-all.7z&can=2&q=

But you can also use the Official mingw 4.4 or the TDM-MinGW 4.5.1

3, configure(edit) the file
      msys\etc\fstab

like: (my mingw was installed under d:/mingw)
d:/mingw /mingw
F:/cb/python27 /python

So that the MSYS system can find your MinGW compiler

4, download the llvm trunk and clang trunk.
and follow the steps like (the folder named "build" was along the llvm 
folder, the make option will build a release version, if you use the 
default option, the output file will eat 3G of your hard disk, but in 
release mode, it only eat 300M+)

cd build
../llvm/configure
make ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1


6, happy building

more reference can be found :

http://llvm.org/docs/GettingStarted.html#requirements
(I think the information about mingw can be updated, at least I use 
mingw 4.4.5)
