gfortran mingw build script

Dear all,

I've finally found my mingw build scripts. Here is the description of  
how I make it work (I just rebuilt a new mingw system on a clean  
windows box in a few hours, so it's pretty straightforward).

 -- install a fully updated mingw system + MSYS system

 -- you need to download NSIS, "nullsoft scriptable install system",  
from http://nsis.sourceforge.net/ (any version will do) and install it  
in C:\Program Files\NSIS

 -- also install pthreads-win32: the three include files,  
pthreadGC2.dll and libpthreadGC2.a (which needs to be renamed into  
libpthread.a); they go into /mingw/include, /mingw/bin and /mingw/lib

 -- in my HOME, I create a gfortran directory, within which I put the  
build_gfortran script and the installer source file (gfortran.nsi)

 -- in $HOME/gfortran/, create a directory named dependencies that  
includes gmp and mpfr (headers in dependencies/include/ and libraries  
in dependencies/lib/); both libraries should be compiled with a  
specific build triplet to avoid excessive optimization (that would not  
allow other people to run your compiler): I use i586-pc-linux.

 -- in $HOME/gfortran/, put your source into a directory named gcc- 
trunk

 -- finally, create a directory $HOME/gfortran/mingw_to_include where  
you put all the files you want to have in your final package; usually  
I put there all the mingw include files (w32api), relevant binaries  
from /mingw/bin (binutils and other tools; you can rename mingw32- 
make.exe into make.exe), all object files from /mingw/lib and almost  
all static libraries from /mingw/lib (I just remove the GCC  
libraries). The exact list of files has changed over time (and  
requests by people), but for those interested, I am attaching the list  
of files in my "mingw_to_include" directory that I used for the last  
two years (the file is mingw_to_include.list).

 -- in mingw_to_include, I add a GPL.txt file and a README.html file  
that I wrote some time ago (with links to documentation, licences and  
other things). I am attaching the README.html file to this mail.


Once that is set up, all you should have to do is run "build_gfortran"  
and you'll get a gfortran-windows-YYYYMMDD.exe installer. The script  
even used to scp that installer to the server, but that is now bypassed.

Some comments on what I do:

 -- the script updates the SVN trunk everytime it is run
 -- I build for i586-pc-mingw32, because a) we want something that  
runs everywhere, and b) libgomp requires at least i586 to work (I  
think it is for TLS emulation)
 -- I currently use the latest mingw "candidate" binutils, but you  
can also compile something even more recent and install it system-wide  
(and in mingw_to_include)
 -- apparently, you need to configure with --disable-werror (due to  
PR38580), but that should only be temporary
 -- PDF documentation ("make pdf") currently doesn't work on my  
system, though I have no idea why (some strange message about  
unbalanced parentheses).
 -- I've never managed to get the testsuite running :(


Here you go, I hope it helps. Merry Christmas! (though a few days in  
advance)
