Using RTEMS Source Builder in/for MinGW

[Kolja Waschk]

Hi,

I'm trying to build RTEMS tools for Blackfin to be used in Windows with 
MinGW. After unsuccessful first attempts to build them in real MinGW 
environment (more on that later), I succeeded with RSB on Ubuntu 13.10 
using --host=i686-w64-mingw32 and can use the results in real MinGW for 
building RTEMS.

There's only one small glitch: the automake is configured to use 
threads, but (at least in my MinGW environment) perl in MinGW is not 
configured to be used with threads. I have to manually patch 
Automake/Config.pm afterwards to have "perl_threads = 0" instead of 1.

How could I automate that, so that Config.pm in the tars built by RSB 
already have this change applied? Or should I split the process into 
steps -

  1. sb-set-builder with --no-install followed by
  2. patching Config.pm and
  3. another sb-set-builder start with --bset-tar-file?

The build in real MinGW failed at first because during automake build 
some directories ("ae2") were not created or not found. I'll have a look 
into that later, or are there known big problems that prevent successful 
use of RSB in MinGW anyway?

I'm using RSB as of 2013-09-15, currently; and for several reasons, in 
my MinGW the default host gcc is an old gcc 4.6. But I doubt that it is 
a problem for the automake tool build.
