Due to some reasons one may need to rebuild MSYS binaries.
But finding instructions how to do this was not so straightforward.
After fiddling a while we could get msysCORE recompiled, with
the following procedure:
1) Downloaded mingw-get-0.2-mingw32-alpha-3-bin.zip from
2) Created C:\MsysReComp
3) Unzipped (using some tool) mingw-get-0.2-mingw32-alpha-3-bin.zip there
4) Started windows command prompt (which is used in 5 and 6 below)
5) cd:d to C:\MsysReComp and executed:
bin\mingw-get install gcc g++
bin\mingw-get install msys-dvlpr
7) In terminal window started by msys.bat MSYS entered:
tar Jxf /path/to/msysCORE-1.0.16-1-msys-1.0.16-src.tar.lzma
and then entered ./msysrlsbld
That was enough to do msysCORE (or at least we think so). Doing other
builds the first thing to add was msys-patch...
The point of this excercise was to create a 'standalone' MSYS building
environment, which can be deleted after use (or archived for future use).
I hope this is useful to others too and thank all of you for creating
the software to make this possible.
And if you know anything to make this even easier please tell us.
