Re: [Bug-datamash] Windows Build Instructions - MinGW x64 or i686

[Clifford Sobchuk]

Hi Asaf, There is a very large selection of different versions of the 
development packages on Cygwin that would impact having a repeatable setup. For 
example - there are 12 different versions of automake alone. Could you provide 
me a listing of what you have installed for the windows development 
environment. 
Thanks,

When I build windows binaries, I use a Windows Server 2012 with cygwin version 
2.5.1, with gcc 5.3.0 and/or MinGW-gcc 4.9.2 .
I use the latest official tarball (currently datamash version 1.1.0).

The following commands will demonstrate (these are executed inside the cygwin 
shell terminal window):

    $ uname -a
    CYGWIN_NT-6.2 WIN-9FFSHRJAFVN 2.5.1(0.297/5/3) 2016-04-21 22:14 x86_64 
Cygwin

    $ echo `cmd /c ver`
    Microsoft Windows [Version 6.2.9200]

    $ gcc --version
    gcc (GCC) 5.3.0

    $ x86_64-w64-mingw32-gcc --version
    x86_64-w64-mingw32-gcc (GCC) 4.9.2

    $ i686-w64-mingw32-gcc --version
    i686-w64-mingw32-gcc (GCC) 4.9.2

    $ wget http://ftp.gnu.org/gnu/datamash/datamash-1.1.0.tar.gz
    $ tar -xf datamash-1.1.0.tar.gz
    $ cd datamash-1.1.0

Build for cygwin (will require cygwin's dlls):

    $ ./configure
    $ make

Build native windows exe (64bit):

    $ ./configure --host=x86_64-w64-mingw32 --disable-nls
    $ make

Build native windows exe (32bit):

    $ ./configure --host=i686-w64-mingw32 --disable-nls
    $ make


On a somewhat-related note, it was brought to my attention in a recent thread ( 
http://lists.gnu.org/archive/html/bug-datamash/2016-06/msg00002.html ) that 
datamash's exe files respect the current locale (as they should), but on 
windows it's hard to force a different locale (unlike on unix, where LC_ALL=C 
solves the issue).
As a temporary work-around, I've updated the file 'src/datamash.c" to always 
use simple "C" locale (mainly: use dot character as decimal separator), by 
changing line 1069 from:
   setlocale(LC_ALL,"")
to:
   setlocale(LC_ALL,"C")

I will soon fix this issue in the git repository, but at the moment it's done 
manually before building a windows binary.

Hope this helps,
regards,
