Re: [Discuss-gnuradio] working version of gnuradio for windows (mingw) available including audio-sink and wxgui

[Stephane Fillod]

Hi Martin,

Sorry for replying late on your exciting mail.
Did you get other feedback privately about it or about the Windows port?
I haven't seen much on my side.

No Cygwin? Good!

FYI, my cppunit windows patch has been accepted by the maintainers, 
I hope it will show up in the next official release.
I tried to convince the fftw maintainers about the patch, I'm not
sure I succeeded in. Besides, their release cycle is pretty long.

Now when boost will recognize gcc-4.x ?

Have you already submitted your patch to patch-gnuradio at gnu.org ?
Do you have any plan about it?

I've tested some bits of the patch, and IMHO, various parts need 
tweaks. For example the LIBGNURADIO_CORE_EXTRA_LDFLAGS is missing in 
the src/lib/Makefile.am, the new m4 are missing in config/Makefile.am,
gr_libgnuradio_core_extra_ldflags.m4 should check the compiler supports
the option. To me, the createfilemapping factory should check the second
mapping is contiguous to the first one, pretty much the same way
the Cygwin patch to the mmap_tmpfile factory does.

I have fixes in my tree for all the listed issues, and I can check
regression for Linux. Do you want me to submit them with you as credit,
or do you prefer that I send them directly to you?

That would be great to get all this stuff in the GNU Radio 2.6 release,
so it gets a better chance to be more widely tested.


Rem: so far, I only tested the MinGW cross-compilation, no run yet.

Thanks!

I've managed once to have the SIMD speedup working under Cygwin.
To get them into the CVS, I would need to rename all the files with
the .s (lowercase) extension to .S (uppercase). This way, I could use
the preprocessor to morph the .type statements to the appropriate
forms under Windows. Eric, would that be okay with you to delete/add
the .s/.S files ?

Having them in the wiki and a README allow easy copy/paste 8-)

Any plan on submitting it to patch-gnuradio at gnu.org ?
Eric, what's your position on this?

In the end, that'd be great to be able to produce an install wizard 
(thanks to Inno Setup (http://www.jrsoftware.org/isdl.php) of this binary 
distribution.  Bundling this distribution with USRP drivers, MinGW/MSYS, etc.
on a CDROM would make a perfect starter kit for the folks under Windows.
