Re: [Iaxclient-devel] Compiling with MinGW/Cygwin and Win32 Latency

[Darren S. <da...@ba...>]

Hi all

I found when i installed wxwindows, i had to use --enable-debug as well =
on the commandline as well as the --disable-shared i think it was, to =
force it to create a static library.

It'll then create a debug .a file in the wxwindows/lib dir =
libwxs<something>d-4.2.0.a , can't remember the exact filename (i'm 120 =
miles from my pc at home atm) anyway, i had to rename it to remove the =
-4.2.0 bit for it to work.

Also, when you set the WXWIN variable, use =
/c:/<windows-path-to-wxwindows-dir> instead of the cygwin path, as mingw =
wont be able to find it.

PS. Great work on the winiax client Faizan, looks nice in the quick test =
i gave it from my laptop :-)

Best Regards

    Right on!  My next step is to install wxwindows from =
www.wxwindows.org as per your instructions with MinGW.  I think I am =
going to call it a day but either tomorrow or Saturday I will get to it.
    I am also going to play with the settings in portaudio and will let =
the list know what worked for me.  I will document the steps to get =
everything up and running on a Windows XP environment so we can put it =
in a README-WIN.txt file.
    Thank you for your invaluable support, without you I would have not =
made it this far.=20


  Great!  I'm glad I could help, and I'm glad you stuck it out.

  While I think it's a bit harder to get set up with MinGW and =
wxwindows, that it would be to use VC (once Faizan's project files are =
in place, etc), I think it's better, because then changes and =
contributions you make are helpful for people on platforms other than =
Windows.

  Bill still doesn't have 100% of the market yet!

        It is now working with the "make" from Cygwin.  I had to =
download it from http://cygwin.com/setup.exe as it is not part of the =
default install.
        I was able to compile with "make clena" followed by "make" under =
iaxclient/simpleclient/testcall.  It works and I tested it and modified =
it to use my own *.  There was quite a bit of noise and quite a bit of =
delay but it is very promissing.=20

      Cool.  I'm glad you got it working.  I guess I installed cygwin a =
long time ago, and I probably did install more than the default install, =
so we should note this in the README with the sources.

      Thanks for sticking in there!

      The latency can be adjusted somewhat by setting an environment =
variable, PA_MIN_LATENCY_MSEC  It defaults to 200ms for Win9x, and 400ms =
for NT.  Try setting it to something smaller, and it might work for you. =
 Some people have tried setting this to 50ms or so, with success, but it =
depends on your system.

      The portaudio people set this by default pretty high on windows, =
because windows has pretty bad real-time support.  It's better, by =
default, on Linux/MacOSX.

      All of this is really in the portaudio library code, so if you're =
looking to change things or research them, look in the portaudio =
directory, and/or the portaudio website and mailing lists -- there's =
lots of info on it there, and I think they're improving things for their =
next release.



        Then I got ambitious and tried the same steps undex =
iaxclient/simpleclient/wx.  I watched in horror the screen go for quite =
a while.  Then it stopped with a message "1 error in wx.o".  I tried to =
redirect the output to file so I could attach it here but only got the =
first few lines of the "Makefile" execution.  Then, when the Cygwin make =
takes over, it all went back to the STD output, my screen.
        Since I made it this far, I am now more committed than ever.
        Did I miss a step to compile the "GUI" version?=20

      And if you thought getting the environment setup for compiling =
"testcall" was complicated, wait till you try compiling with wxwindows =
:)  (OK, it's not _too_ bad, really.  Several people besides me have =
done this already).

      Basically, what you need to do is get wxwindows from =
wxwindows.org, compile that with mingw (when you do this, make sure you =
compile it to make _static libraries_, not DLLs), and then if you have =
the WXWIN environment variable set properly, the build of wx will =
succeed.

      The errors you got are all probably because you don't have wxwin =
installed/compiled, so it can't find the wxwin headers, and then the =
compiler can't make sense out of the rest of the code.
