Hello, All,

I have gotten xlinrad to compile and run with a 64 bit version of Ubuntu. I have not gotten it to work in I/Q mode yet, and haven't checked it for bugs while running yet.

I have not tried to get the svgalib version of linrad to run yet.

The steps I used to get this far [get xlinrad to compile and start running] include [all listed here so to make it easier to find in the future]:

sudo apt-get install ia32-libs ia32-libs-gtk ia32-libs-sdl ia32-libs-kde [all may not be necessary]

sudo apt-get install libc6-i386
sudo apt-get install libc6-dev-i386
sudo apt-get install libfreetype6.dev [I suspect this is unnecessary]
sudo apt-get install fontforge [I suspect this is unnecessary]

cd /usr/lib32
sudo ln -s libX11.so.6 libX11.so
sudo ln -s libXext.so.6 libXext.so
sudo ln -s libfreetype.so.6 libfreetype.so [I suspect this is unnecessary]
sudo ln -s libz.so.1 libz.so

add lines:
'/usr/lib32'
'/lib32'
to the /etc/ld.so.conf file and then
run 'ldconfig'

Modify the Makefile.in file in the Linrad directory by adding '-m32' in 4 places: after the = sign on the two lines near the beginning of the file starting with CFL and CFW, and after the 'gcc' in two lines beginning with 'gcc' later in the file.

Then do the usual
cd /linrad/linrad-02.17 [or whatever]
./configure
make xlinrad
./xlinrad

This runs for me...how well I will determine over the next few days.

This is using, as previously noted, Linux w3sz-amd64 2.6.15-27-amd64-generic #1 SMP PREEMPT Sat Sep 16 01:50:50 UTC 2006 x86_64 GNU/Linux

and

gcc -v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,java,f95,objc,ada,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.0 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-java-awt=gtk-default
--enable-gtk-cairo
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-4.0-1.4.2.0/jre
--enable-mpfr --disable-werror --enable-checking=release
x86_64-linux-gnu
Thread model: posix
gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

Alsa sound.

At this point xlinrad works with these soundcard settings:

works with Realtek [63] as R/W, 'normal receiver' [choice 1, not I/Q]

works with Delta44 [01] as input, Realtek [63] as output, 'normal receiver' [choice 1, not I/Q]

Hope that helps Ernst and others wanting to move forward in this regard. I apologize in advance for anything/everything that is extraneous or less than elegant in this prescription.

Another option is to set up an IA32 chroot and compile and run Linrad from there. That is more involved and I would reserve that option for a persistent failure of the type of option outlined above. https://alioth.debian.org/docman/view.php/30192/21 would give you a general roadmap of how to pursue this option.
