You want to specify the packages with the suffix ":i386" on them as you would a normal package, specifying the 32bit version.

Which packages are actually missing is more hit and miss, I'd start by installing the binutils and maybe see if the meta-pacakge build-essential:i386 pulls them all.

dpkg --print-foreign-architectures gives this output:
i386
so it looks like 32bit is enabled with multiarch.
How would I install the devel libraries for binutils and the build tools for 
32bit on my 64bit machine? I'm pretty new to all of this and have been learning 
everything along the way from various discussion boards etc.
Thanks!

Maybe just install the devel libraries for binutils and all the build
tools for 32bit.

It's probably not built for multi-arch, meaning if it insists on
building a 32bit module only, it likely won't work.  The whole
multi-arch thing made a mess for lazy 3rd party binary developers that
don't want to rewrite around compilation methodologies.

Hello,
I've been working on a MythTV on Mythbuntu project for a little while now and I've come to the step of setting up 
a serial ir blaster. My motherboard did not come with a serial port so I purchased an Iocrest  PCI-Express Multi 
I/O Controller serial card. I see the card when typing in "lspci" in a CLI. However, I've determined the 
card needs a driver, because when I put the command to find my ir blaster, "dmesg | grep tty" it oly 
comes up with "[    0.000000] console [tty0] enabled". When i plug the ir blaster into an older lubuntu 
computer I have I get "[    0.000000] console [tty0] enabled
[    1.029792] 00:08: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A". So it 
seems to find the blaster on the older computer, probably because the serial port is built into the 
motherboard. So, I found and downloaded the linux driver for the card that needs to be compiled. 
I've extracted the zip file the driver is in, navigate to the directory where the makefile is and 
then enter the command "make". I then get these errors: 
"hometheater@Hometheater:~/Downloads/Serial

Here is the makefile as well:

clean:

        rm -rf .tmp_version*"
Can anyone help me successfully compile this driver?
Thanks!
