Compiling a Driver for a PCI-e Serial Card

[Michael Butash]

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.

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 at Hometheater:~/Downloads/Serial Driver/MCS99XX/Linux/MCS9900_Cascade/MCS99XX-cascade_V_1.0.0.0$ make
