I'm getting an error trying to run a program which uses the graph
unit:

Quote/usr/bin/ld: cannot find -lvga
The wiki says that this is because either libvga and/or the
development package isn't installed or the folder where it's installed
isn't in the linker path.

However I'm using Debian jessie and can't find any package similar to
"libvga" on my system or using apt-get. Any linux users out there have
any suggestions? Thanks.

Try to search for "svgalib".  That package installs libvga because of
some ancient compatibility reasons.

Can also be a CPU issue. It is not available for arm-linux and x86_64
linux only i386, afaik.

Check if the package graph is installed in
/usr/local/lib/fpc/<version>/units/<platform>

If it isn't then graph is not supported

In my case /usr/local/lib/fpc/3.1.1/units/arm-linux does not contain
graph because it is not supported on arm.

Thanks, I should have mentioned I'm using linux 32, and the graph unit
is in /usr/lib/fpc/3.0.0/units/i386-linux/graph.

I had no luck with using "svgalib" instead of "libvga".

seems indeed that svgalib is removed from debian after wheezy:
