Missing soft link to linux source tree - linux

Question

In /lib/modules/xx.xx.xx-xx there is supposed to be two soft links one called source and one called build. The source one is there and its fine but the build one is missing and I have no idea where it is supposed to point to and I need to install a driver for my video card. Is there any way to find out where that is supposed to point if so how and where. I know there are a lot of other questions out there but not of them actually discribe where they are supposed to be pointing in the end.
Updated the link and now it is having build errors that I can't fix because I can't even find the struct its talking about

I copied it from the disk because it was a read only and placed it into my home directory.
I feel like this has become a whole new issues or possibly the link is wrong and is causing this issue.

this is mine:

actually it's managed by package manager. I install linux headers using apt-get. I think you should do the same, unless you are advanced kernel developer.
