Running make errors and doesn't work

[undefined06855]

If I run make the following happens:

make -C "/lib/modules/"5.19.0-41-generic"/build" M=/home/undefined0/projects/cameras/surface-ipu3-cameras modules
make[1]: Entering directory '/usr/src/linux-headers-5.19.0-41-generic'

And if I run sudo make instead (Didn't think this would do anything, really)

Are there some dependencies or something I've missed out?

[undefined06855]

I installed a couple of packages I think it needed, flex and bison, and sudo make gives this error instead:

make -C "/lib/modules/"5.19.0-41-generic"/build" M= modules
