Not true.

there are default limits, which a user can change, and hard limits,
which a user cannot change.  If you increase the default limits
with ulimit to the hard limits, then that's almost always enough
to actually compile stuff like qt and... uh.. I forget the other
one.

Again, read the ulimit man page, and search for 'ulimit', and
actually read what it says.  This is all explained.
