Installation/compilation problem on HP-UX 9.05

[Lane Yarrington]

I am trying to build octave on: HP-UX A.09.05 A 9000/735

I have gcc-2.6.3 and libg++-2.6 installed, etc.

The make goes fine until...

make[2]: Entering directory `/u6/hp/octave-1.1.1/src'

Since I don't know c++, I am stuck. Can anyone help me?
