I installed the FC4 test 3 on my notebook. There's no octave package in FC4, and I try to compile one from source. The gcc version is 4.0. When make it, I get the following error: toplev.cc:485: error: trying to instantiate ‘template<class T> template<class U> octave_int::octave_int(U)’ toplev.cc:497: warning: missing sentinel in function call make[2]: *** [toplev.o] Error 1 make[2]: Leaving directory `/home/kenny/download/octave-2.1.70/src' make[1]: *** [src] Error 2 make[1]: Leaving directory `/home/kenny/download/octave-2.1.70' make: *** [all] Error 2 And the same errors occur in octave-2.1.69. Can anyone give a solution to it?
