Fail to build octave with GCC 4.1.2

[Bo Yang]

Hi,
   I am a new comer to Octave, after some google search, I didn't find the simple error for my compiling errors. 
My environment:
GCC 4.1.2 

And the errors are:

/usr/bin/g++  -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -DHAVE_CONFIG_H -mieee-fp -Wall -W -Wshadow -Wold-style-cast -g -O2 -rdynamic \
        -L..  -fPIC  -o octave \
        main.o  \

        -loctinterp -loctave  -lcruft   \
             \
            \

Could you please help me on this? Thanks!
