Fail to build octave with GCC 4.1.2

[Bo Yang-2]

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 \

The same thing happened to me in Ubuntu 9.04.  The problem is that the library
libg2c, which is needed by GNU Fortran 77 code, was not loaded or linked.

I loaded it with the Synaptic Package Manager, where the thing to load was
called libg2c0.   this then installed a link called  libg2c.so.0 to the loaded
library in /usr/lib

Then the problem of getting it to link.  I got it to work, but somebody should
install an option in the configure process for GNU Fortran that deals with this.

what I did was edit the Makeconf.in file where it had

FLIBS = @FLIBS@

to be

FLIBS = /usr/lib/libg2c.so.0 @FLIBS@

it would have been nice if     -lg2c    would have worked, but it didn't.
There is probably a better way to do this.   then    make clean     and  ./configure  and   make again.

After this fix, it got past building libcruft,  then bombed on trying to make (or remake) some documentation.
I don't know if that was caused by the    make clean     .

Anyway, after loading a few more things to deal with that, everything completed and it passed   make test
(as much as it is supposed to, given the current state of things).

Why don't you use gfortran instead of g77?

If you are using gfortran, then you shouldn't need g77 and libg2c.
