Re: Problem installing Octave on Mac OS 10.2

[Per Persson]

Andri,
how did you install g77? I installed it via fink and did have a similar 
problem and got around it by setting FLIBS explicitly before running 
configure (see below from discussion on fink list). In your case you'd 
probably want just '-L/usr/lib/gcc/darwin -lg2c' or possibly just -lg2c 
(no need to specify -lm on OS X, but it doesn't hurt either). I don't 
know what is causing this, it could be a problem with g77 
configuration(???).

BTW, if you are using the CVS version of octave, you'll need to work 
around a (known and reported) bug (sigh...) in Apple's gcc by commenting 
out every instance of '#pragma interface'.... or alternatively try using 
-fno-rtti when compiling (it won't get you all the way though:-( )
There are a few more quirks, but a lot less than there used to be:-)

HTH,
Per
