[R-SIG-Mac]ggobi and Mac OS X

[Dennis A. Wolf]

Greetings:

I have been trying to install ggobi with the ultimate goal of using it 
within R. I am having difficulty which appears to be related to gcc not 
allowing -shared as an option with Mac OS X. Can anyone suggest how I 
can overcome this problem?

I am using a 15" flat-panel iMac, Mac OSX 10.2.4, Apple's X11 beta 3.

The gory details of the attempted installation follow:

I downloaded ggobi, ggobi_0.99-10.tar.gz and gunzipped and tarred it as 
su to get the directory /usr/local/lib/ggobi and within that directory 
I did

sudo ./configure --with-xml --enable-embed

and got:

Now when I

sudo make

I got

It appears that gcc does not like the -shared option. And indeed in the 
help file for gcc it says that this option is not allowed for Mac OS X.
