Hi all, 

I am trying to configuring octave source (3.6.4) on Maverick and have faced several issue. 
Now, I need some help. 

my current problem is 
while ./configure is working, preprocessor is rejecting some headers and I can't figure out why. 
(actually I run './configure CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib'
because, without flags, configuration process reported that it couldn't find where the headers were.)

I checked the header files are located properly under /usr/local/include.

The error message was as follow.

I am not familiar with your system. But generally it is important to see config.log to clarify what is wrong.

BTW, octave-3.6.4 is no longer maintained. Your post is suitable to help mailing list.
The maintainer list is the place to discuss current and developers  version.

Hi Tatsuro, 

I just figured out that this kind of problems are occurred when proper libraries were not installed on the system. 
Right after I installed all libraries and pkgs mentioned in http://www.pt.xemacs.org/wiki.pl?OctaveForMac, configuring worked fine! 

I am a newbie in octave contribution, so I just found out there is another help mailing list and 
now I am working on the sources from repo. 
Anyway, thanks for your kind reply.

John
