Thanks. I was able to get the Maxima software to run on my Zaurus SL-C760 with the Sharp ROM.
I also get the message about the PC symbol, but I am still able to use Maxima.
For the benefit of people who are less familiar with Linux, I used Cygwin on my Windows computer to extract the archived Maxima files:
gzip -d /cygdrive/c/maxima.tar.gz
tar xvf /cygdrive/c/maxima.tar
I installed the maxima directory on my SD card:
/mnt/card/maxima
You would replace, "/mnt/card", with, "/mnt/cf", if you have the maxima directory on your compact flash card.
I then created a symbolic link to that directory:
su root
cd /usr/local
ln -s /mnt/card/maxima .
exit
You can add the following line to your .bashrc file:
export PATH=$PATH:/usr/local/maxima/bin
You can do that with a text editor or by typing at the command line:
echo "export PATH=$PATH:/usr/local/maxima/bin" >> .bashrc
The next time that you exit and return to the Terminal application, just type, "maxima", to start the program.
The easiest Maxima documentation to use on the Zaurus is the HTML documentation:
/usr/local/maxima/share/maxima/5.9.1/doc/html/maxima_toc.html
Just create a bookmark to that file, and you can view the Maxima documentation in your web browser, such as NetFront or Opera. You can also free up some disk space by deleting the documentation that is in the formats that you cannot read or do not use on the Zaurus in the doc directory.
