Using Symbolic Package in Octave
[edit | edit source]- Visit http://octave.sourceforge.net/index.html
- Download symbolic-1.0.9.tar.gz
- In Ubuntu, using the Ubuntu Software Center, I installed GiNac and CLN related software and symbolic package for Octave. But it did not properly installed.
- After extracting files from symbolic-1.0.9.tar.gz, I followed the following steps.
./configure ./make ./make INSTALL_PATH=/usr/share/octave/packages/3.2/symbolic-1.0.9
- While doing this, I got an error message related to mkoctfile. So, I used the following command: sudo apt-get install ocatve3.2-headers. Then I was able to install the symbolic packages in the Ubuntu.
