Additional dependencies for compiling from source:

## Installation flags¶

When installing Assimulo from source there are a number of available flags that can be specified in order to point to dependencies and which should be provided after the install command:

python setup.py install ...


The available flags are:

- "--sundials-home=..." - Point to an Sundials installation
- "--blas-home=..." - Point to an BLAS installation
- "--lapack-home=..." - Point to an LAPACK installation


Example:

python setup.py install --sundials-home=/home/chria/Sundials --blas-home=/home/chria/Blas


## Ubuntu¶

Once all the dependencies are satisfied an installation is done by:

python setup.py install


After a successful installation, the package will be located in Pythons dist-packages folder. Note, in case of 64bit systems the section troubleshooting see Troubleshooting should be consulted before installation.

Note

If Sundials has been installed on a different location then the default, use the sundials flag:

--sundials-home=/path/to/sundials


Note

To test Assimulo, go into the tests folder and type:

nosetests


Which requires python-nose.

## Windows¶

For installing on Windows it is recommended to download the binary installers from the Download page which includes all the solvers available. The below instructions are for installing Assimulo on Windows from source.

Note

Assimulo is also dependent on the Windows redistributable package for Windows.

Installing Sundials on Windows can be a bit tricky but here is a link for installing Sundials using cmake together with Visual Studio, http://sundials.wikidot.com/installation-cmake-vs . However I would recommend using Mingw instead of Visual Studio, here is link for installing Mingw on Windows and setting up Cython to use it, http://docs.cython.org/src/tutorial/appendix.html . If you would like to use Mingw instead of Visual Studio, just follow the above guide for installing Sundials until the step where Visual Studio is used. Instead of following those instructions, browse to Sundials build catalogue using the command prompt and type:

make
make install


Once Sundials and the rest of the packages are installed just install Assimulo by browsing to the folder in the command prompt and type:

python setup.py install --sundials-home=/path/to/sundials


After a successful installation, the package will be located in pythons dist-packages folder.

Note

To test Assimulo, go into the tests folder and type:

nosetests


Which requires python-nose.

## Troubleshooting¶

### Ubuntu 64bits¶

There have been some problems installing Assimulo on Ubuntu 64bits machines when Sundials has been installed with the default options. The problem generates the following error printout:

/usr/bin/ld: /home/chria/sundialscode/lib/libsundials_cvodes.a(cvodes.o): relocation R_X86_64_32
against .rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
