Compatible with Python>3.5 and Gfortran>=10. Some compiler switches used are not available in Gfortran < 10. It's been tested with Gfortran 10.0.1, 11.2, 11.3, and 12.2 and Python 3.6-3.11 on Mac M1, Linux RHEL7 x86_64, and Pop 22.04 x86_64.
If using Python from an Anaconda installation pay close attention to the GCC version printed out by Anaconda when you run Python. If it reports a GCC(7.3.0) then you will need to install a non-Anaconda python as your Anaconda Python is incompatible with the Gfortran required for Flora. The test described below will generate a segmentation violation if Anaconda and Gfortran are incompatible.
pip install forthon
python setup.py build install # if you have permissions to install python packages
python setup.py build install --user # to install in your user python area if you don't have needed permissions
$ python
>>>import flora
>>>flora.glr.glrgen()
To setup case set variables with:
from flora import glr
glr.varname1 = ....
glr.varname2 = ....
For a list of variables use
glr.varlist()
Because of the way the external objects are created a dir(glr) will not reveal the variable names.
There are a couple of cases in the examples directory. Run with:
python test1.py
python test2.py
Uncomment the call to plots1() for some graphics.
Compare with test1_ref.log and test2_ref.log. These logs are very old, compare for general agreement only.
