The last post looking at using the Python F2Py package said:
It is also necessary to install a Fortran compiler. After some trial and error I found that the MinGW (Minimalist GNU for Windows) package worked well.
Trying some simple examples on a new computer however yielded a variety of “unable to find” errors, and a search on each returned a range of conflicting suggestions on how they might be fixed. Eventually the following (relatively straightforward) process worked for me:
- Uninstall Python and install the latest version of Anaconda Python, appropriate to the operating system. I actually had 2 versions of 32 bit Python in different folders, on 64 bit Windows, which may or may not have contributed to the problems.
- Install the version of MinGW provided with the Anaconda download, from the command line using:
conda install mingw
from the top level Anaconda folder. There is an installation package available on the MinGW site, but I couldn’t get F2Py to work with that installation.
- That’s all
I had previously installed Visual Studio Express 2015. It is not clear to me whether this is required or not.
After this process I found that:
- The simple examples from the F2Py tutorial worked without a problem.
- Any example with a PRINT* statement in the Fortran code still does not compile. I haven’t found a solution to this one yet, other than avoiding PRINT statements.
- The callback example from the tutorial worked after adding a line to declare the FUN variable as REAL*8. More on this one later.
I hope to have some more detailed and useful examples to present in the near future!
