Installation

The recommended way to install EvoDCinv is through pip (internet required):

pip install evodcinv

Otherwise, download and extract the package, then run:

python setup.py install

Troubleshooting on Windows

A Fortran compiler is required to install this package. While it is straightforward on Unix systems, it can be quite a pain on Windows. We recommend installing Anaconda that contains all the required packages to install FTeikPy on Windows systems.

1. Download MinGW 64 bits (choose x86_64-posix-sjlj) and extract the archive in your drive root.

2. Add MinGW to your system path:

   C:\<Your MinGW directory>\bin

3. Create the file distutils.cfg in <Your Python directory path>\Lib\distutils with the following content to use MinGW compiler:

[build]
compiler=mingw32

4. Open a terminal and install libpython:

conda install libpython

If you got the error:

Error: ValueError: Unknown MS Compiler version 1900

You may need to manually patch the file cygwinccompiler.py located in:

<Your Python directory path>\Lib\distutils

by replacing:

self.dll_libraries = get_msvcr()

in lines 157 and 318 by (be careful with indentation):

pass

You should also patch the file mingw32ccompiler.py located in:

<Your Python directory path>\Lib\site-packages\numpy\distutils

by commenting out from lines 96 to 104:

#        msvcr_success = build_msvcr_library()
#        msvcr_dbg_success = build_msvcr_library(debug=True)
#        if msvcr_success or msvcr_dbg_success:
#            # add preprocessor statement for using customized msvcr lib
#            self.define_macro('NPY_MINGW_USE_CUSTOM_MSVCR')
#
#        # Define the MSVC version as hint for MinGW
#        msvcr_version = '0x%03i0' % int(msvc_runtime_library().lstrip('msvcr'))
#        self.define_macro('__MSVCRT_VERSION__', msvcr_version)

If you got the error:

error: f90 not supported by GnuFCompiler needed for evodcinv/f90/dispcurve.f90

You may download the package and run the following command in the root directory:

python setup.py config_fc --fcompiler=gnu95 install
