dmtx-wrappers

Visual Studio solution for 32-bit and 64-bit builds of the pydmtx Python package. Tested with Anaconda distribution of Python 2.7.x and Visual Studio Community 2013.

Forked from http://sourceforge.net/p/libdmtx/libdmtx/ci/master/tree/ on 2015-04-03.

Installing on Windows

Install a release from this repo. For 32-bit:

https://github.com/NaturalHistoryMuseum/dmtx-wrappers/releases/download/v0.7.4b1/pydmtx-0.7.4b1-cp27-none-win32.whl

64-bit:

https://github.com/NaturalHistoryMuseum/dmtx-wrappers/releases/download/v0.7.4b1/pydmtx-0.7.4b1-cp27-none-win_amd64.whl

The wheel was built using Visual C++ 2013. If Python reports an ImportError when import pydmtx is run then you will need to install the Visual C++ Redistributable Packages for Visual Studio 2013.

Building

You should only need to build if you want to release a new version.

pydmtx can be built using MinGW but I had limited success with that solution - the 32-bit build was able to find barcodes in some images but not all and the 64-bit build caused the Python process to segfault as soon as a _pydmtx function was called. 64-bit builds of MinGW are known to be buggy.

This Visual Studio project was created by following Python's instructions for Building C and C++ Extensions on Windows and instructions on libdmtx wiki.

  • Install Visual C++ 2013 Community Edition

  • Build the 32-bit and/or 64-bit Release target of libdmtx-windows

  • Install the current Python 2.7 release of Anaconda

  • Build the pydmtx Python extension module and a wheel:

    cd dmtx-wrappers\pydmtx
pip install --upgrade pip
pip install --upgrade setuptools
pip install wheel
build.bat
