ZBar is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.The purpose of this repositoryThis repository is forked from the ZBar python wrapper download at PyPI, and only contains the python wrapper for the C library. For the full C library source, installation directions, etc., check out the ZBar homepage.The Natural History Museum's fork adds a wheel build for Windows 32-bit.Fixes implementedPatches imagescanner.c to fix crashing (segmentation fault 11) issues with import zbar on OS X.Patch taken from on Mac OS XInstall zbar using homebrew:Install the extension modulepip install on Windows 32-bitInstall a release from this repo, e.g.:pip install for Windows 32-bitYou should only need to build if you want to release a new version.Download and installMiniconda-latest-Windows-x86.exe.DownloadMinGW,install to C:\MinGW, and runc:\MinGW\bin\mingw-get.exe install gccCreate libpython27.a from python27.dll, for the benefit of the MinGW linkerFollowing this advice. python27.defc:\MinGW\bin\dlltool --dllname python27.dll --def python27.def --output-lib libs\libpython27.a">c:\MinGW\bin\mingw-get install pexportsFOR /F %a IN ('python -c "import sys; print(sys.exec_prefix)"') DO cd %ac:\MinGW\bin\pexports.exe python27.dll > python27.defc:\MinGW\bin\dlltool --dllname python27.dll --def python27.def --output-lib libs\libpython27.aDownloadzbar-0.10-setup.exeand install to c:\zbarBuild the zbar Python extension module and a wheelSET PATH=c:\MinGW\bin;%PATH%SET INCLUDE=C:\ZBar\include;%INCLUDE%SET LIB=C:\ZBar\lib;%LIB%SET LIBPATH=C:\ZBar\lib;%LIBPATH%SET PATH=c:\MinGW\bin;%PATH%build.bat">cd SET PATH=c:\MinGW\bin;%PATH%SET INCLUDE=C:\ZBar\include;%INCLUDE%SET LIB=C:\ZBar\lib;%LIB%SET LIBPATH=C:\ZBar\lib;%LIBPATH%SET PATH=c:\MinGW\bin;%PATH%build.batThe dist directory will contain a wheel.

MinGWMinGW is a native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications. It includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platform.MinGW provides you with a minimalist development environment and a complete Open Source programming tool set, which is suitable for the development of native MS-Windows applications, which do not depend on any 3rd-party C-Runtime DLLs*. Key features of MinGW include:A port of the GNU Compiler Collection (GCC), including C, C++, ADA and Fortran compilers.GNU Binutils for Windows (assembler, linker, archive manager).A command-line installer, with optional GUI front-end, (mingw-get) for MinGW and MSYS deployment on MS-Windows.A GUI first-time setup tool (mingw-get-setup), to get you up and running with mingw-get.MinGW compilers provide access to the functionality of the Microsoft C runtime, and some language-specific runtimes. It is worth noting that MinGW, being minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows. If you need POSIX application deployment on this platform, please consider Cygwin instead.*It does depend on a number of DLLs provided by Microsoft themselves, as components of the operating system; most notable among these is MSVCRT.DLL, the Microsoft C runtime library. Additionally, threaded applications must ship with a freely distributable thread support DLL, provided as part of MinGW itself.

Vs-wsl-fortranA Fortran example project using Visual Studio and Windows Subsystem for Linux (WSL).Getting startedRequirementsVisual Studio 2019Windows Subsystem for Linux (WSL)Note: This was tested on a system with Windows 10 2004, Visual Studio 16.6 and WSL 2.Prepare the WSLDownload and install a Linux distribution for WSL.This example was tested with Debian Buster, but other distributions should work just as well.Install the packages needed for your WSL installation to work with Visual Studio:sudo apt install g++ gdb make ninja-build rsync zipFor more detailed instructions see theLinux development with C++ documentation.In addition we need to install the gfortran compiler:sudo apt install gfortranBuild the projectStart Visual Studio and open the vs-wsl-fortran folder.Select the WSL-GCC-Debug target, then build it.Run the Linux executable inside Visual StudioSelect vs-wsl-fortran (src\vs-wsl-fortran) as the startup item and start it (F5).To see the output you might need to open the Linux Console Window view.Cross-compile a Windows executableThe mingw compiler can be used to create Windows binaries.Install an appropriate mingw package in the WSL installation, for example:sudo aptitude install gfortran-mingw-w64-x86-64Build the project for WindowsIn Visual Studio select the WSL-MINGW-Release target and build it.After building the executable you still need to copy some DLLs into that folder.In the case of Debian these DLLs are provided by the mingw package:/out/build/WSL-MINGW-Release/srccp /usr/lib/gcc/x86_64-w64-mingw32/8.3-win32/*.dll .">cd vs-wsl-fortran_folder>/out/build/WSL-MINGW-Release/srccp /usr/lib/gcc/x86_64-w64-mingw32/8.3-win32/*.dll .Now you can run the executable in a Windows PowerShell or CMD:NotesCMakeSettings.jsonNinja is not yet supported for Fortran, so generator has to be set to "Unix Makefiles" instead.When cross compiling the compiler has to be specified with "-DCMAKE_Fortran_COMPILER=/usr/bin/x86_64-w64-mingw32-gfortran" in the CMake Command Arguments.This is not necessary when targeting Linux, in that case the default gfortran compiler is detected automatically.Fortran syntax highlighting in Visual StudioBy default Visual Studio does not provide any syntax highlighting for Fortran code,but it can be added as described here.First create the following folder:%userprofile%\.vs\Extensions\Syntaxes\Then download an appropriate

Cygwin: Cygwin proporciona una capa de compatibilidad con UNIX en Windows y ofrece una amplia gama de herramientas y utilidades de software de código abierto, incluido GCC. Puedes descargar el instalador de Cygwin desde su sitio web oficial: Durante la instalación de Cygwin, asegúrate de seleccionar los paquetes relacionados con GCC, como "gcc-core" y "gcc-g++", para instalar el compilador de C y C++ respectivamente. MinGW (Minimalist GNU for Windows): MinGW proporciona un conjunto de herramientas de desarrollo de software de GNU, incluido GCC, para Windows. A diferencia de Cygwin, MinGW se enfoca en proporcionar una capa de compatibilidad mínima con UNIX y no requiere una capa de emulación adicional. Puedes descargar MinGW desde su sitio web oficial: (Minimal SYStem 2): MSYS2 es una distribución de software independiente basada en Cygwin y proporciona una plataforma similar a UNIX en Windows. Incluye una amplia gama de herramientas de desarrollo, incluido GCC. MSYS2 ofrece un sistema de gestión de paquetes para facilitar la instalación y actualización de software. Puedes obtener MSYS2 desde su sitio web oficial: (Windows Subsystem for Linux): WSL permite ejecutar un entorno Linux completo en Windows. Con WSL instalado, puedes acceder a una distribución de Linux, como Ubuntu, dentro de Windows. Esto te brinda la capacidad de instalar GCC y otras herramientas de desarrollo directamente desde la distribución de Linux. Puedes habilitar WSL en Windows siguiendo las instrucciones en la documentación oficial de Microsoft:
