how_to_install_zbarlight_on_windows.md

1. install zbar on windows with include and library files

2. make sure mingw installed and bin directory added to the path

3. in PYTHONPATH\Lib\distutils, create a file distutils.cfg and add two lines:

   [build]

   compiler=mingw32

4. get dll lib and include file from ftp://sourceware.org/pub/pthreads-win32/dll-latest copy files to PATH_MINGW32/[lib,bin,include] separately, just need file name like pthreadGC2 and remember to chang the name to libpthread

5. change or add lines in setup.py:

   extra_compile_args=['-std=c99', '-IPATH_TO\ZBar\include', '-lPATH_TO\ZBar\lib'],

   extra_link_args=["PATH_TO\ZBar\lib\libzbar.dll.a"],

   remove line libraries=['zbar'],

6. run python setup.py install

please note that you have to use doubled backslashes in step 5:
extra_compile_args=['-std=c99', '-IPATH_TO\ZBar\include', '-lPATH_TO\ZBar\lib'],
extra_link_args=["PATH_TO\ZBar\lib\libzbar.dll.a"],

For insurance purposes, yes. normally it's ok. @serg123e

Can you please rewrite those instructions? It's ununderstandable...

Yes, I am also having trouble understanding the instructions.
Can you re-explain step 4?

I am similarly having some issues following/understanding these instructions and get output that looks like this when I try to run the setup file:

any thoughts on what the issue might be?

wtf do I need to do on step 4?

how to step 4?

when i following these instructions i have the same problem as @mattm401
error: command 'c:\mingw\bin\gcc.exe' failed with exit status 1
so what should i do for this issue?

Can someone please clearly say me the steps to install " Zbarlight " in windows . Cause I'm trying it for long time but I can't able to fix it.

Can some one help me to install zbar light in windows ?

I got a working solution described here: https://medium.com/@ruvi.d/getting-zbarlight-to-work-on-windows-a3dc643dba18

@ruvi-d I created a whl file, then ran pip install zbarlight-3.1.dev0-cp38-cp38-win_amd64.whl, but when I add import zbarlight I get an error - ImportError: DLL load failed while importing _zbarlight: The specified module could not be found.
