django python-3.x xampp mod-wsgi apache2.4

I had apache 2.4 already installed with xampp.I tried adding mod_wsgi using the steps mentioned here

But when I add the line

LoadModule wsgi_module modules/mod_wsgi-py34-vc10.so

Apache does not start.

It is better to build mod_wsgi yourself from code rather than use an arbitrary binary off the net. The steps are as follows.

Ensure you have a decent Apache installation which includes header files, e.g. Apache 2.4.37 Win64 from Apache Lounge . Preferably installed at location of C:/Apache24.
Ensure your Python installation is set up so that you can pip install modules. This must include having the correct Microsoft C compiler needed by that Python version.
Run pip install mod_wsgi. If your Apache installation is not at C:/Apache24, then first set the environment variable MOD_WSGI_APACHE_ROOTDIR to its location. Ensure you specify path as C:/Apache24 form and not with back slashes, that is, not as C:\Apache24. This is only needed when doing the install, not later.
Run mod_wsgi-express module-config.
Copy the output from runing mod_wsgi-express module-config into your Apache configuration file.
Add configuration for a WSGI application to the Apache configuration.
Restart Apache and see if it works.

Note that you are better off starting with a WSGI hello world rather than some huge Django application when initially testing.

Thanks.I started learning Django instead.Using their server for now – Mika 7/3, 2017 at 13:44

When I run pip install mod_wsgi it fails with

c:\apache24\include\apr_network_io.h(29) : fatal error C1083: Cannot open include file: 'apr_perms_set.h': No such file or directory'.

This is with httpd 2.4.27. Any ideas how to fix that? – Inferno 13/8, 2017 at 16:11

The above attempt was with source I downloaded from http://mirrors.gigenet.com/apache/httpd/httpd-2.4.27.tar.gz. I just tried building with source cloned from github and that failed with c:\apache24\include\ap_hooks.h(39) : fatal error C1083: Cannot open include file: 'apr.h': No such file or directory – Inferno 13/8, 2017 at 16:42

I thought this was the same question, and I tried your solution and I had issues. That is why I asked in the comments. I will create a new question. – Inferno 13/8, 2017 at 20:45

"first set the environment variable MOD_WSGI_APACHE_ROOTDIR to its location". How is this done? – Luminous 23/8, 2017 at 1:28

That depends on what shell you are using on Windows. Have you looked up "How to set environment variable from shell in Windows"? – Bluster 23/8, 2017 at 1:47

in windows cmd setting the environment variable is done via set MOD_WSGI_APACHE_ROOTDIR=c:/path/to/apache Note that it will be unset as soon as you close the cms – Elijah 18/10, 2018 at 10:25

You might have to install visual studio build tools for this to work. These can be found on the visualstudio,microsoft.com/downloads under tools. In the following menue you have to choose cpp build tools and of those you only need the windows 10 sdk (around 4.5 GB) – Elijah 18/10, 2018 at 10:28

I've posted a question about the missing include files: #54268896 – Canaigre 19/1, 2019 at 15:3

Where to add the return of the mod_wsgi-express module-config cmd in the httpd.conf? Do I open a directory for this, or do I have to add it to some existing one in the file? The document doesnt clarify it. – Meghan 19/1, 2020 at 4:27

Use the release of Apache Lounge , if you still find c:\apache24\include\apr_network_io.h(29) : fatal error C1083: Cannot open include file: 'apr_perms_set.h': No such file or directory'. . This is best fit to Windows.

This topic is useful for Windows 10, xampp webserver as well.
I was struggling to find precompiled mod_wsgi.so for 
Apache/2.4.27 (Win32) 
Python/2.7.13 
This [link][1] is useful to find the appropriate version of mod_wsgi.
IF you are lucky, you can find the precompiled version [here][2]
There is a step by step guidance available [here][3]

The recommended method is to build it yourself using pip install mod_wsgi as explain in another answer. Grabbing arbitrary binaries is not guaranteed to work. You should build it for your specific Apache installation. – Bluster 15/9, 2017 at 13:41

lfd.uci.edu/~gohlke/pythonlibs saved me a lot of time getting the VC compiler toolchain on my machine. Basically pip install <.whl file>, then continue following the instructions here: github.com/GrahamDumpleton/mod_wsgi/blob/develop/win32/… – Sublease 4/8, 2018 at 9:56

@LarryMartell I met the same issue on windows and fixed it. You can try to copy file apr_perms_set.h from apr repository (https://github.com/traviscross/apr) to Apache2.4's include folder.

This doesn't answer the original question. Copying APR header files from a separate repo is also not guaranteed to work anyway if the issue was they were missing. Use a Apache distro which ships header files instead. If you aren't use the exact same header files as the Apache was compiled with, you can encounter problems. – Bluster 4/10, 2017 at 4:46

I am using a 64 bit operating system and have 64 bit python installed.

installing apache distribution for 64 bit OS from apachelounge https://www.apachelounge.com/download/ resolved the problem for me.

Yes, this is the only solution I've found so far. A question stays how to fix it for ApacheHaus: #54268896 – Canaigre 19/1, 2019 at 15:23
