Question

I downloaded the latest source of mod_wsgi from https://code.google.com/p/modwsgi/source/checkout, but I can’t compile it in Windows with Apache 2.2 & Python 3.2. There are some undefined variables because MOD_WSGI_WITH_DAEMONS is undefined; MOD_WSGI_WITH_DAEMONS is undefined because APR_HAS_FORK is 0.

In “mod_wsgi.c”:

#if APR_HAS_OTHER_CHILD && APR_HAS_THREADS && APR_HAS_FORK
#define MOD_WSGI_WITH_DAEMONS 1
#endif
...
#if defined(MOD_WSGI_WITH_DAEMONS)
...
static WSGIDaemonProcess *wsgi_daemon_process = NULL;
...
#endif

In “apr.h”:

#define APR_HAS_FORK              0

Is there any chance I compile mod_wsgi with Apache 2.2 & Python 3.2 for Windows? If so, how?

Update:

In the default branch, in “wsgi_apache.h”:

#if (APR_MAJOR_VERSION == 0) && \
    (APR_MINOR_VERSION == 9) && \
    (APR_PATCH_VERSION < 5)
extern apr_status_t wsgi_apr_unix_file_cleanup(void *);
extern apr_status_t wsgi_apr_os_pipe_put_ex(apr_file_t **, apr_os_file_t *,
                                            int, apr_pool_t *);
#define apr_unix_file_cleanup wsgi_apr_unix_file_cleanup
#define apr_os_pipe_put_ex wsgi_apr_os_pipe_put_ex
#endif

But in “apr_version.h”:

#define APR_MAJOR_VERSION       1
...
#define APR_MINOR_VERSION       4
...
#define APR_PATCH_VERSION       5

So apr_unix_file_cleanup will not be defined.

I am using Apache 2.2.22 and Python 3.2.3 in Windows 7 (x64).

The latest mod_wsgi-3.X can be compiled to an “.so” file, but got this error:

mod_wsgi.so.manifest : general error c1010070: Failed to load and parse the manifest. The system cannot find the file specified.

I am worried about this. I don’t know if this is a real problem.

And also, I can’t load mod_wsgi module. The Apache’s error log says:

Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding: cp0
[Sat May 05 18:35:43 2012] [crit] (OS 1813)The specified resource type cannot be found in the image file.  : master_main: create child process failed. Exiting.

I found this: http://bugs.python.org/review/6501/diff/2518/6050. It may cause the issue. I’m not sure.

Answer 1

Try again with the very latest source code. You may also want to use the 3.X branch instead of default branch for time being.
