Hi Graham,

Is there a specific method to install mod_wsgi for Python 3.7 ?

We are trying to install using command 
pip install mod-wsgi
or
pip3.7 install mod-wsgi

But installation fails with gcc error. Gcc has been installed though.

Any idea any step we are missing ?

Operating System is centos 7

Thanks

What was the error?

You need to have the relevant python devel and Apache httpd devel packages installed as well. Do you have them installed?

The need for these to be installed in mentioned in:

Hi Graham,

Thanks for the quick response.

python-devel and httpd-devel is installed.

Message for yum install httpd-devel
Package httpd-devel-2.4.6-89.el7.centos.x86_64 already installed and latest version

Message for pip3.7 install httpd-devel
Collecting httpd-devel
  Could not find a version that satisfies the requirement httpd-devel (from versions: )
No matching distribution found for httpd-devel

Message for yum install python-devel
Package python-devel-2.7.5-80.el7_6.x86_64 already installed and latest version

Message for pip3.7 install python-devel
Collecting python-devel
  Could not find a version that satisfies the requirement python-devel (from versions: )
No matching distribution found for python-devel

I think the issue is due to the python-devel is being installed for ver 2.7

Not able to figure out the correct packages that are to be installed.


Regards

Mahesh

You still didn’t show the error messages you got when trying to pip install mod_wsgi.

I need to see what was at:

That was the real error message.

If necessary run pip with the -v option to show verbose output.

Hello, I recently did an installation on centos7, follow the steps.

yum install mod_wsgi
Download git latest version https://github.com/GrahamDumpleton/mod_wsgi/releases
tar xvfz x.x.x-X.Y.tar.gz
cd x.x.x
./configure --with-apxs = /usr/bin/apxs --with-python=/usr/local/bin/python3.7
make
make install

you can use a find apxs to know the location of the file.

I hope it helps.

Hi Anderson,

Thanks for your suggestion.
I tried the sequence but getting error as below:
for make command.
collect2: error: ld returned 1 exit status
apxs:Error: Command failed with rc=65536

I have another question ?
Did you install python-devel for Python 3.7 ?
If installed what was the command ?

Regards

Mahesh

As I already pointed out, that part of the error message says nothing, it is just the result status.

It is all the messages before that which are the important bit. Is there a reason you can't supply them as already asked?

Hello Mahesh, yes this installed python-devel.

What are you installing so much? What is the senary?

This issue is documented in:


It is because your Python installation wasn't installed with a shared library. The warning at the top even tells you this:

    WARNING: The Python installation you are using does not appear to have
    been installed with a shared library, or in the case of MacOS X, as a
    framework. Where these are not present, the compilation of mod_wsgi may
    fail, or if it does succeed, will result in extra memory being used by
    all processes at run time as a result of the static library needing to
    be loaded in its entirety to every process. It is highly recommended
    that you reinstall the Python installation being used from source code,
    supplying the '--enable-shared' option to the 'configure' script when
    configuring the source code prior to building and installing it.

You will need to reinstall your Python from fresh source code with shared library enabled.

For some background on the correct way to install Python when using source code see:


Ignore that it talks about docker, it is still relevant.
