Hi Graham,

One year ago I installed successfully mod_wsgi-4.6.5 with python 3.7.1

now I am installing on a different server the same with python 3.8.1 (RHEL7)

I followed same steps but can not get the mod_wsgi.so created. can not find where I am wrong

I found known error from May 2019 but the version I use include the corrections.

Here are the steps :

1)

./configure --with-python=/usr/local/bin/python3.8

checking for apxs2... no

checking for apxs... /usr/bin/apxs

checking for gcc... gcc

checking whether the C compiler works... yes

checking for C compiler default output file name... a.out

checking for suffix of executables...

checking whether we are cross compiling... no

checking for suffix of object files... o

checking whether we are using the GNU C compiler... yes

checking whether gcc accepts -g... yes

checking for gcc option to accept ISO C89... none needed

checking for prctl... yes

checking Apache version... 2.4.6

configure: creating ./config.status

config.status: creating Makefile

2)

make

Use the latest version of mod_wsgi source code if needing to using Python 3.7+. The error indicates you are using an older version of the mod_wsgi source code from before it supported Python 3.7.

Hi Graham

I downloaded again from https://github.com/GrahamDumpleton/mod_wsgi/archive/4.6.5.tar.gz

I see not other version more recent than 22 October 2018.

I still get the same error at make.

let me know if I am wrong before I am reverting back to the older version of python 3.7.1 (instead of 3.8.1)

Thanks

Eric

There are 4 newer releases.

Seems I forgot to add release notes to entry, so GitHub hides them.
