Py_UCS4 is not compatible with C++ std::basic_string. Use char32_t as required.
-
There is a lot more then Python 2 removal in these changes. I would like prefer to get this as a patch series with one change at at time. For the usually reasons of its easier to review and not missing issues.
-
Are #13, #14 and this ticket duplicates? Can I just work on the CXX.zip from one of them?

There are compiler options to disable reporting deprecation warning. Check your compiler docs to see what the option is and add it to your build.

But until then the warning will be present unless you know a way to supress them? Yes, the warnings are always appeared and very noisy even if the program doesn't use Py_UNICODE interface. It is very helpful if adding #if switch to suppress them.
-
There is code that uses Py_UNICODE which means that the warning are expected. Once Py_UNICODE is removed from the API then I will #if use of Py_UNICODE to older python versions that support it. But until then the warning will be present unless you know a way to supress them?

I read how pycxx is packaged for fedora and its using setup.py - but distutils can be imported. I'm not sure why that is working like that. Why is distutil available on Fedora? distutils may be importable with 3.12 in some places but upstream https://docs.python.org/3.11/library/distutils.html are clear in "deprecated with removal planned for Python 3.12" and the official docs no longer contain a page for that package for 3.12; it's officially removed with regard to CPython upstream. I will investigate...

I read how pycxx is packaged for fedora and its using setup.py - but distutils can be imported. I'm not sure why that is working like that. Why is distutil available on Fedora? I will investigate and update. Note since all the setup.py does is install files there is no need to define the compiler. PyCXX is a template library with nothing to be compiled. That happens in the projects that use PyCXX.

Hi Barry, I believe the Gentoo package dev-python/pycxx that brought me here uses setup.py and not setup_makefile.py. After a quick look at the Makefile that command python3 setup_makefile.py linux Makefile produced, my impression is: - that it does not have an install target - that the produced files obj/simple.so obj/example.so obj/pycxx_iter.so are not essential (but you tell me) - that g++ would need to be a variable, e.g. $(CXX) - that -g should come from $(CFLAGS) and $(LDFLAGS) to respect...
-
This is a contributed script, that I do not use. Do you have a patch to it that I can use to migrate to setuptools? Or can you use setup_makefile.py? Maybe I should delete setup.py?

distutils not removed from setup.py?

-
Apply patch to remove deprecated <T> where it is not needed.
-
Detect the arch that the python executable supports and build for thoses arch.
-
Update build tooling to allow compiling with g++ -std=XXX options.
-
I'm updating build to allow testing against each standard. Your patch is good for c++11 to c++20 with GCC. I see some issues with c++98 and c++03 but I happy to not support that far back in time. I'll go on to test with MSVC and xcode/llvm next. I think I will not patch python 2 files are these are, I hope, at this point for legacy systems that will not need the patch and may be using very old compilers.
-
Add specific C compiler rules as sharing with C++ does not work on all compilers.

Hi Barry, Here it is. I actually do not use svn. I have been unable to provide a multi-file diff that is understandable by patch. There are 2 files to patch, one for Python2 the other for Python3. I have not tested the patch for Python2 but it is mostly the same as for Python3 (and it is very simple). I have attached the diffs for the individual files and a global file for both by using diff -ru. If you have a look on these files, you’ll see it is very simple. Sorry for the inconvenience. Regards,...

patch does not like the diff. Can you create the diff with svn diff please? Or if you doing this outside of svn then use diff -u? The diff should look like this format: $ diff -u README.txt{~,} --- README.txt~ 2022-08-07 09:54:24.133626013 +0100 +++ README.txt 2022-08-07 09:54:24.133626013 +0100 @@ -2,4 +2,6 @@ Add support for building against python 3.11 alpha 4. +Foo + This Version 7.1.6 with README updates

Thanks. I'll run it pass my tests

Oups, I meant this should not afffect other compilers as this is the standard way to declare constructors.

This issue can be closed as the problem has been fixed by https://sourceforge.net/p/cxx/code/421/

In python2 this was easy to support you just defined the __dir__ property. But that was removed in python3 and there is no direct replacement. What makes this work for python3 is using an API to create classes that I could not see how to use in PyCXX. (I don't have the API details to hand at the moment). Curiously this has been this way with PyCXX since I added python 3.9 support and your maybe the 2nd person to notice. I would love to fix this, but have not figured out how.
