build in MSYS2+Mingw64 on windows 10 64 bits?

[retsyo]

as the title says, I am using windows 10, but I can't make a fresh python:

Any hints? Thanks

$ ./configure --enable-optimizations
...
configure: creating ./config.status
config.status: creating Makefile.pre
config.status: creating Misc/python.pc
config.status: creating Misc/python-embed.pc
config.status: creating Misc/python-config.sh
config.status: creating Modules/ld_so_aix
config.status: creating pyconfig.h
config.status: pyconfig.h is unchanged
creating Modules/Setup.local
creating Makefile


$ make
make: *** No rule to make target 'Modules/Setup.config', needed by 'Makefile'.  Stop.

Any hints?

I guess maybe you didn't set the default line ending as lf, in CI we do so

cpython-mingw/.github/workflows/mingw.yml

Lines 25 to 26 in 2ff76a3

	git config --global core.autocrlf false
	git config --global core.eol lf

Afair, this error happened to me and cloning with lf line ending did fix the issue.
If that's not the issue, I'm not sure why it's happening.

[retsyo]

even I run

           git config --global core.autocrlf false 
           git config --global core.eol lf 

I still get

$ ./configure --enable-optimizations
...
configure: creating ./config.status
config.status: creating Makefile.pre
config.status: creating Misc/python.pc
config.status: creating Misc/python-embed.pc
config.status: creating Misc/python-config.sh
config.status: creating Modules/ld_so_aix
config.status: creating pyconfig.h
config.status: pyconfig.h is unchanged
creating Modules/Setup.local
creating Makefile


$ make
make: *** No rule to make target 'Modules/Setup.config', needed by 'Makefile'.  Stop.

Then I think you didn't run autoreconf before running the configure script. (we didn't update after running it for some reason)

[retsyo]

thanks, finnally I compiled python*.exe on windows 10 64bits in MSYS2+MingW64 by using

autoreconf
./configure --enable-optimizations
make 

however, I get

Python build finished successfully!

To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  msvcrt                time

It is so strange, even math module is not compiled

[lazka]

it should show you the build errors of each module before that summary

[retsyo]

the message is too long, so I post it here: https://github.com/retsyo/misc_bugs/blob/main/cpython20220720.md

[lazka]

hard to say, everything fails to link..

[duanev]

It would be nice to see autoreconf in the build docs somewhere... And currently on a msys2/mingw64 system, there are three versions of autoconf: 2.13, 2.69, and 2.71 - any preference?

[lazka]

Just install the autotools package, it will select the right version at runtime.

Note that the build is currently broken due to a regression in another package.

[duanev]

Ah, I see, autotools picks a working combination of autoconf and automake... Oh and autoconf-archive is needed as well.
