Here https://docs.python.org/3/whatsnew/changelog.html for bpo-45067 is referenced Centos, I think the same applies to Gentoo. I have the latest ncurses: =sys-libs/ncurses-6.3_p20211106 Reproducible: Always Steps to Reproduce: 1. add "=dev-lang/python-3.10.1 -ncurses" to /etc/portage/package.use/package.use_file 2. it builds 3. comment the above line 4. it doesn't build
Created attachment 757619 [details] Emerge build log when ncurses flag is enabled for python-3.10 (and 3.11)
From build.log: x86_64-pc-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,--as-needed -Wno-unused-result -Wsign-compare -DNDEBUG -O2 -pipe -fwrapv build/temp.linux-x86_64-3.10/var/tmp/portage/dev-lang/python-3.10.1/work/Python-3.10.1/Modules/_cursesmodule.o -L. -L/usr/local/lib64 -lncurses -o build/lib.linux-x86_64-3.10/_curses.cpython-310-x86_64-linux-gnu.so I guess an old ncurses remains installed under /usr/local/lib64.

Good point, this folder recurs in the log, but is empty, and its permissions look fine: # ll -a /usr/local/lib64 total 8 drwxr-xr-x 2 root root 4096 30 mar 2020 . drwxr-xr-x 13 root root 4096 19 apr 2021 .. # ll /usr/local/lib64 -d drwxr-xr-x 2 root root 4096 30 mar 2020 /usr/local/lib64
I found the problem. It was not ncurses per se, it was impossible to compile python 3 when both ncurses and readline flags were present at the same time. I discovered, when analyzing the output of: merge-usr --dryrun a couple of old libraries from 2009: [...] ERROR: Conflict for file '/lib64/libhistory.so': [Errno 17] File exists: '/usr/lib64/libhistory.so' ERROR: Conflict for file '/lib64/libreadline.so': [Errno 17] File exists: '/usr/lib64/libreadline.so' ERROR: Leaving '/lib64' as a directory due to prior errors [...] I don't know where those file came from. I deleted the offending files and, sure enough, now python compiles with both ncurses and readline flags. I'm closing this bug report.
