It doesn't contain needed `.pc` files for `pkg-config`, so during compilation correct flags aren't added.\r\n\r\nDuring compilation and building debug environment I've got:\r\n```\r\ngcc -pthread -shared -L/opt/wargaming/wargaming-python311/root/usr/lib64-Wl,-z,relro -Wl,-rpath,/opt/wargaming/wargaming-python311/root/usr/lib64 -\r\nWl,--enable-new-dtags -g -L/usr/lib64/openssl11 -L/usr/lib64 -L/opt/wargaming/wargaming-python311/root/usr/lib64-Wl,-z,relro -Wl,-rpath,/opt/wargam\r\ning/wargaming-python311/root/usr/lib64 -Wl,--enable-new-dtags -g -L/usr/lib64/openssl11 -L/usr/lib64 -L/opt/wargaming/wargaming-python311/root/usr/\r\nlib64-Wl,-z,relro -Wl,-rpath,/opt/wargaming/wargaming-python311/root/usr/lib64 -Wl,--enable-new-dtags -g -L/usr/lib64/openssl11 -L/usr/lib64 -flto\r\n-fuse-linker-plugin -ffat-lto-objects -flto-partition=none -g -L/opt/wargaming/wargaming-python311/root/usr/lib64-Wl,-z,relro -Wl,-rpath,/opt/warga\r\nming/wargaming-python311/root/usr/lib64 -Wl,--enable-new-dtags -g -L/usr/lib64/openssl11 -L/usr/lib64 -L/opt/wargaming/wargaming-python311/root/usr\r\n/lib64-Wl,-z,relro -Wl,-rpath,/opt/wargaming/wargaming-python311/root/usr/lib64 -Wl,--enable-new-dtags -g -L/usr/lib64/openssl11 -L/usr/lib64 -I/op\r\nt/wargaming/wargaming-python311/root/usr/include -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffe\r\nr-size=4 -grecord-gcc-switches -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -I/usr/include/openssl11 -I/usr/include build/temp.linux-x86_64-3.11\r\n-pydebug/builddir/build/BUILD/Python-3.11.0rc1/Modules/_ctypes/_ctypes.o build/temp.linux-x86_64-3.11-pydebug/builddir/build/BUILD/Python-3.11.0rc1\r\n/Modules/_ctypes/callbacks.o build/temp.linux-x86_64-3.11-pydebug/builddir/build/BUILD/Python-3.11.0rc1/Modules/_ctypes/callproc.o build/temp.linux\r\n-x86_64-3.11-pydebug/builddir/build/BUILD/Python-3.11.0rc1/Modules/_ctypes/cfield.o build/temp.linux-x86_64-3.11-pydebug/builddir/build/BUILD/Pytho\r\nn-3.11.0rc1/Modules/_ctypes/stgdict.o -L. -L/opt/wargaming/wargaming-python311/root/usr/lib64 -L/usr/lib64/openssl11 -L/usr/lib64 -L/usr/local/lib\r\n-lffi -ldl -o build/lib.linux-x86_64-3.11-pydebug/_ctypes.cpython-311d-x86_64-linux-gnu.so\r\n*** WARNING: renaming \"_tkinter\" since importing it failed: /builddir/build/BUILD/Python-3.11.0rc1/build/debug/build/lib.linux-x86_64-3.11-pydebug/\r\n_tkinter.cpython-311d-x86_64-linux-gnu.so: undefined symbol: Tcl_AddErrorInfo\r\nFollowing modules built successfully but were removed because they could not be imported:\r\n_tkinter\r\n```\r\n\r\nIt seems that I need correct `TCLTK_CFLAGS` and `TCLTK_LIBS`, but it's quite problematic to find it manually and it's better than on Centos7 it will be detected automatically.\r\n\r\nAdding in SPEC file the next string:\r\n`export TCLTK_LIBS=\"-ltk8.5 -ltcl8.5\"`\r\nsolves the issue.\r\n\r\n# Your environment\r\n\r\ndocker with mock inside, devtoolset-9 is present, openssl11.\r\n- CPython versions tested on: 3.11rc1\r\n- Operating system and architecture: Centos7, x86_64\r\n","author":{"url":"https://github.com/sharewax","@type":"Person","name":"sharewax"},"datePublished":"2022-08-13T15:31:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/95957/cpython/issues/95957"}
