Python 2 reached upstream end-of-life in January 2020. In Fedora Rawhide, it's now provided from the compat package `python27`. Packages that only use Python 2 at build time, like qcint, had a general exception to keep using it in Fedora 31. Now, the dependency should be removed. Switching to Python 3 seemed easy to me (though I don't necessarily know much about qcint). So I opened a pull request: https://src.fedoraproject.org/rpms/qcint/pull-request/1 Could you merge it? If not, if it's possible that the Python 2 build dependency won't get removed in Fedora 33, please let us know; the package will need a FESCo exception. If you need anything from us, or something is unclear, please mention it here.
The package fails to build for unrelated reason now :/ + /usr/bin/cmake -S . -B x86_64-redhat-linux-gnu -DCMAKE_C_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_Fortran_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr -DINCLUDE_INSTALL_DIR:PATH=/usr/include -DLIB_INSTALL_DIR:PATH=/usr/lib64 -DSYSCONF_INSTALL_DIR:PATH=/etc -DSHARE_INSTALL_PREFIX:PATH=/usr/share -DLIB_SUFFIX=64 -DBUILD_SHARED_LIBS:BOOL=ON -DENABLE_EXAMPLE=1 -DWITH_F12=1 -DWITH_COULOMB_ERF=1 -DWITH_RANGE_COULOMB=1 -DQUICK_TEST=1 -DBLAS_LIBRARIES=/usr/lib64/libopenblaso.so .. -- The C compiler identification is GNU 10.1.1 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/gcc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Performing Test QUADMATH_FOUND -- Performing Test QUADMATH_FOUND - Failed -- Found BLAS: /usr/lib64/libopenblaso.so -- Looking for expl -- Looking for expl - found -- Looking for sqrtl -- Looking for sqrtl - found Enabled WITH_RANGE_COULOMB Enabled WITH_COULOMB_ERF Enabled WITH_F12 -- Configuring done -- Generating done CMake Warning: Manually-specified variables were not used by the project: CMAKE_CXX_FLAGS_RELEASE CMAKE_C_FLAGS_RELEASE CMAKE_Fortran_FLAGS_RELEASE ENABLE_EXAMPLE INCLUDE_INSTALL_DIR LIB_INSTALL_DIR LIB_SUFFIX QUICK_TEST SHARE_INSTALL_PREFIX SYSCONF_INSTALL_DIR -- Build files have been written to: /builddir/build/BUILD/qcint-3.0.20/build/x86_64-redhat-linux-gnu + make -j48 VERBOSE=1 make: *** No targets specified and no makefile found.
