Hi Leon, sorry for overlooking your previous post. In your config.log you see
real_configure:40317: checking whether any of bzip2 liblzma libffi zlib is installed as or will be installed as SPKG real_configure:40322: result: yes; install python3 as well That is, one of system packages providing bzip2 liblzma libffi zlib is missing. One can find in config.log which one(s): bzip2 is OK: real_configure:17816: will use system package and not install SPKG bzip2 zlib is OK: real_configure:14120: will use system package and not install SPKG zlib but liblzma is not: real_configure:35414: no suitable system package found for SPKG liblzma and libffi is not: real_configure:34155: no suitable system package found for SPKG libffi You should install libffi-dev, xz-utils, and liblzma-dev. I.e. please run sudo apt-get libffi-dev xz-utils liblzma-dev and then re-try running /configure. Then your python3 is hopefully recognsed. Actually, we have an advice to use the list of packages to install for Ubuntu/Debian, here: https://sagemanifolds.obspm.fr/install_ubuntu.html Please check that all these are installed. (and if you get errors installing them, please report) Best Dima -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
