Hi Stefan, Apologies for breaking the reply chain; I wasn't subscribed to the list earlier, so this is the only message I could reply to. Now I should be able to reply to other messages.
Thanks for your email. I don't think that ./b2 has the option to specify the python version within --with-python - I think only ./bootstrap does. When I tried ./b2 --with-python=3.7 I got; *****BEGIN OUTPUT***** error: wrong library name 'python=3.7' in the --with-<library> option. *****END OUTPUT***** Then, I tried invoking ./b2 with option python=3.7. sudo ./b2 python=3.7 --with-python *****BEGIN OUTPUT***** /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build/feature.jam:491: in feature.validate-value-string from module feature error: "3.7" is not a known value of feature <python> error: legal values: "2.7" /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build/property.jam:333: in validate1 from module property /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build/property.jam:359: in property.validate from module property /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build/build-request.jam:271: in convert-command-line-element from module build-request /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build/build-request.jam:222: in build-request.convert-command-line-elements from module build-request /Users/Mort/Downloads/boost_1_74_0/tools/build/src/build-system.jam:774: in load from module build-system /Users/Mort/Downloads/boost_1_74_0/tools/build/src/kernel/modules.jam:295: in import from module modules /Users/Mort/Downloads/boost_1_74_0/tools/build/src/kernel/bootstrap.jam:139: in boost-build from module /Users/Mort/Downloads/boost_1_74_0/boost-build.jam:17: in module scope from module *****END OUTPUT***** Either way, it seems like the ./b2 program doesn't recognize version 3.7, only 2.7. Let me know if you need any more information. Any help is greatly appreciated.
