Hi, I am attempting to use BCP to put boost into a different namespace as below: mkdir myboost_1_88_0 curl -L https://archives.boost.io/release/1.88.0/source/boost_1_88_0.tar.bz2 | tar -xvjf - cd boost_1_88_0 && ./bootstrap.sh && ./b2 tools/bcp && ./dist/bin/bcp --namespace=myboost . ../myboost_1_88_0 cd ../myboost_1_88_0 ./b2 This results in: … error: Unable to find file or target named error: '/boost/align//boost_align' error: referred to from project at error: '/home/mloyet/external/boost-test/myboost_1_88_0/libs/atomic/build' The snippet appears to work for 1.84.0. Has something changed? Am I invoking BCP incorrectly? ________________________________ Note: This email is for the confidential use of the named addressee(s) only and may contain proprietary, confidential, or privileged information and/or personal data.
