I am cross-posting this on the dev mailing list as I would like to know how to fix this before the 1.73 deadline. Thanks and sorry for cross-posting, Raffi -------- Forwarded Message from the test gmane group Hi, On some teeks workers, I have this strange issue: teeks99-09-p-64: https://www.boost.org/development/tests/develop/developer/output/teeks99-09-... The error says: .../libs/test/test/framework-ts/log-formatter-test.cpp(117): error: in "test_logs": check output.match_pattern(true) has failed: Pattern file can't be opened! which means some files used for testing, such as test/test/baseline-outputs/log-formatter-test.pattern , are not found. Those files are advertised in the Jamfile, https://github.com/boostorg/test/blob/develop/test/Jamfile.v2#L145 I guess it would be a hard error on b2 if the files were not found. What should I do such that those workers find the test files? I recently added one file to the previous 2 existing files. Thanks, Raffi
