Логично. Не лучше ли к каждой строчке длинного текста дописать, какой компонент его породил, как и к формальному сообщению? И вообще взять за правило приписывать префикс к выводу. Например, так: > process-lto: ERROR: ./usr/lib64/libfoo.a: contains __gnu_lto_slim > process-lto: Most likely this file contains GIMPLE bytecode that should NOT be packaged > process-lto: since its format can change between GCC versions. > process-lto: Use -ffat-lto-objects option to package machine code in static libraries, e.g. > process-lto: %{?optflags_lto:%global optflags_lto %optflags_lto -ffat-lto-objects} > process-lto: Alternatively, you might want to stop packaging static libraries. Сборочный лог является продуктом более десятка компонентов, читателю будет удобнее пропускать ненужное. [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 833 bytes --]
