How to read "compiier output "
-
As stupid as it sounds - what are the piece-parts of compiler output ? I need to know where to find the library created.... ...and please do not tell me that "11:19:00" is a time of creation.. Actually - is there a "RTFM" document describing the "compiler output ?

They get picked up by rpath and rpath-link, so that when you use thenlibHCI_VERSION_6622library, you do not have to add them to the link command lineKeep Calm and Carry On
