When typing, we normally use the regular lowercase letter, “ b” to represent this sign, but the actual symbol is ♭ which is is a stylized lowercase “b”. Run otool -hV on the library.Let’s take a look at the flat sign. A solution is to load the library it depends on before the lib gets loaded that causes the problem.Īlso interesting to find the solution to your problem: The lib was obviously compiled with a flat-namespace option and requires the symbol to run properly. A library that relies on a symbol needs to know exactly from which library it wants to get the symbol XYZ resolved. In a two-level namespace, instead of a plain table with symbol names, the symbols are saved with name and their library name (so where they come from). It is up to the OS how to deal with collisions, but in most cases it's simply undefined behaviour and leads to a crash because of mixed libraries. A process might load two or more libraries with the same symbol names. One huge disadvantage is the amount of possible collisions. After all symbols were found, the library adds his own symbols to the list. When a library gets loaded it might depend on a symbol and therefore can look in the flat-namespace to find which other library or executable 'offers' it. Two-level namespace and single namespace (also known as flat-namespace).Įach process has a huge table which contains all symbols (functions, external variables. In MacOS there are two so-called namespaces available. Let's first talk about the background of namespaces. Resolving can also work slightly different, depending on the mode though. In previous versions of 'OSX' flat-namespaces were the default. Disclaimer: This answer only applies to macOS 10.4 and higher.
