While fixing a Dll import issue on MacOS I noticed the following:
Mono: DllImport error loading library 'libSystem.Data.dll.so':
'dlopen(libSystem.Data.dll.so, 9): image not found'.
Mono: DllImport error loading library 'libSystem.Data.dll.bundle':
'dlopen(libSystem.Data.dll.bundle, 9): image not found'.
Mono: DllImport error loading library 'libSystem.Data.dll':
'dlopen(libSystem.Data.dll, 9): image not found'.
Mono: DllImport unable to load library 'dlopen(libSystem.Data.dll, 9): image
not found'.
Mono: DllImport attempting to load: 'System.Data.dll’.
By the time my app launches dlopen() has attempted to load
libSystem.Data.dll.whatever 1600 times.
My MacOS app launches and exceutes okay.
Is this normal behaviour on 4.8.0?
It happens on 4.6.x as well, and it seems to be caused by actual
DllImports of 'System.Data.dll':
$ monodis System.Data.dll | grep pinvoke | grep System
.method assembly static hidebysig pinvokeimpl ("System.Data.dll" as
"DllBidTraceCW" unicode cdecl )
.method assembly static hidebysig pinvokeimpl ("System.Data.dll" as
"DllBidTraceCW" unicode cdecl )
...
These look to me like some MS Reference Source artifacts. Maybe
there is a native System.Data.dll under MS.NET which is providing
these exports :) No idea what it is.
