[Mono-osx] Problem building and using a Cocoa .dylib

[Hess, Philip J]

It's probably actually finding libcairo.dylib in Mono.framework, _not_ the libcairo.dylib in your executable's folder.

Here's some information:

http://www.mono-project.com/DllNotFoundException


Normally a .dylib would not have any UI stuff in it, so your library probably doesn't need the AppKit.framework.

Thanks.

-Phil

The exception is "System.DllNotFoundException: my.dylib"

Same error if I name it "libmy.dylib".

If I copy "libcairo.dylib" from the Mono library to the same location as
my.dylib and use
[DllImport("libcairo.dylib", EntryPoint = "myProc", SetLastError = true,
CallingConvention = CallingConvention.Cdecl)]
It finds the library, but gives the error
"System.EntryPointNotFoundException: myProc" which is to be expected.

So it must be something about the structure of my.dylib. The Xcode project
for it lists Cocoa.framework, AppKit.framework, CoreData.framework and
Foundation.framework
