I have a simple c# app trying to PInvoke to a shared library on my Mandrake
10 box using Mono-0.31.
I assumed that mono would look in the current directory but it seems my
assumption is wrong since the so in question does exist.
I'm even hardcoding the path in my DllImport attribute:
[
DllImport
(
"/home/martin/source/foo",
EntryPoint="MyFunc",
CharSet=CharSet.Ansi,
CallingConvention=CallingConvention.Cdecl
)
]
private static extern IntPtr MyFunc(int v,
[MarshalAs(UnmanagedType.LPArray, ArraySubType=UnmanagedType.LPStr)]
string[] a, string n);
Please bear in mind that I'm not a very experienced linux user so in all
likelihood I've done something profoundly stupid or overlooked something
really obvious.
Where does mono look for so's?
Thanks,
Martin
