Hi,
If anyone has an insight, experience or even hint on this one, this would be
greatly appreciated.
I have a C# application that loads the a native shared library (the R shared
library). I use DllImport as follows:
[DllImport("libdl")]
private static extern IntPtr dlopen([MarshalAs(UnmanagedType.LPStr)]
string filename, int flag);
[DllImport("libdl")]
[return: MarshalAs(UnmanagedType.LPStr)]
private static extern string dlerror();
full code at
https://rdotnet.codeplex.com/SourceControl/latest#RDotNet.NativeLibrary/UnixLibraryLoader.cs,
and the test application is at
https://rdotnet.codeplex.com/SourceControl/latest#TestApps/SimpleTest/Program.cs.
I can run this application on a Debian Linux x64 box. However on a CentOS, and
try as I might to have similar setups, I get a failure with the cryptic dlerror
message 'dlopen: invalid caller'. I was surprised to see only sparse info on
the net on this message. I can load the shared library successfully with a
simple C program code.
