I have a shared library (created in PB[C]) that I can successfully load and call from my code in the PB IDE but when I compile my program (also PB[C]) it then fails to load the library.

Any ideas what the problem could be?

Code: Select all

Prototype Prototype_ServerStart(nPort, *sRootDir, *RouterFunction, *FreeFunction, *ErrorFunction)
Prototype Prototype_ServerStop()
Global ServerStart.Prototype_ServerStart
Global ServerStop.Prototype_ServerStop

Global sLibName.s = "appserver.so"
CompilerSelect #PB_Compiler_OS
  CompilerCase #PB_OS_Windows
    sLibName = "appserver.dll"
CompilerEndSelect

Global server_lib = OpenLibrary(#PB_Any, sLibName)
If server_lib
  ServerStart = GetFunction(server_lib, "ServerStart")
  ServerStop  = GetFunction(server_lib, "ServerStop")
Else
  MessageRequester("Error", "Failed to load library", 0)
  End
EndIf

perhaps missing path to library

You're right.
From the IDE I can just use the library name (it's in the same folder as the code) but once compiled I have to provide the full path.

This seems to be an undocumented issue as I ran into it some years ago with the Chilkat library. You need the full path in the compiled version of your application.

If the .so is in the same dir of the executable, you should be able to open it using "./" before the name instead of the full path.
I do it this way under windows and linux and it works.
Anyway using the full path is not a big problem since it can be easily obtained programmatically, so ...
