[Gambas-user] Cannot find proprietary shared libraries.

[ML]

Guys, need help accessing proprietary shared libs from Gambas (v3.11.2)
from PPA in Ubuntu 16.04 x64.

I've been given -after signing an NDA with a company- a couple of
development .so files.

I placed these .so files in a subfolder inside my home folder.
I've put this path inside a .conf file, put this .conf file inside
/etc/ld.so.conf.d and ran ldconfig as superuser.
I verified the libs and their location are in the cache by grepping the
output from ldconfig -p: They are both there.

But alas! Gambas cannot find them. I have this sample code (sorry,
cannot give real code details 'cos of the NDA):

Lib call declaration in a module (say it is called modLib):

  'The call name used is the actual call name, respecting
upper/lowercase, ie: no need for EXEC.
  Public Extern SomeLib_GetVersion(versionStrPtr As Pointer) In "libName"

I also have a form with -appx- the following code:

  Public Sub Form_Open()

    Dim libVersion As String = String(128, " ")
    Dim strPtr As Pointer = VarPtr(libVersion)

    Try modLibrary.SomeLib_GetVersion(strPtr)
    If (Error.Code) Then
      Message.Error(Error.Text)
    End If

  End

When I call this from a form, I get the following error:

  Cannot find dynamic library 'libName.so': libName.so: cannot open
shared object file: No such file or directory

Now, I've seen lib names with a trailing colon and (version?) number. I
don't know how or where can I get this info from, or if I need them.

How can I get Gambas able to find and use these .so files?
Regarding these trailing ":<number>" in EXTERN declarations: How do I
find these out, and how do I know whether I need them or not?
