Error loading FPLibrary from local system

Have you installed the full Centera SDK, including all the relevant DLL files? It looks like you are using the Java SDk and you probably don't have the underlying required C SDK libraries installed and on your PATH.

Thanks Graham for the post,

I installed "CenteraTools_4_1_WIN.exe" and not the error message has changed to

Failed to  authenticate PEA data(-10153)

This is thrown at the  following line of code

FPPool  thePool = new FPPool(poolAddress);

Could you let me know the reason.

Thanks in advance

Hi Prashant,

This error points to an issue with the PEA file you are using. Please check to make sure you are using a valid PEA profile or are using a valid name/secret combination. Which Centera cluster are you using to test? Did you get the PEA file from this list of available Centera clusters?

Thanks,
Zeeshan

As long as they are on your PATH or in the processes current working directory when it runs, then thats fine

these?

FPCore.dll

FPLibrary.dll

FPLibrary.lib

fpos32.dll

fpparser.dll

FPStreams.dll

FPUtils.dll

FPXML.dll

pai_module.dll

do i need to install anything to get these in the right location, or can i simply copy them to a specific location?  would my deployment folder be a suitable place to park them, as long as that folder is in the PATH variable?

thanks paul.

Are the DLLs on your PATH on this server?

yes you'll need all the files that are in the lib dir on the SDK download

hi paul-

thanks for the quick response!  the only "centera" file that currently resides on that server is the fpsdk dll in my deployment folder.  i'm guessing i'll have to install others?

thanks

i copied them over and volia!  the sun is shining and the birds are chirping...all is well in centera-land!

thanks ever so much for helping me get this back on track, paul.

cheers

good morning graham-

i find myself in a similar quandry.  i have developed an extensive centera "dashboard" in visual studio 2008 and c# using the most recent fpsdk (3.2.4.0 nov09).  everything is singin' and dancin' on my pc (xp sp3 x86).  i have specified in my .net solution to "copy local" the fpsdk dll upon deployment.

now that i have deployed the exe to one of our x64 servers, i get the same "error loading fplibrary" complaint from the server.  i surmise there is more to supporting the deployment vis-a-vis the fpsdk than simply copying the dll to the deployment folder?  what will i have to do to satisfy the seemingly persnickity server?

thanks graham.

here are my notes to myself once I got it all up and running...hope it helps:

Centera Setup/Requirements

There are a number of prerequisites that must be satisfied prior to a successful deployment of any Centera C# project:

1) Perl

Some suitable incarnation (ActivePerl, etc.) must be installed on the box where development is done.

The install must include adding the location of the Perl components to the PATH system variable.

2) Centera SDK (v3.2.705 as of Dec2009)

Extract the following files from the latest version of the SDK into the DEBUG folder of the VS project:

FPLibrary.dll

Fpos32.dll

Fpparser.dll

Pai_module.dll

3) PEA Files (Pool Entry Authorization)

These files are created and distributed by the local Centera administrator, and should be placed in a location on the dev/prod box which is known to the deployed code.

4) .NET Interface API library ( FPSDK.dll =>“.NET Wrapper”)

This dll needs to be a reference in the VS project. It is obtained from SourceForge (FPApi.NET.zip) and will need to be opened and compiled from VS.

The resulting dll can then be copied to a known location to resolve any project references.

cheers

I'm having the same issue, and it doesn't seem to matter where I put the FPLibrary.dll file, I still get this error. Can you give me some specifics about the PATH and current working directory that you refer to. I'm learning as I go, working with a sample project, Adrd Project Centera 1, and have the following files in the Visual Studio 2010\Projects\AdrdProjectCentera1\bin\Debug directory.

AdrdProjectCentera1.exe

AdrdProjectCentera1.pdb

AdrdProjectCentera1.vshost.exe

AdrdProjectCentera1.vshost.exe.manifest

FPLibrary.dll

fpos32.dll

fpparser.dll

FPSDK.dll

FPSDK.pdb

pai_module.dll

us1_profile1_rwqe.pea

us1_profile2_rwqedp.pea

us1_profile3_rwqedpD.pea

us2_profile1_rqecw.pea

us2_profile2_rdqecw.pea

us2_profile3_rdqeDcw.pea

us3_profile1_rqecw.pea

us3_profile2_rdqecw.pea

us3_profile3_rdqeDcw.pea

us4_profile1_rwqec.pea

us4_profile2_rwqecd.pea

us4_profile3_rwqecdD.pea

us5_profile1_rwqec.pea

us5_profile2_rwqecd.pea

us5_profile3_rwqecdD.pea

For the PRSDK.dll, I copied the project to my machine, built it, then copied the FPSDK.dll and FPSDK.pbd to this directory. Then added it to the sample project.

I'm new to Centera development, so any help is really appreciated.

In kjward's earlier post he states you need Perl - you don't for the latest versions of the .NET wrapper. In earlier versions, there were issues with runtime signatures that required patching of the IL, which was done by Perl scripts. In the later versions, this is handled by attributes that became available in later version of the .NET Framework.

Also - you should never put unmanaged DLLs (i.e. DLLs that are not .NET assemblies) in the same directory as your deployed .NET application and any additional assemblies it uses (in this case, FPSDK.DLL - which, ideally, should be added to the GAC and included there).

The native Windows DLLs (in this case the underlying Centera SDK DLLs) should be put in a directory on your Windows search PATH.

Looks like you have a space in your PEA file path. If that is the case, you need to "escape" that as well.

Are you running on Vista? Note that this this is not officially supported and you may hit problems!!

Graham,

  I removed the space in the file path.

I still get the same error when running this line.

Are there any other things I should be looking for?

Currently my development machine is Window 7 Professional with SP1.

My very simple code is as follows:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

using EMC.Centera.SDK;

namespace Centera_Test
{
public partial class Form1 : Form
{
  const String CENTERA_PEA_LOCATION = "C:\\Users\\nrushefsky.VISTASG\\Documents\\PEAFiles\\emea3profile1_rdqeDcw.pea";
  public Form1()
  {
   InitializeComponent();
  }

  private void btnConnect_Click(object sender, EventArgs e)
  {
   try
   {
    FPPool.OpenStrategy = FPMisc.LAZY_OPEN;
    EMC.Centera.SDK.FPPool thePool = new FPPool(CENTERA_PEA_LOCATION);
   }
   catch (Exception ex)
   {
    MessageBox.Show(ex.Message);
   }
  }
}
}
