dll loading error (randomly)

[marcomezzanotte]

Hi, we're randomly experiencing the following error:

Unable to load DLL 'PgCPP.DLL.9.x.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) - at Npgsql.BulkCopy.Native.Versions.PQ9xNativeApi.openRemoteConn(Char hostaddr, Int32 port, Char dbname, Char user, Char password) at Enerj.CDV.Data.DataManagerBase1.InsertBulk(DataTable DT_Tabella)
at Enerj.CDV.Data.DataManager.IndicizzaDocumentInstance(List1 ListID, Int64 IDInstance) at Enerj.CDV.ControlsService.Manager.StartProcess()

The library is used in a Windows Service and the error shows after deploy and installation, while everything works fine in Visual Studio. On the server where we deploy the service, we've installed the Visual C++ Redistributable.

We hope you can give us a hint or a solution for this problem.

Thank you.

Hi!
Okay I'll tomorrow look it

[uzbekdev1]

which version your PG ? 9.5 or 9.4?
Need to update from C:\Program Files\PostgreSQL\9.5 folder lib & dll's

[marcomezzanotte]

Sorry but I don't understand.

When I download the Nuget package, a folder named lipqdll with the following structure is downloaded and what I do is to copy the whole folder structure and contents to the service deployed root folder.

Am I wrong?
What am I supposed to do exactly?

I have the same problem. My postgres instance is on linux server.

How we can get past this error?
I've tried to compile the .DLL but it gives me countless errors ...

Same issue, note im running under Net Core

Ok, looking today.End of this week I pushed a new version.

I have the exact same error. I am using PG 9.5. It all works fine for my unit test project.

I get the Unable to load DLL 'PgCPP.DLL.9.x.dll': The specified module could not be found. error for my MVC web project. Same computer, same database.

I tried adding the lipqDLL folder to the bin folder which worked for my Unit Test project. Did not work still.

I wish the error said the expected directory too so I know where to put the dlls: Unable to load DLL 'C:/Project Folder/bin/PgCPP.DLL.9.x.dll': The specified module could not be found.

Same problem here, but for me it doesn't work even on Visual Studio.

[screig]

I fixed it, I will make a pull request today to merge

I also then want to go on and use costura to embedded the C++ dlls in the Net assembly

[officer-rosmarino]

@screig waiting for it, thanks

[screig]

Ok I have reworked the code base quite a bit

forked version

The C++ projects had hard-coded links to specific installed versions of Postgres. I have made all the C++ projects use relative paths. I also went and tried to go and find the required references, namely the lib and include files for the following versions:

• 9.x x86
• 9.x x64
• 8.x x86
• 8.x x64 (this one I could not find)

I included this data in the code base (bar 8.x x64). I rebuilt the C++ projects which regenerated the missing dlls and copied them over to the C# folder.

@screig could you please point out where you did the changes?

sorry it is still uploading...
