CompressorImplementation

Hi, Alexandre,

IW15.6.0
ServerController.Compression.CompressorImplementation:

The comp LibDeflate method is now activated by default and causes an access violation right at startup without further informations.
After switching to compZLib it works again

I can confirm that the compression using an external LibDeflate Dll is working now in IW15.6.1 with C++Builder 12

How does it work? I'm using also C++ Builder 12 (IW 15.6.2)

ServerController.CompressorImplementation = compLibDeflate;
ServerController.Enabled = true;
ServerController.UseExternalLib = true;

IWLibDeflate32.dll is located in the application dir (...\Win32\Debug)

the log file says:

Could not initialize LibDeflate compression. Switching to zlib compression.

Does anyone have a tip for me?

This are my settings

Thank you very much. These are exactly my settings.

Is anything else necessary (LoadLibrary, Typelib)? The log still shows me:

Could not initialize LibDeflate compression. Switching to zlib compression. 

Best regards

Witch are the pros and cons between UseExternalLin set to True and False?

C++ Builder only supports UseExternalLib = true.

I can't confirm this, I'm using the server with internal and external library.

...if I try LibDeflate in C++ Builder (IW 15.6.2)

I suspect your application is not looking for the library where you think.
