Error: Cannot find fpsock used by MainForm of the Project Inspector

Hi, I'm trying to use TTCPClient from fcl-net but got this error
Error: Cannot find fpsock used by MainForm of the Project Inspector.

Should I install some extra package
Is it a good idea to use it at all or its better to go for 3rd party implementations.

fpsock is linux unit afaik.

Is it a good idea to use it at all or its better to go for 3rd party implementations.

If fpsock not for windows, then yes need 3rd party

There must be something else going on. But fpsock is unix, that is correct.

The code seems not written for fcl-net's fpsock.TTcpClient, because several methods and properties in the above code do not exist in TTcpClient from fpsock.

Looks more like Delphi's old TTcpClient? (Which has been deprecated since D7)

The cross-platform TCP client in fcl-net is TInetSocket in the ssockets unit.

Thank you, Thausand and Thaddy

To summarize
- fpsock unit is specific for unix, linux
- ssockets unit contains the cross-platform TCP client TInetSocket
- both of them are part of fcl-net package

I reduced the example code, not to confuse someone reading this in the future.
