Hi there! In the project which has both TServerSocket and Indy components compiler says multiple declaration for fd_set (in winsock2.h) and Earlier declaration of fd_set (in winsock.h) How to handle this? Thank You -- Regards, Sergey Muschin

By not using multiple socket libraries in the same project to begin with. Winsock.h and Winsock2.h cannot coexist in the same project together. Why are you using TServerSocket if you are also using Indy? Why are you using Indy if you are using TServerSocket? Gambit

Move the Indy includes above the TServerSocket includes. HTH Jonathan

That does not usually work, because the VCL includes windows.h, which in turn includes winsock.h before any VCL headers are included. If winsock.h is included before winsock2.h then all hell breaks lose with winsock2.h, as is evident by Sergey's original message. On the other hand, if winsock2.h is included before winsock.h, winsock2.h disables winsock.h and all is good. Gambit

I do not recommend that. A better "hack" would be to simply make the Win32 API headers include winsock2.h instead of winsock.h. Gambit

So then the OP should change his unit.cpp to read #include <winsock2.h> #include <vcl.h> Jonathan

To solve this problem, I included '_WINSOCKAPI_' in the conditional defines (from the project options). Is this a bad solution? It works, though... []'s Nelson
