[Dev-C++] Trouble compiling winsock programs.

[Manoj S. <sha...@ro...>]

Hi,

I am trying to compile a simple winsock program using Dev-C++ and get the
following error
[Linker error] undefined reference to WSAStartup@8. I tried generating my
own libwsock32.a   library using the wsock32.dll on  my system with the help
of the dllwrap utility and linking it to my program by copying the generated
.a file to the lib directory but the error stayed the same.

I also tried using an older version of wsock32.dll (since I have the latest
version of the dll) and it may not be compatible with the header files as
supplied by Dev-C++. But this gave me the same undefined reference error.

As a last resort I tried using the header files supplied by the Microsoft
SDK instead of the include directory header files as supplied by Dev-C++. I
get a target architecture must be defined error. An attempt to #define
_M_IX86 which is the macro that needs to be defined leads to further errors,
so I would prefer not to go down that path further.

Can anyone suggest what else can be done to get a very simple winsock
program to work. I have the XP OS on a Pentium machine.

Regards,
Manoj.

Just because a file is present in the `lib' directory, doesn't mean that
it'll be linked in. You need to add it to your the list of libraries the
linker must add. Add `-lwsock32' to the linker command-line. Any lib by the
name `libfoo.a' in the `lib' directory has to/can be linked in using -lfoo.

HTH.

Hi,

Thanks for your prompt responses!

I should have mentioned in my earlier that I did try adding the -lwsock32
option to the linker command line.I tried it once again though and the
result was the same as before.The undefined reference error to WSAStartup
error still shows up.

Also I would like to run this a stand alone  file (not a project). Any
suggestions?
Thanks in advance once again for your help.

Regards,
Manoj.

In the linker options, where one adds libraries, I have this:

C:/Dev-Cpp/lib/libws2_32.a

for my winsock2 projects

Try linking in the WinSock2 lib, as Charles mentioned.

For this, you might want to use the command-line/make, or else, specify in
compiler options that you want the WinSock lib to be linked with all your
programs. Remove it once you're done with this project. Bit of a hassle.
Command-line would be better.

That did the trick! Adding -lws2_32 to my command line is just what the
doctor ordered.

Thanks a lot for your help guys! It is greatly appreciated.

    Just add "c:\Dev-c++\Lib\libwsock32.a" (supposing you have Dev-c++
installed on drive C) in the project options, under "Further object files or
linker options".
