Rebuild tcpSendReceive example of the NDK

Other Parts Discussed in Thread: EK-TM4C1294XL

Hello everybody,

I'd like to rebuild the tcpSendReceive.c file in the directory C:\ti\tirtos_tivac_2_14_04_31\packages\examples\tools. The idea is to use it to communicate with the TIVA C Connected EK-TM4C1294XL evaluation kit running the tcpEcho firmware example. When I use the previuosly built executable file, it works fine. I'd like to rebuild it again using Microsoft's VC 2010. I created a project based on the files in the tools directory above and added the wsock32.lib to the additional dependencies

I followed the instructions found in this page, but it doesn't work. I usually receive this error code:

Error 1 error C2373: 'inet_pton' : nueva definición; modificadores de tipo distintos c:\users\awefky\desktop\ethernet_tiva\sw\2015_12_12\tools\sockets.h 56.

In English, this means that the function "inet_pton" found at line 56 in sockets.h header file has been defined again! When I tried to comment out that definition in the sockets.h file, I get the 4 errors shown in the attached screen shot.

Best regards,

    Hi Ahmed,
    The socket.h file was written to be used for both Linux and Windows. We use Mingw gcc compiler to build the original executable. I can ask around for someone who's done it on Visual Studio to help better. It looks like you're missing some library that has those symbols. From Googling online I see that freeaddrinfo is part of the Ws2_32.dll or previously wsock32.lib for example. Can you check what libraries you're pulling in to build your project?

    Hello Moses,

    Thanks a lot for your informative response. Now the program is working perfectly. I changed the library I'm building against in Visual studio from wsock32.lib to Ws2_32.lib in light of your comment and finally I could bulid my project. The other important point here also is that I couldn't do so without commenting out the inet_pton() inline function in sockets.h.

    I really appreciate your comment.

    Greetings,
