EthernetInterface errors while compiling with FRDM-K64F

Hello, I have tried a basic code for EthernetInterface from your cookbooks to start with ethernet communication with FRDM-K64F.

Ethernet

#include "mbed.h"
#include "EthernetInterface.h"

// Network interface
EthernetInterface net;

// Socket demo
int main() {
    // Set static IP
    net.set_network("172.16.23.240", "255.255.255.0", "172.16.23.1");

    // Bring up the ethernet interface
    printf("Ethernet socket example\n");
    net.connect();

    // Show the network address
    const char *ip = net.get_ip_address();
    printf("IP address is: %s\n", ip ? ip : "No IP");

    printf("MAC address is: %s\n", net.get_mac_address());

    // Open a socket on the network interface, and create a TCP connection to mbed.org
    TCPSocket socket;
    socket.open(&net);
    socket.connect("developer.mbed.org", 80);

    // Send a simple http request
    char sbuffer[] = "GET / HTTP/1.1\r\nHost: developer.mbed.org\r\n\r\n";
    int scount = socket.send(sbuffer, sizeof sbuffer);
    printf("sent %d [%.*s]\n", scount, strstr(sbuffer, "\r\n")-sbuffer, sbuffer);

    // Recieve a simple http response and print out the response line
    char rbuffer[64];
    int rcount = socket.recv(rbuffer, sizeof rbuffer);
    printf("recv %d [%.*s]\n", rcount, strstr(rbuffer, "\r\n")-rbuffer, rbuffer);

    // Close the socket to return its memory and bring down the network interface
    socket.close();

    // Bring down the ethernet interface
    net.disconnect();
    printf("Done\n");
}

However a few compile errors occured:

Error: Identifier "socklen_t" is undefined in "EthernetInterface/Socket/Socket.h", Line: 66, Col: 59 Error: Incomplete type is not allowed in "EthernetInterface/Socket/Socket.h", Line: 101, Col: 21 Error: Incomplete type is not allowed in "EthernetInterface/Socket/Endpoint.h", Line: 59, Col: 25 Error: Identifier "SOCK_STREAM" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 30, Col: 22 Error: Incomplete type is not allowed in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 33, Col: 25 Error: Identifier "AF_INET" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 36, Col: 29 Error: Identifier "htons" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 37, Col: 27 Error: Identifier "INADDR_ANY" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 38, Col: 34 Error: Identifier "lwip_bind" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 40, Col: 10 Error: Identifier "lwip_listen" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 52, Col: 10 Error: Identifier "socklen_t" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 70, Col: 6 Error: Identifier "lwip_accept" is undefined in "EthernetInterface/Socket/TCPSocketServer.cpp", Line: 71, Col: 15

No matter what code I use, this one or any template for FRDM-K64F with EthernetInterface, this compile errors appear.

I am using newest mbed-os ( 5.8.3 ) and newest EthernetInterface (rev. 54) including sub libraries.

Yes I did checked this thread: https://os.mbed.com/questions/5225/EthernetInterface-produces-compile-error/

Any suggestions?

Thank you.

Hi Patrik,

Perhaps something has gone wrong migrating an old project. Can you follow these steps using Mbed CLI and let us know how they work:

$ mbed new ethernet_test
$ cd ethernet_test
(place your source file into the ethernet_test folder)
$ mbed ls
ethernet_test ( revision in the current branch)
`- mbed-os (#c05d72c3c005, tags: latest, mbed-os-5.8.3)
$ mbed compile -m k64f -t arm

You should see this output:

What do you mean with source file? The example i used above? Including EthernetInterface library?

I see his output with the example above without library:

I have never used Mbed CLI, there might be errors in settings.

Ok. I finally get it work using gcc_arm and source code from the example. And i got the same output result as yours:

Any suggestions what to do next?

(Sorry for the previous confused comments. Somehow cannot edit them or delete.)

Now that you have the project building you can add the "-f" option to have it flashed to the target for testing:

$ mbed compile -m k64f -t arm -f

A good tutorial on the CLI is available here and the official readme is on the project page: https://os.mbed.com/docs/v5.8/tutorials/quick-start-offline.html https://github.com/ARMmbed/mbed-cli

Flashing works, however, I am afraid I misunderstood your first answer. I used source code without ethernetinterface library. Now when compiling with library, fllowing errors appears using CLI:

Errors are pointing to the EthernetInterface library, like it does using mbed online compiling.

Any suggestions?

Thank you
