cross compiling a c program for imx6

sameerarvikar — Wed, 27 Sep 2017 10:32:37 GMT

Hello,

I am trying to cross compile following c (tcp socket server)program for imx6

using following command

arm-poky-linux-gnueabi-gcc tcpserver.c --sysroot=/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/lib -o server_tcp -I/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/include

I have include -I option cause error was coming stdio.h

Now error is coming

/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/include/gnu/stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory

so i edited stubs.h

so it won't use stubs-soft.h

Now following error is coming

/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/5.3.0/real-ld: cannot find crt1.o: No such file or directory

collect2: error: ld returned 1 exit status

how to solve the issue ,the program is compiling and running without problem in ubuntu(on pc)

tcpserver.c
/****************** SERVER CODE ****************/
#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <string.h>
int main(){
int welcomeSocket, newSocket;
char buffer[1024];
struct sockaddr_in serverAddr;
struct sockaddr_storage serverStorage;
socklen_t addr_size;
/*---- Create the socket. The three arguments are: ----*/
/* 1) Internet domain 2) Stream socket 3) Default protocol (TCP in this case) */
welcomeSocket = socket(PF_INET, SOCK_STREAM, 0);

/*---- Configure settings of the server address struct ----*/
/* Address family = Internet */
serverAddr.sin_family = AF_INET;
/* Set port number, using htons function to use proper byte order */
serverAddr.sin_port = htons(7891);
/* Set IP address to localhost */
serverAddr.sin_addr.s_addr = inet_addr("127.0.0.1");
/* Set all bits of the padding field to 0 */
memset(serverAddr.sin_zero, '\0', sizeof serverAddr.sin_zero);
/*---- Bind the address struct to the socket ----*/
bind(welcomeSocket, (struct sockaddr *) &serverAddr, sizeof(serverAddr));
/*---- Listen on the socket, with 5 max connection requests queued ----*/
if(listen(welcomeSocket,5)==0)
    printf("Listening\n");
else
    printf("Error\n");
/*---- Accept call creates a new socket for the incoming connection ----*/
addr_size = sizeof serverStorage;

int n = 0, k;
char recvBuff[1024];
while(1)
{
newSocket = accept(welcomeSocket, (struct sockaddr *) &serverStorage, &addr_size);
/*---- Send message to the socket of the incoming connection ----*/
strcpy(buffer,"Hello World\n");
send(newSocket,buffer,13,0);
   n = recv(newSocket, recvBuff, 1023, 0);
     printf("Recd: %d bytes\n",n);
     printf("Data received: %s",recvBuff);
    /* printf("recvbuff --> %s \n",recvBuff); */
/* for (k=0; k<16; ++k) { printf("%d: 0x%02s, ", k, recvBuff[k]); }
     sleep(1);*/
   printf("\n");
}

return 0;
}

Hello sameerarvikar,

This error may be related to the libraries not being found when cross-compiling. One alternative would be looking for the libraries on your gcc location and adding them to LIBRARY_PATH.

I would recommend looking at the following thread where they set a flag to point to where the target sysroot is, which allows the cross compiler to find the libraries:
