Here is my source, so far just early stages: [code] #include <errno.h> #include <fcntl.h> #include <termios.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <time.h> #include <unistd.h>

When I try to execute the application on the Beaglebone Black I get: [code] root@beaglebone:/home/debian# ./helloWorldC ./helloWorldC: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.17' not found (required by ./helloWorldC) [/code] Any suggestions? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
