Re: [microblaze-uclinux] sysv ipc support on microblaze

[Jim Van Vorst <jvanvorst@xxxxxxxxx>]

John,
Still no-go.  I applied the patch and get the same error:
   if ((msqid = msgget(key, 0644 | IPC_CREAT)) == -1) {
       perror("msgget");
       exit(1);
   }

results in
msgget: Function not implemented

I verified the files are patched and rebuilt. (syscall_table.S and 
sys_microblaze.c).
Is this the full patch?

Thanks,
Jim
