i tried with some other kernel version….but there is also the same problem…

the error have one line: /lib64/libncursesw.so.5 not found..bt as i checked this .so is present at that path…

 

/bin/ld: warning: libdl.so.2, needed by /lib/../lib64/libncursesw.so.5, not found (try using -rpath or -rpath-link)

as we check the value through :
printk(KERN_INFO “semophore count= %d\n”,(int)&sculldev->sem.count);

but it shows the negative value….

Is there any other way to check the semophore variable…Please guide…
