What is wrong with build kernel?

[Altera_Forum]

PLS help..... 

Sir,  when I build the Microtronix nios2linux v1.1 kernel,the wrong below become.  First,I setup the Microtronix nios2linux v1.1 by download from "Nios Dscussion Board-->Downloads-->Linux 2.6 Distribution for Nios II" in this forum.  Then I setup a kernel project in Nios II IDE.after configure the kernel, I build the project.It is no error and run it correctly.  But when I import the all programs and decuments in "altera\kits\nios2\bin\eclipse\plugins\com.microtronix.nios2linux.kernel_0.1.5\linux-2.6.x" to the kernel_1s10\build\src,then build the kernel project some error become.the Error like below: Kind Status Priority Description Resource In Folder Location Error *warning: unused variable `auth'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/net/sunrpc/auth.c] kernel_1s10 line 325 Error *warning: unused variable `auth'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/net/sunrpc/auth.c] kernel_1s10 line 338 Error *warning: unused variable `auth'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/net/sunrpc/auth.c] kernel_1s10 line 350 Error *warning: unused variable `auth'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/net/sunrpc/auth.c] kernel_1s10 line 390 Error *warning: signed size_t format, __kernel_size_t arg (arg 2)[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/net/sunrpc/svc.c] kernel_1s10 line 413 Error *warning: unused variable `dentry'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/fs/nfs/write.c] kernel_1s10 line 674 Error *warning: unused variable `task'[/cygdrive/d/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/fs/nfs/write.c] kernel_1s10 line 756 Warning passing arg 2 of `__request_region' makes integer from pointer without a cast pio.c kernel_1s10/build/src/arch/nios2nommu/kernel line 114 Warning passing arg 2 of `__request_region' makes integer from pointer without a cast pio.c kernel_1s10/build/src/arch/nios2nommu/kernel line 119 Warning passing arg 2 of `__release_region' makes integer from pointer without a cast pio.c kernel_1s10/build/src/arch/nios2nommu/kernel line 139 Warning passing arg 2 of `__release_region' makes integer from pointer without a cast pio.c kernel_1s10/build/src/arch/nios2nommu/kernel line 144 Warning long unsigned int format, size_t arg (arg 7) dmapool.c kernel_1s10/build/src/drivers/base line 73 Warning size_t format, unsigned int arg (arg 6) dmapool.c kernel_1s10/build/src/drivers/base line 73 Warning passing arg 2 of `__request_region' makes integer from pointer without a cast altera_pio_button.c kernel_1s10/build/src/drivers/char line 212 Warning passing arg 2 of `__release_region' makes integer from pointer without a cast altera_pio_button.c kernel_1s10/build/src/drivers/char line 216 Warning passing arg 2 of `__release_region' makes integer from pointer without a cast altera_pio_button.c kernel_1s10/build/src/drivers/char line 225 Warning comparison of distinct pointer types lacks a cast random.c kernel_1s10/build/src/drivers/char line 1434 Warning comparison of distinct pointer types lacks a cast random.c kernel_1s10/build/src/drivers/char line 1684 Warning unused variable `fhp' svcsubs.c kernel_1s10/build/src/fs/lockd line 58 Warning unused variable `inode' svcsubs.c kernel_1s10/build/src/fs/lockd line 127 Warning size_t format, __kernel_size_t arg (arg 3) nfs2xdr.c kernel_1s10/build/src/fs/nfs line 246 Warning size_t format, __kernel_size_t arg (arg 3) nfs2xdr.c kernel_1s10/build/src/fs/nfs line 391 Warning long unsigned int format, int arg (arg 3) proc_misc.c kernel_1s10/build/src/fs/proc line 276 Warning long unsigned int format, int arg (arg 4) proc_misc.c kernel_1s10/build/src/fs/proc line 276 Warning comparison of distinct pointer types lacks a cast dev.c kernel_1s10/build/src/net/core line 2415 Warning comparison of distinct pointer types lacks a cast dev.c kernel_1s10/build/src/net/core line 2436what is wrong with my operation,and how can I correct it?It is hurry,PLS help me,Thanks very much.    Tony Zhu  hongQing,China
