Hi List, I was trying to use minios to implement network frontend driver. When I added gnttab.c, the fowllowing messages appear: [ -e include/xen ] || ln -sf ../../../xen/include/public include/xen # [ -e xenbus/xenstored.h ] || ln -sf ../../../tools/xenstore/xenstored.h xenbus/xenstored.h gcc -fno-builtin -Wall -Werror -Iinclude/ -Wredundant-decls -Wno-format -Wstrict-prototypes -Wnested-externs -Wpointer-arith -Winline -m32 -march=i686 -g -c gnttab.c -o gnttab.o gnttab.c: In function `gnttab_end_access'': gnttab.c:90: warning: implicit declaration of function `printk'' gnttab.c:93: warning: implicit declaration of function `synch_cmpxchg'' gnttab.c: In function `gnttab_alloc_and_grant'': gnttab.c:135: warning: implicit declaration of function `virt_to_mfn'' gnttab.c: In function `gnttabop_error'': gnttab.c:146: warning: implicit declaration of function `ARRAY_SIZE'' gnttab.c: In function `init_gnttab'': gnttab.c:165: warning: implicit declaration of function `set_xen_guest_handle'' gnttab.c:168: warning: implicit declaration of function `map_frames'' gnttab.c:168: warning: assignment makes pointer from integer without a cast make: *** [gnttab.o] Error 1 The code is the same as the posted. Could someone give some help? Thanks a lot! -zheng _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
