Error Implicit Declaration Of Function ‘create_proc_read_entry’

implicit declaration of function 'create_proc_read_entry' [-Werror=implicit-function-declaration] up vote 6 down vote favorite 1 I'm trying to compile a kernel module on kernel 3.13 and I get this error: error: implicit declaration of function 'create_proc_read_entry' [-Werror=implicit-function-declaration] I google it and did not found any response. Here is the part of the code which refers to this error: #if (LINUX_VERSION_CODE < KERNEL_VERSION(2,6,24)) proc = proc_net_create(KAODV_QUEUE_PROC_FS_NAME,

Error Implicit Declaration Of Function ‘strnicmp’

0, kaodv_queue_get_info); #else proc = create_proc_read_entry(KAODV_QUEUE_PROC_FS_NAME, 0, init_net.proc_net, kaodv_queue_get_info, NULL); #endif if (!proc) { printk(KERN_ERR "kaodv_queue: failed to create proc entry\n"); return -1; } Can I get help ? I really don't know what is wrong. It might be the kernel 3.13 which needs a patch. I read somewhere (on KERNEL 3.10) that the kernel needs patch. Can anyone show me where can I get the 3.13 kernel patch to eventually fix the problem. Thanks c linux linux-kernel kernel-module share|improve this question asked Sep 9 '14 at 13:53 scof007 751212 1 The error is because you are not including explicitly the header that declares the function and the compiler is 'including' implicitily for you and this throws a warning. The flag '-Werror' is making the compiler treats the warning as an error. Try adding: #include –braindf Sep 9 '14 at 14:17 @braindf: We not make this an answer, as it is the answer. –alk Sep 9 '14 at 14:23 Also: create_proc_read_entry is a deprecated function. lkml.org/lkml/2013/4/11/215 –braindf Sep 9 '14 at 14:24 possible duplicate of implicit declaration of function 'create_proc_entry'

Yes. Include the correct prototype error implicit declaration for func_name in a header and include that header in fileA.c santosh, Jun 17, 2008 #2 Advertisements Richard Tobin Guest In article <>, DanielJohnson <> wrote: >I know that I have to include the file in fileA.c but the library in >which I am working on is clean, i.e. there are no cross includes like >that. Why do you think it is "unclean" to include the necessary header? If your program has a structure you consider unclean, then restructure the program. Don't try to hide the dirtiness by not including the necessary headers. -- Richard -- In the selection of the two characters immediately succeeding the numeral 9, consideration shall be given to their replacement by the graphics 10 and 11 to facilitate the adoption of the code in the sterling monetary area.
