Subject: undefined reference
Date: Mon, 25 Mar 2002 00:16:04 +0800 [thread overview]
Message-ID: <004501c1d34f$32bda110$0100a8c0@winxp> (raw)
The case is quite complicated.
I am now developing a module. This module need communicate with the kernel.
So I exported a function func(), by using EXPORT_SYMBOL(func). In the header
file, I set "extern int func()".
I also modified the kernel source code, which is inode.c, and insert the
func() and the module header file.
After the above procedure, I use "make bzImage" to build the kernel. At the
compile stage, it does not appear warning message, but it appears in the
linking object stage, which is
fs/fs.o(.text+0x1377d): undefined reference to `func'
How can I solve this issue? Or any parameter for "ld" to avoid checking the
undefined reference?
Thanks.
