Hi All I am trying to resolve the problem of EXPORT_SYMBOL. I have raised this question on newbies kernel list but no one replied. Hence I am posting it here. I am using kernel 2.4.18-14. Below is the listing of a simple test code.
************************************** /*main.c*/
#include <linux/kernel.h> #include <linux/module.h>
#if CONFIG_MODVERSION == 1 #define MODERVSION #include <linux/modversions.h> #endif
int print_func() { printk("Entry point.\n"); return 0; }
EXPORT_SYMBOL(print_func);
int init_module() { print_func(); return 0; }
void cleanup() { printk("End of story.\n"); }
********************************************
******************************************** /*Makefile*/
export-objs := main.o CC=gcc MAKE = make KERNELDIR = /usr/src/linux-2.4.18-14 MODCFLAGS := --save-temps -Wall -D__KERNEL__ -DMODULE -DLINUX -DMODVERSIONS
main.o: main.c $(CC) $(MODCFLAGS) -I$(KERNELDIR)/include -c main.c
clean: rm -fr *.o *.i *.s
***********************************************
And on compiling the error is as follows...
gcc --save-temps -Wall -D__KERNEL__ -DMODULE -DLINUX -DMODVERSIONS -I/usr/src/linux-2.4.18-14/include -c main.c main.c:15: parse error before "this_object_must_be_defined_as_export_objs_in_the_Makefile" main.c:15: warning: type defaults to `int' in declaration of `this_object_must_be_defined_as_export_objs_in_the_Makefile' main.c:15: warning: data definition has no type or storage class
The error says export_ojbs must be defined. As you can see I have already defined them in the Makefile.
Pleaes help. I am kind of stucked in my project.
Thanks in advance.. Dp
