Hi,
I am quite new to grub2 anf I find some issue in make of grub2
I modify the hello module by adding a new file a.c, with a function test() in
it.
I call the function test from hello entry point - grub_cmd_hello()
When I do a make, I get the error that
test in hello is not defined
make: *** [moddep.lst] Error 1
I have modified the conf/common.mk accordingly as shown below.
# For hello.mod.
hello_mod_SOURCES = hello/hello.c hello/a.c
CLEANFILES += hello.mod mod-hello.o mod-hello.c pre-hello.o

Could anyone let me know whether I need to do anything more.
