Heyho guys!
I'm sorry if I didn't RTFM somewhere but I just couldn't find _any_
information on how to correctly add/patch own modules into the grub
1.99. The problem:
1. mymod.c depends on a function in biosdisk.c
Avoid this as much as possible. Biosdisk is arch-specific, use generic
disk functions.
2. mymod.c includes the biosdisk.h header correctly I suppose
3. I patched grub-core/Makefile.core.def with
module = {
name = mymod;
common = mymod/mymod.c;
enable = biosdisk;
enable=i386_pc; not biosdisk
};
4. I patched grub-core/Makefile.core.am with basically a copy from the
hello.c module stuff (although I should probably take the arch
dependend definitions from biosdisk mod? but I'm building i386 so it
should work any way?)
Don't touch this file. Just rerun ./autogen.sh
5. ./configure&& make works as expected for another module which
doesn't include a foreign function.
6. For mymod.c I receive
mymod/mymod.c:68: error: implicit declaration of function
'grub_biosdisk_get_diskinfo_standard'
This function is static ("private"). Moreover it's for very old C/H/S
addressing.
Looks like you're going the wrong way. Can you detail what's your end goal?
which is of course in biosdisk.c. Now my question: How do I solve this
mystery on a code/patch base? ;) I know that I can add the biosdisk.c
to the common code functions, but that shouldn't be necessary, huh? I
thought that enable = biosdisk would do the trick with linked
functions, but well... maybe you could shed some light on it.
Dependencies are tracked automatically.
Cheers
Robert
