>How do you compile and link fs/ntfs.c
I modified i386-pc.mk :%s/minix/ntfs/g
>Can you show a backtrace of the crash?
see attached mkimg.log
I noticed that there are some external unresolved link symbols...
ie. libntfs uses fprintf, calloc, mbrtowc, memcpy etc...
I suppose these will need to be defined in ntfs.o
and libntfs.a is compiled for linux, it will need to be compiled
for grub2. How do I do this? I suppose --no-stdlib
and make equivalents for <stdlib.h>, <ctype.h> etc....

Ok. But I assume you have to add something in order to link it to the
library?

Well, in GRUB we have functions like grub_memcpy, etc.
But the best way to implement NTFS is by writing it yourself. It is
on my todo already, or do you want to do this? I don't think it is
easy and clean to use libntfs. Another thing to consider is its size.

ah, yes indeed...
+ grub_setup_LDFLAGS = libntfs.a
+ grub_emu_LDFLAGS = libntfs.a
ntfs.mod: pre-ntfs.o mod-ntfs.o
-rm -f $@
- $(LD) -r -o $@ $^
+ $(LD) -r -o $@ $^ libntfs.a
$(STRIP) --strip-unneeded -K grub_mod_init -K grub_mod_fini -R .note
-R .comment $@
Would you have suggestions on compile flags needed to compile libntfs
for grub? (now they are -g -O2 -MT -MD -KP -MF )
>I don't think it is easy and clean to use libntfs.
I figure that libntfs was intended to be " a library to avoid code
duplication
and provide access to NTFS to other GPLed programs " therefore
I assume that using this effort would result in the better solution.
>But the best way to implement NTFS is by writing it yourself. It is

I have no intention whatsoever to implement an ntfs driver... providing
the glue between grub and libntfs is/should be a much smaller effort...
Unless you're telling me trying to do this is a lost effort?
>Another thing to consider is its size.
ntfs.mod is 74KB . I don't thinks thats insurmountable...

It looks fine to me.

But would this be the right solution for GRUB?

Personally I don't like it much to link against an external library to
get filesystem support. I would only consider doing such thing when
the filesystem structure changes very often, like reiser4.
One problem is that external symbols are required by the library, many
of which we do not have. Another problem is that the binary gets a
lot bigger.
Okuji has to decide about this, this is not up to me.
>>Another thing to consider is its size.

Most other filesystem modules are between 3 and 7KB.

I don't like, either. External dependencies should be avoided, whenever
possible. Glue code is really painful to maintain.

Yeah, 74KB is too big. It does not fit in the rescue mode. Why does it
become so big?

Hello grub,
I'm trying to compile the attached file, to provide
NTFS support for GRUB2. It's supposed to use libntfs
(http://linux-ntfs.sourceforge.net/).
to compile libntfs, I used
./configure --disable-default-device-io-ops
--disable-gnome-vfs
--enable-really-static
the in config.h, I added
#define printf grub_printf
#undef errno
then "make" in libntfs, which gives me a libntfs.a
Then I tried to compile fs/ntfs.c, which works,
but I then get a crash in
./grub-mkinage -d . -o core.img _chain ntfs ls terminal normal vga
Can anyone advise on this?
