[Buildroot] Bootloaders

[Buildroot] Bootloaders

[Jason Valenzuela]

Trying to get my first root fs ready to boot and I can't seem to get any 
of the bootloaders to compile.

Grub complains about not finding a specific patch on the debian ftp site.

syslinux complains while building to the tune of
"as: option '-alternate' doesn't allow an argument." This is the 'as' 
that is provided in my default i486 slackware host system.

U-boot dies with *** No rule to make target `_config'.

pxelinux I haven't tried as my target host isn't going to be on a network.

Am I missing something stupid?

Thanks,
Jason Valenzuela

Jason,

I am new to Buildroot as well. I have successfully created an x86 target
with Grub as the bootloader. I was wondering if the error you're getting
says something about not being able to resolve the debian ftp site? Are you
able to even download grub from the correct repository first? I just want to
know if it's a compiling problem or a problem with retrieving grub. If it's
the latter than the problem lies within the actual Makefile, in that the
repository is broken and you need to change the path for your development
system to go grab it from.

I wish I could help with your U-boot problem, but for now I am struggling
just to get an ARM build done so I can test it out on QEMU (an emulator
which I can use to serve as my ARM bootloader). I will soon need to build
u-boot as well so if anyone responds to your questions it would be helping
me out as well in the future.

Ok so the buildroot make process it trying to pull a .diff from the 
debian site that doesn't exist. I found that this is a known problem in 
buildroot's bug tracking system. I tried two things, first I found the 
actual .diff elsewhere, downloaded it into the dl directory and tried a 
make. That crashes with complaints about uClibc being built without 
large file support. Enabling large file support in uClibc's make 
menuconfig also doesn't build.

Next I tried to modify the grub.mk so that it downloads a slightly newer 
.diff from the debian site. Was a real long shot and of course didn't 
work either.

So now I'm trying to simply build grub on my host system and see if I 
can go from there.

Jason,

I had the same problem with the build process breaking and complaining about
uClibc not having LFS support. There are some things you need to make sure
you do. First of all, go into your Buildroot .config and make sure the LFS
flag is toggled (within the toolchain submenu). Now change the uClibc
.config LFS flag, which you seem to have already done. Do a make clean in
both the kernel and uClibc directories (to make sure any junk binaries are
cleaned out before continuing the build), then go back to the buildroot
directory and make. That should take care of the LFS problem.

As for the grub.mk modification, can you post the exact error you get with
the debian site not being able to be resolved? I can cross reference that
with my own grub.mk and see where I downloaded grub from.

Excuse me, I meant to say, make sure you do a "make clean" in both uClibc
and the main buildroot directory before doing continuing with "make" in your
Buildroot directory. There is no need to do a make clean for the kernel
since you didn't modify anything in it. Sorry about that.

wget fails to get 
http://ftp.debian.org/debian/pool/main/g/grub/grub_0.97-35.diff.gz

Fails with a 404 Not Found.

If I ftp manually to that site, the file is indeed not there.

Well I checked my x86 project and I have grub 0.97-35. I haven't touched
that project since April, so they must have removed 35 from this repository
pretty recently. I find that really annoying that they only keep the latest
version up there.

Anyway, I am very surprised your build isn't working with version 38. I
remember having the same problem with grub because version 0.97-33 wasn't
available! So I changed the .mk file to direct it to 35 and it worked. I see
that version 27 is up there still... can you try getting that one and see
what happens?

I found the -35 patch with google and am currently recompiling uClibc as 
you directed. If that builds and grub too, I can see if the -27 builds.


I noticed that there were other grub patches within the target/x86/grub 
directory. Perhaps those don't work correctly with the -38 patch.

Ok, thanks for the help so far. Got uClibc and grub to build ok.

Some booting issues:

I'm looking to use this to boot from a compact flash. I've partitioned 
and created an ext2 file system on the CF card. I mounted this partition 
and untarred the root file system onto the CF. I've copied the kernel 
from binaries/PROJECT_NAME/ to /boot in the CF file system.

Now I'm kind of fuzzy on how to get grub to setup on it. The card shows 
up as /dev/hdc with the only partition being /dev/hdc1, which seems 
fine. If I chroot onto it and run grub, when I try and issue a root 
(hd2,0) I get 'Error 21: Selected disk does not exist'.


Thanks,
Jason Valenzuela

Can you post your menu.lst file? I'm mainly interested to see what's in the
/kernel line.

Should I have such a file at this point? I'm still working on the host 
system with the CF card in the PCMCIA socket, not booting the target yet.

[Buildroot] malloc/rpl_malloc

[Jason Valenzuela]

I'm trying to compile some packages of my own and am coming up with some 
problems at link time with the malloc function. According to the uclibc 
FAQ, MALLOC_GLIBC_COMPAT should be enabled in order for the configure 
script not to define malloc() to rpl_malloc(). I went to the 
toolchain_build_ARCH/uClibc-0.9.29 and did a 'make menuconfig'. This 
option under 'General Library Settings->Malloc returns live pointer for 
malloc(0)' was indeed enabled, causing me to believe that the uclibc in 
my buildroot toolchain is already correctly set.

Now going back to the build_ARCH/MY_PACKAGE directory and checking the 
config.h, HAVE_MALLOC has been defined as 0 and the results in 
config.log shows that the configure script didn't think malloc() was 
compatible with the GNU libc version.
