Still having a problem building elks kernel

Still having a problem building elks kernel

[Dieter R Kedrowitsch]

With the help of a few folks on here I've gotten pretty far with 
building the elks kernel, but it looks like I have one more problem 
before the image will build.  It seems there is a syntax error in the 
makefile ld86. 

Has anyone else run into this?

Sorry, I meant to get back to you sooner. I run into the exact same
thing with Debian, but not Arch Linux.
Here's the last little bit from Make on Arch which seems to work (I
don't have the means to actually test it though)

as86 -0  -o boot/crt0.o boot/crt0.s
(cd ../.. ; ld86 -0 -i   \
                -t -M -o arch/i86/boot/system \
                arch/i86/boot/crt0.o arch/i86/boot/crt1.o \
                init/main.o kernel/kernel.a fs/fs.a lib/lib.a
net/net.a fs/minix/minixfs.a arch/i86/kernel/akernel.a

arch/i86/drivers/block/blk_drv.a \
                > System.tmp ; \
                sort -k4 System.tmp > System.map ; rm -f System.tmp )
tools/build boot/bootsect boot/setup boot/system > boot/Image
Root device is (3, -128)
Boot sector 512 bytes.
Setup is 1596 bytes.
System is 117788 B (58784 B code, 7728 B data and 51276 B bss)
System is 66544
make[2]: Leaving directory `/home/harley/Source/elks-project/elks/arch/i86'


Obviously the ld86 is failing in Debian/Ubuntu, but like I said, I
haven't looked into why yet other then the fact that it looks like "-t
-M -o arch/i86/boot/system \" isn't in the Debian/Ubuntu's ld86's
command for some reason...

Well, I was partially wrong. It looks like it does have the same ld86
command, but the Debian/Ubuntu one is returning an empty boot/Image
file whereas on Arch it's returning a 68K file. But that's without
looking too far into it....

Re: Still having a problem building elks kernel

I just created a new VM and installed Arch Linux last night.  I'll try
installing the bcc x86 packages this evening and cross my fingers that
this distro does the trick.  I wonder what the difference is?

For what it is worth, it builds OK under Gentoo Linux. The only problem is that 
the output is somewhat broken :-(

Looks like I'm having the same problem here.  I tested the build I
made in Ubuntu 9.10 i386, on a VMware Workstation 7 virtual host and
my output looks VERY similar.  See attached screenshot...

I'll test this tonight on my 10MHz XT clone and see if it behaves
better on an actual PC.

Ideas, comments?

Re: Still having a problem building elks kernel (nospam: message 15 of 20)

From what I remembered you only seem to get this bug if you select BIOS for the 
console which is what I require since I have no video support,

Good luck,

Oh, I think I know what the issue may be. I just tested building Elks in a 32
bit Ubuntu chroot (much quicker then a VM.) It seems something that there
are assumptions that the environment is 32 bit. I'd guess it's probably
./arch/i86/tools/build.c that's making assumptions someplace it shouldn't
about the size of int, char, long, etc. For now I guess setup a 32 bit system
(VM or chroot should both work fine), or if you're feeling ambitious, you can
try tackling the issue in that's probably in the file I mentioned.

Re: Still having a problem building elks kernel

[Dieter Kedrowitsch]

Ah-ha!  That would make sense!  I believe I have the 32 bit ISO for
the latest Ubuntu, I'll give that a shot!

Ok!

By using Ubuntu 9.10 i386 and applying the following changes to a
fresh download of the elks-0.1.3.tar.gz before doing make config, make
dep, make Image:

edit /arch/i86/boot/setup.S line 588 remove () from around CONFIG_CPU_80386
edit /arch/i86/drivers/char/Keymaps/mkcfg change "sort +1f" to "sort -f"

I was able to get 95% there.  It still errors out during linking of the image.

However, by manually linking using the sample from Harley...

cd ../.. ; ld86 -0 -i \
-t -M -o arch/i86/boot/system \
arch/i86/boot/crt0.o arch/i86/boot/crt1.o \
init/main.o kernel/kernel.a fs/fs.a lib/lib.a net/net.a

arch/i86/drivers/block/blk_drv.a \
> System.tmp ; \
sort -k4 System.tmp > System.map ; rm -f System.tmp

...then allowing make Image to finish, I was successful!

So, why does make Image try to link differently then Harley's example?
 Does Arch vs Ubuntu really have anything to do with it?

Nope, I selected DIRECT for that option, not BIOS.

It looks like every time a number is displayed it adds a bunch of 0's
in front of it, almost as if a variable is cast incorrectly
somewhere...
