The LFS book does not say to create gcc-build before unpacking the source tarball. Seems you need to take a close look at page 5.3, in particular the very last "Note" there - it says that you are to unpack the source tarball, cd into the created directory, *then* follow the instructions on the page. 2. The gcc-build directory is not in $LFS/sources, so that means that either you have become root (or used sudo) to create it, or you have chowned/chmodded $LFS, neither of which you should be doing. If you did this because you were getting permissions errors attempting to create gcc-build, see #1 above that will solve that issue. Also, do not use root/sudo at any point in Chapter 5 until you are told to, and if you did chown/chmod $LFS, change it back (owned by root, 755 permissions). 3. You forgot --prefix on that configure command. That would explain the permission errors on make install. I don't recognize the particular error you are getting and don't know whether it's related to any of the above issues, but the fact that you did miss those is an indicator that you do need to read a bit more closely. The compile errors you are getting are likely due to some other detail you've overlooked. Remove the GCC source and build dirs and try again, this time reading more slowly and carefully. If that still doesn't work, rm -rf /tools/* and go back to the beginning of Chapter 5. > > If I try to do a "make install", I get the following: > > l...@carina:/mnt/lfs/gcc-build/gcc-4.4.3$ make install > make[1]: Entering directory `/mnt/lfs/gcc-build/gcc-4.4.3' > /bin/bash ./mkinstalldirs /usr/local /usr/local > make[2]: Entering directory > `/mnt/lfs/gcc-build/gcc-4.4.3/host-i686-pc-linux-gnu/fixincludes' > rm -rf /usr/local/libexec/gcc/i686-lfs-linux-gnu/4.4.3/install-tools > /bin/bash ../.././fixincludes/../mkinstalldirs > /usr/local/libexec/gcc/i686-lfs-linux-gnu/4.4.3/install-tools > mkdir -p -- /usr/local/libexec/gcc/i686-lfs-linux-gnu/4.4.3/install-tools > mkdir: cannot create directory `/usr/local/libexec': Permission denied > make[2]: *** [install] Error 1 > make[2]: Leaving directory > `/mnt/lfs/gcc-build/gcc-4.4.3/host-i686-pc-linux-gnu/fixincludes' > make[1]: *** [install-fixincludes] Error 2 > make[1]: Leaving directory `/mnt/lfs/gcc-build/gcc-4.4.3' > make: *** [install] Error 2 Obviously make install won't work if make has errors. > > > Can anyone shed some light on this for me? > > Thanks in advance. > > John Stephens > Bruce is right about gawk, and more generally that you have missed a page about Host System Requirements.

Bk6.6Ch6.9 glibc compile stopped with `__stack_chk_guard'
Hi All, I've reached LFS Bk6.6 Ch6.9 "Glibc-2.11.1". I've followed the book pretty much to the letter. My variance from book 6.6 consist of: /mnt/lfs/source - source files downloaded into this directory. /mnt/lfs/scratch - source files un-tar'ed and built in this directory. script files - to reduce opps's while cutting and pasting lines to execute i placed them in script files in order to ensure correct transcription from the book. I would then execute the script and verify that it did what it was suppose to. Compilation is on/for an Intel Pentium 4.

Problems with HAL
I built HAL, and during the compile received some errors that appeared to be related to the building of the documentation, so I didn't worry about it. I installed it, along with the startup script and thought things were ok. Now I find its not running. The only way to start it is to specify daemon=no.

Unable to compile GCC-4.4.3, Pass 1
Greetings,
I am attempting to build my first LFS project, but can't see to get past the
GCC, pass 1 compile. FWIW, Linux is not new to me. I have had an interest
in working through a LFS project for several years, and now I actually have
some time to do it.
I suspect I have a configuration setting gone wrong, however I am unable to
see what is going wrong.
I have a Ubuntu 9.10 host (AMD Athlon CPU, 1G memory). I've defined an lsf
user and have a separate 50G partition mounted at /mnt/lfs. All the
suggested symlinks are in place.
My lfs user environment is:
l...@carina:~$ env

LC_ALL=POSIX

At this point, I believe all is OK. GCC is then unpacked in $LFS/gcc-build,
mpfr-3.4.3 and gmp-5.0.0 are unpacked into $LFS/gcc-build/gcc-4.4.3 as mpfr
and gmp respectively.
GCC is then configured using:

OK then. Are you at the test phase? That is doing section 8.4.3. Testing the Configuration. If so, what seems to be happening is that grub-install is not creating the /boot/grub/core.img file properly. grub-install is a script. You might try hacking that script around line 312 to see what the value or $modules is for your installation. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Re: Simple OS Support
i have chek it already, but most examples are not working i think the our
system is not capable to run that code or something like that. finally i
found an guide for it but i didn't work. here the guide
LBA HDD Access via PIO
Every operating system will eventually find a need for reliable, long-term
storage. There are only a handful of commonly used storage devices:
-
Floppy
-
Flash media
-
CD-ROM
-
Hard drive
Hard drives are by far the most widely used mechanism for data storage, and
this tutorial will familiarize you with a practical method for accessing
them. In the past, a method known as CHS was used. With CHS, you specified
the cylinder, head, and sector where your data was located. The problem with
this method is that the number of cylinders that could be addressed was
rather limited. To solve this problem, a new method for accessing hard
drives was created: Linear Block Addressing (LBA). With LBA, you simply
specify the address of the block you want to access. Blocks are 512-byte
chunks of data, so the first 512 bytes of data on the disk are in block 0,
the next 512 bytes are in block 1, etc. This is clearly superior to having
to calculate and specify three separate bits of information, as with CHS.
However, there is one hitch with LBA. There are two forms of LBA, which are
slightly different: LBA28 and LBA48. LBA28 uses 28 bits to specify the block
address, and LBA48 uses 48 bits. Most drives support LBA28, but not all
drives support LBA48. In particular, the Bochs emulator supports LBA28, and
not LBA48. This isn't a serious problem, but something to be aware of. Now
that you know how LBA works, it's time to see the actual methods involved.
To read a sector using LBA28:
1.
Send a NULL byte to port 0x1F1: outb(0x1F1, 0x00);
2.
Send a sector count to port 0x1F2: outb(0x1F2, 0x01);
3.
Send the low 8 bits of the block address to port 0x1F3: outb(0x1F3,
(unsigned char)addr);
4.
Send the next 8 bits of the block address to port 0x1F4: outb(0x1F4,
(unsigned char)(addr >> 8);
5.
Send the next 8 bits of the block address to port 0x1F5: outb(0x1F5,
(unsigned char)(addr >> 16);
6.
Send the drive indicator, some magic bits, and highest 4 bits of the
block address to port 0x1F6: outb(0x1F6, 0xE0 | (drive << 4) | ((addr >> 24)
& 0x0F));
7.
Send the command (0x20) to port 0x1F7: outb(0x1F7, 0x20);
To write a sector using LBA28:
Do all the same as above, but send 0x30 for the command byte instead of
0x20: outb(0x1F7, 0x30);
To read a sector using LBA48:
1.
Send two NULL bytes to port 0x1F1: outb(0x1F1, 0x00); outb(0x1F1, 0x00);
2.
Send a 16-bit sector count to port 0x1F2: outb(0x1F2, 0x00); outb(0x1F2,
0x01);
3.
Send bits 24-31 to port 0x1F3: outb(0x1F3, (unsigned char)(addr >> 24));
4.
Send bits 0-7 to port 0x1F3: outb(0x1F3, (unsigned char)addr);
5.
Send bits 32-39 to port 0x1F4: outb(0x1F4, (unsigned char)(addr >> 32));
6.
Send bits 8-15 to port 0x1F4: outb(0x1F4, (unsigned char)(addr >> 8));
7.
Send bits 40-47 to port 0x1F5: outb(0x1F5, (unsigned char)(addr >> 40));
8.
Send bits 16-23 to port 0x1F5: outb(0x1F5, (unsigned char)(addr >> 16));
9.
Send the drive indicator and some magic bits to port 0x1F6: outb(0x1F6,
0x40 | (drive << 4));
10.
Send the command (0x24) to port 0x1F7: outb(0x1F7, 0x24);
To write a sector using LBA48:
Do all the same as above, but send 0x34 for the command byte, instead of
0x24: outb(0x1F7, 0x34);
Once you've done all this, you just have to wait for the drive to signal
that it's ready:
while (!(inb(0x1F7) & 0x08)) {}
And then read/write your data from/to port 0x1F0:
// for read:
for (idx = 0; idx < 256; idx++)
{
tmpword = inw(0x1F0);
buffer[idx * 2] = (unsigned char)tmpword;
buffer[idx * 2 + 1] = (unsigned char)(tmpword >> 8);
}
// for write:
for (idx = 0; idx < 256; idx++)
{
tmpword = buffer[8 + idx * 2] | (buffer[8 + idx * 2 + 1] << 8);
outw(0x1F0, tmpword);
}
Of course, all of this is useless if you don't know what drives you actually
have hooked up. Each IDE controller can handle 2 drives, and most computers
have 2 IDE controllers. The primary controller, which is the one I have been
dealing with thus-far has its registers located from port 0x1F0 to port
0x1F7. The secondary controller has its registers in ports 0x170-0x177.
Detecting whether controllers are present is fairly easy:
1.
Write a magic value to the low LBA port for that controller (0x1F3 for
the primary controller, 0x173 for the secondary): outb(0x1F3, 0x88);
2.
Read back from the same port, and see if what you read is what you wrote.
If it is, that controller exists.
Now, you have to detect which drives are present on each controller. To do
this, you simply select the appropriate drive with the drive/head select
register (0x1F6 for the primary controller, 0x176 for the secondary
controller), wait

Are you asking how to use the BIOS INT 13 services, or possibly how
to program the disc interface chips themselves directly?
If so, then I regret to tell you that both of those are outside the
purview of this echo. I'm sure there are some here who might be
able to help. I've done direct disc I/O using both BIOS, and direct
chip programming for floppies and for Western Digital hard drive
controller chips, though those controller chips are now obsolete.
However, if you're doing homework, or a class project, then I think
you'll learn a lot more if you first research it some yourself, then
post pointed direct questions where you have problems after making
some progress.
This would not be the echo for that, though.

My understanding is that should have worked. Of course, the search line
is not used by LFS. I'd remove it just for clarity.

What happens if you move the set root=(hd0,15) outside the menuentry?

I'm not sure what you mean by rescue shell. Can you elaborate?

Yes, that makes sense. I don't know if that is necessary. I'd think
that ext2 was built into the image loaded at sectors 1-62, where sector
0 is the MBR.
Are you using grub-1.98?

My reading was that it didn't. If you look at my original post I had
|# sda7 LFS-6.6-rc2 pure64
|menuentry "LFS-6.6-rc2 pure64 2.6.33 (sda7)" {
| insmod ext2
| set root=(hd0,15)

| linux /vmlinuz-2.6.33-sda7 root=/dev/sda7
video=radeonfb:1024x768...@70 ro
|}
Is that *not* what the book suggests for root= in my case ? In any
case, grub didn't get that far, it was in the rescue shell, not the regular
grub shell.
And it was the *prefix* hd(0,15)/boot/grub that was the problem - as
I said, I've still no idea where prefix is set.
/me scratches his head a lot, and rereads section 8.4. All I can see is
'default root setting - guessed' and the note beneath it, telling me the
default root will be used if a 'set root' instruction is not found in
grub.cfg. I can't see any reference to *how* to alter the default root,
but since it showed up as root=hd(0,15) when I ran 'set' in the rescue
shell, I believe it was already correct.
Also, isn't 'insmod ext2' going to be redundant in grub.cfg on an ext2+
filesystem ? If grub can't read an ext2fs, it won't be able to read
grub.cfg.

A nit, but nits are important in this context, shouldn't that be
/dev/sda16 ? Or did I miss something?
