Out of interest, where did you find those patches?

I found an outdated patch for an older version of xz-utils that didn't work on google and, after a bit more googling found out what exactly the problem was (OS X uses the symbol __MACH__ to indicate it uses the Mach-O binary format, and Hurd uses it to indicate it uses the Mach kernel, or something). So I looked through the breaking files and fixed it myself.

Allan · 2010-01-20 12:52:06

Cool. That explains why I could not find them!

Edit: I changed them for this line as they did not apply for me:

sed -i "s#__MACH__#__OSX__#" xz-$XZUTILS_VER/src/liblzma/check/crc{32,64}_x86.S

Well, my hard work patching was all for naught. sed didn't even occur to me

Haha Well, you pick these things up when you spend too much time on packaging....

I thought it about time to make another tarball:
http://allanmcrae.com/hurd/crosshurd-20100121.tar.gz

New cross compiles: bzip, binutils, fakeroot, gawk, gzip, mpfr, xz-utils, zlib (mostly from Barrucadu)

I left gdbm and db in the "source/devel" folder as I have not actually tested them yet.

Binutils is there, but until I get gcc going I can not test it that easily. It installs some files in funny places but we can fix that building natively. ppl and cloog-ppl should be easy to build and I will tackle gcc and try getting a natively compiling "hello world". I doubt that will occur before Sunday. Once that is done, I will focus on openssl and wget if no-one has beaten me to it...

I'd guess findutils, util-linux-ng, gettext should be fairly easy to package. Try without acl/attr dep for gettext. libarchive and libfetch are BSD projects and compiled readily for linux so I guess they will be nicely portable to hurd too.

Allan, I found some spare time to try Hurd again, but the tarball won't be downloaded, have you relocated it ?

It's OK here .

Ashren · 2010-01-20 20:33:15

With the newest tarball i get the following error right after cross-binutils-build:

make[1]: Leaving directory `/home/regj/hurd/build/cross-binutils-build'

bzip2: Compressed file ends unexpectedly;
    perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
    Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

Perhaps you used the wrong -p or --strip option?

One of your gcc sources is not downloaded properly.

No. That link works for me...

SoleSoul · 2010-01-21 00:46:58

Can you post please a link to a page (or if you want, write it here) describing the actual advantages of the hurd kernel over the linux/bsd/nt kernels?
Everything I found wasn't clear enough or from the developer point of view like here: http://www.gnu.org/software/hurd/hurd/advantages.html
What would a user benefit from it when it would be mature and compatible enough?

Thanks.

It pretty much comes down to the design. Some people think a micro kernel design is better and some prefer a monolithic kernel design. Both designs have their pros and cons. It is hard to find a page which makes a fair comparison of Hurd and Linux, I think a better approach is to understand the concept of both micro kernels and monolithic kernels.

In case you don't know, Hurd is a micro kernel design and Linux/BSD is a monolithic kernel design.

sand_man · 2010-01-21 06:43:50

I believe this is one major benefit of a micro kernel (from SoleSoul's posted link)

It is possible to develop and test new Hurd kernel components without rebooting the machine (not even accidentally). Running your own kernel components doesn't interfere with other users, and so no special system privileges are required. The mechanism for kernel extensions is secure by design: it is impossible to impose your changes upon other users unless they authorize them or you are the system administrator.

Another thing I noticed from reading around on the site, http://www.gnu.org/software/hurd/hurd/faq.html , there seems to be some things you could do without needing root privileges in a micro kernel, unlike linux. I wonder if that would apply to Xorg also. They did state that X is very unusable in Hurd anyway. Maybe a modification is needed?
...I'm just rambling.

you can try

http://www.informit.com/articles/printe … ?p=1180992

which, while still having much from the developer POV, describes some user benefits of a would be 'mature' hurd system.

Barrucadu · 2010-01-25 17:22:33

Allan, I've been busy over the past few days with exams. How's GCC/pacman going?

Allan · 2010-01-26 00:19:06

Not a lot of progress in the last few days. I have been busy with work and Arch Linux...

Barrucadu · 2010-01-26 07:32:56

Ok. Well, I should be able to start doing things again by the weekend.

Barrucadu · 2010-01-31 16:29:05

*prod*

I'm having difficulty with `ppl`, people! Anybody want to give it a go?

I'm currently rebuilding my cross-toolchain, I'll post the error message later. IIRC it's something about libgmpxx.

Allan · 2010-02-01 00:27:40

You do not actually need ppl and cloog-ppl for gcc. They are optional. I ran into issues there so I skipped them. Still can not get gcc to compile either...

Barrucadu · 2010-02-01 00:53:34

Argh, we're frustratingly close

Allan · 2010-02-02 07:44:15

I think I have figured the gcc issues. It turns out cross compiling the gcc c++ compiler is crap for gcc-4.4. And we need g++ support for gmp. I think downgrading to 4.3.x should help.

I have also started reworking the build scripts a fair bit to more closely follow CLFS as the toolchain really needed more care taken to ensure it will work correctly.

Allan · 2010-02-02 08:33:07

Hmm... gcc-4.3 requires a bit of patching... building now so we will see how that went!

Allan · 2010-02-02 13:27:38

GOOD NEWS EVERYONE!

I have managed to get the toolchain completely cross compiled. That means we can start natively compiling soon.

Closely followoing the CLFS approach, I have so far cross compiled these packages to Hurd:

glibc-2.10.1
libpthread-git
zlib-1.2.3 
binutils-2.19.1
gmp-4.3.2
mpfr-2.4.2
ppl-0.10.2
cloog-ppl-0.15.7
gcc-4.3.4
ncurses-5.7
bash-4.1.002
bison-2.4
bzip2-1.0.5
coreutils-8.4
diffutils-2.8.1
findutils-4.4.2
file-5.0.4
flex-2.5.25
gawk-3.1.7
gettext-0.17
grep-2.5.4
gzip-1.3.13
m4-1.4.13
make-3.8.1
nano 2.2.1
patch-2.5.9
sed-4.2.1
tar-1.22
texinfo-4.13a
xz-utils 4.999.9beta
gnumach-git
hurd-git
grub-0.97

That means we only need fakeroot, openssl, libarchive, libfetch to build pacman and have makepkg working and to start actual packaging! (I know there was a script supplied for fakeroot but it needs adjusted...).

Congratulations!

This is great, can't wit to try it out. Great work!
