I'm confident Hurd will win.

Here is my attempt at a (still not working...) cross-compiler: http://allanmcrae.com/packages/cross-i686-pc-gnu.tar.gz . The build order are at the top of all the PKGBUILDs.

The issue is with the first pass of glibc. It is known not to work and so you need to force the build, but there are missing files that are quite essential for the rest of the cross compiling. Specifically crt1.o which the cross-ld wants. So... the glibc build appears to be more broken than the known amount of broken! That means compiling libpthreads and the next pass of gcc fails badly.

I will not be able to look into this further until the weekend (hint... hint... )

Someone should try glibc-2.7 with these patches: http://www.schwinge.homeip.net/~thomas/ … c-patches/ . It is flagged as "known to work"...

Edit: or pull everything starting with "hurd-i386" from debian: http://patch-tracker.debian.org/package … exp1-0exp1

Edit: and remove "--without-tls" from the configure line.

I'll have a look after school

Or maybe even in school, I have a couple of free periods…

Cool. As a warning, patching glibc using all (31!!) hurd patches from Debian makes things worse...

Edit: as does applying the entire patch-set.

I guess trying glibc-2.7 with those patches is the way to go for building a cross compiler. The key point is to have a file called crt1.o in /usr/lib/cross-i686-pc-gnu/lib.

flamelab · 2010-01-06 09:21:55

Trying a different one, like eglibc, like Debian does ? Would that help ?

Very interesting project indeed

Barrucadu · 2010-01-06 14:38:43

Woo, school finished early due to the snow!

Barrucadu · 2010-01-06 22:49:48

I've got glibc 2.7 to build with those patches, but it's missing stubs-32.h and without that libpthread won't compile. Google isn't being much help here.

edit: moving my local copy of stubs-64.h to /usr/lib/cross-i686-pc-gnu/include/gnu/stubs-32.h makes it compile; not sure if it'll work properly though. If it appears in the package after the second pass of glibc I'll rebuild libpthread and gcc just to be safe.

edit 2: Oh, no, it didn't work. It just died later in the compilation process and I didn't notice.

I have been try to make this work as well.
Does it fail with "ld: can not find libcrt.a".
If so remove the reference from "/usr/lib/cross-i686-pc-gnu/lib/libc.a", I just added "sed -i 's/libcrt.a //' $pkgdir/usr/lib/cross-i686-pc-gnu/lib/libc.a" to the bottom for the glibc PKGBUILD.
But still it fails later complaining that the c compiler cannot create executables. Which lead me to notice that gcc-pass1 can't either, and now I'm back where i started almost.

Just touching that file should be fine... using the 64bit version in place of the 32bit one is probably not a good thing!

Correct. gcc (pass 1) will not be able to create executables until the needed libraries from glibc are installed. That is why the first gcc build is very minimal and should have been hopefully enough to build enough of glibc to finish the process.

Looking at the know to work package versions, perhaps we should downgrade binutils to 2.19 along with glibc to 2.7 with all those patches. I will try that tomorrow.

Barrucadu · 2010-01-07 21:52:40

I'm still not able to get libpthread to compile after glibc pass one.

Same.
I just tried with binutils 2.19 and glibc 2.7 and I still can't get it to work. With glibc 2.7 it compiles crt1.o which 2.11 and 2.10 didn't, but it still can't build libpthread.

Allan · 2010-01-07 22:36:43

Can someone please post the PKGBUILD for glibc-2.7 with those patches? I am going to look at this today but I am also feeling lazy...

This one uses the debian patches, but it fails fairly quickly, so its more just a reference.

For me glibc 2.7 with or without the other patches doesn't seem to make much difference.

Barrucadu · 2010-01-08 07:46:11

I would imagine it fails more quickly because those patches are for eglibc 2.11, not glibc 2.7

WOO!

allan@arch ~/tmp/hello

./hello: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Hurd 0.0.0, not stripped

I will see if I can do the same thing in PKGBUILD format now... update soon!

Edit: it appears the whole issue was the cross build process using the wrong ld at various stages. I will just create a script to install a cross compiler somewhere on your system that is not in your path and we can use this. Why make things more complicated than they are...

Allan · 2010-01-08 14:05:14

Here we go... http://allanmcrae.com/scripts/crosshurd.sh . Set ROOT and HOST at the top of the script as appropriate.

TODO
- try updated gcc (running now with gcc-4.4.2)
- build for i686 target (requires using CFLAGS, see note in gcc_pass1).
- newer binutils (need to patch glibc to detect).
- newer glibc....

Edit: I noticed a couple of errors in the script, but it is late and I need sleep. Expect a new version tomorrow.

bobdob · 2010-01-08 14:56:24

I think I might have just built a working glibc2.7

$ cat hello.c 
#include <stdio.h>

int main ()
{
    printf ("hello world\n");
    return 0;
}
$ i686-pc-gnu-gcc -o hello hello.c

                 from hello.c:1:

Here is the PKGBUILD I use. I copied the BUILD_CC, CC, AR, and RANLIB from clfs and added LD.

Now to see if libpthreads builds

Edit: Just built cross-i686-pc-gnu-libpthread and it worked.

Edit2: But gcc pass 2 doesn't

Excellent, I'll start playing with the script immediately.

Wouldn't it be easier to bootsrap from e.g. Debian? Build some initial packages, install them into a chroot etc..
