GMP GCC C++ Hurd cross-build failure on core-updates

GMP GCC C++ Hurd cross-build failure on core-updates

[zamfofex]

[-- Attachment #1: Type: text/plain, Size: 1945 bytes --]

Hello, Guix! I have been trying to update the Hurd packages to their latest commits in the hopes that I can eventually get networking with netdde functioning.

In <https://issues.guix.gnu.org/51770>, I got something that seemed to be working at first (at least it progressed farther than the status quo at the time), but eventually I got an error that seemed related to Mig, which I had not updated in that patch set.

Updating Mig required a more recent glibc than what was available in Guix at the time, so I worked on <https://issues.guix.gnu.org/54832> to update glibc.

Now that the recent glibc is on core-updates, I picked up my work once again. I updated the packages to the latest commits, and updated Mig! However, I ran into an issue while trying to build a system image. The issue is that GMP fails to cross‐compile during the ‘configure’ phase becase the cross‐compiling ‘g++’ is not functional.

When checking whether ‘g++’ can compile executables during ‘configure’, ‘g++’ is unable to link the executables because some ‘pthread_*’ symbols required by libstdc++ are missing from libc. And when checking using ‘readelf’, they are indeed missing from the cross‐built libc, which instead contains similar ‘__pthread_*’ symbols.

I don’t know for sure what the issue is, but I highly suspect libstdc++ is being compiled against the native glibc headers, rather than the cross‐built glibc headers like it should.

Note: Currently, trying to cross‐build packages from core‐updates for the Hurd will fail while compiling glibc, since the Hurd package is too outdated for that version of glibc.

I’ll attach a diff (for core-updates) with the updated Hurd packages to this email. To verify the behavior I’m describing, try running:

- - - - -
./pre-inst-env guix build --target=i586-pc-gnu gmp
- - - - -

Any kind of assistance would be appreciated! Thanks in advance.

I am way out of my depth here, but would it matter that on the hurd
pthread is not in glibc?

Hello!

Nice!

> Now that the recent glibc is on core-updates, I picked up my work once again. I updated the packages to the latest commits, and updated Mig! However, I ran into an issue while trying to build a system image. The issue is that GMP fails to cross‐compile during the ‘configure’ phase becase the cross‐compiling ‘g++’ is not functional.

Could you paste the command you used and the tail of the build log?

I tried this:

   guix time-machine --branch=core-updates -- build --target=i586-pc-gnu gmp 

… but there are too many missing substitutes at this point.  :-)

We still need ‘shepherd-0.8’ here.

Thanks,

When trying that exact ‘guix time-machine’ command, it fails while building glibc, though. (As I had said, I think the ‘hurd’ package is too outdated by now).

I need to apply the patches I sent as attachment last email, and only then I can get to a position where I can even try to build GMP.

I can paste the glibc build log at the end of this email (as even just the tail with relevant errors is a bit too long). I’m also going to send the full logs (glibc’s and GMP’s) as attachments.

Unfortunately, it seems to produce an error for me when trying to use ‘guix system image’. It seems to be because the latest Shepherd package is added to ‘%base-packages/hurd’, I think. The error I get is as follows:

- - - - -
guix system: error: profile contains conflicting entries for shepherd
guix system: error:   first entry: shepherd@0.9.2 /gnu/store/6969ddldrqzvla8yfxlxq00hwkfvwfhs-shepherd-0.9.2
guix system: error:   second entry: shepherd@0.8.1 /gnu/store/wqrshkkkd2ydpd8bxiyc37w574ivbdn7-shepherd-0.8.1
hint: You cannot have two different versions or variants of `shepherd' in the same profile.

At any rate, here are the glibc build logs, as I mentioned above:

It looks as if libstdc++.so lacked libpthread.so from its dependencies
(DT_NEEDED).

What does this say:

  objdump -x \

Looking at this, glibc now has ‘const’ qualifiers for the ‘uids’ and
‘gids’ parameters:

--8<---------------cut here---------------start------------->8---
kern_return_t
_S_msg_del_auth (mach_port_t me,
		 task_t task,
		 const_intarray_t uids, mach_msg_type_number_t nuids,
		 const_intarray_t gids, mach_msg_type_number_t ngids)
--8<---------------cut here---------------end--------------->8---

This comes from this glibc commit:

  commit 0eb230ccceee70c4b5d2a75807d2189aa4ed6e7c
  Date:   Sun Jan 16 18:28:40 2022 +0000

      hurd: Make RPC input array parameters const

      This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server
      side")

My guess is that you’re running a version of MiG that’s older than
cf4bcc3f1435 (MiG commit), and thus it generates stubs (such as the
‘msg_server.h’ file mentioned in the error message above) that lack
those ‘const’ qualifiers.

If that reasoning is good, updating MiG should fix it.

HTH,
Ludo’.

GMP GCC C++ Hurd cross-build failure on core-updates

[Nathan Dehnel]

You could try seeing what they're doing here to cross-build
https://github.com/flavioc/cross-hurd
It worked last time I ran it (which was admittedly a while ago)

Hi,

The problem is probably that you need to add --enable-add-ons=libpthread to
configure when building first version of cross-glibc. This is to obtain weak
references when building libcstd++ of cross-gcc:

nm --dynamic /cross-tools/lib/libstdc++.so.6.0.30|grep pthread
...
w __pthread_key_create
w pthread_key_create
w pthread_key_delete
...

Then that build of cross-gcc will succeed in building the Hurd version of
libstdc++ etc.
nm --dynamic /tools/lib/libstdc++.so.6.0.30|grep pthread
<same as above>

The problem is due to that with recent versions of glibc libpthread is included
for Linux, but not for Hurd.

Note that don't issue autoreconf gcc (in my case 12.2.0) unless you have only
autoconf2.69 installed (or what is needed for your version of upstream gcc).

My scripts to cross-build Hurd on Debian/GNU Linux: hurd-cross (hurdX) will soon
be published on Savannah under the Hurd umbrella. Note the name difference:
hurd-cross vs cross-hurd. As of current these scripts include up-to-date
versions of all packages used, with git versions of mig, gnumach and hurd.

(The scripts of hurd-cross were based on the work by Flavio in 2019, thank you
Flavio. However they have diverged considerably since then, and are not easily
merged into his work at github)

Good luck!

I've been looking into this problem a little further: You need the attached
patch: libstdc++-hurd.diff, at least for gcc-11 and gcc-12 (and probably gcc-13
too)


Good luck!

[-- Attachment #2: libstdc++-hurd.diff --]
[-- Type: text/x-patch, Size: 1835 bytes --]

This is notably needed because in glibc 2.34, the move of pthread functions
into libc.so happened for Linux only, not GNU/Hurd.

The pthread_self() function can also always be used fine as it is on
GNU/Hurd.
