gcc-snapshot: FTBFS on hurd-i386 (and other archs?)

2023-01-16 Thread Svante Signell via Gcc-bugs

Source: gcc-snapshot

Hi,

gcc-snapshot in sid FTBFS on hurd-i386 due to that some patches are not
applied when building gcc-snapshot. After the statement in rules.patch
ifeq ($(single_package),yes)
  debian_patches =
endif
previously defined patches are cleared, causing the build failure, see
below.

debian/ files causing the problem:

debian/rules.defs:
ifneq (,$(findstring gcc-snapshot, $(PKGSOURCE)))
  single_package = yes
  trunk_build = yes

debian/rules.patch:
ifeq ($(single_package),yes)
  debian_patches =
endif

Thanks!

gcc-11: FTBFS on hurd-i386

2023-01-03 Thread Svante Signell via Gcc-bugs

Affects: gcc-11, gcc-snapshot
X-Debbugs-CC: debian-h...@lists.debian.org

Hi,

gcc-11-11.3.0-10 in sid FTBFS on hurd-i386 due to failing linkage of
pthread_once (same error already fixed in gcc-12 and gcc-13):
/<>/build/i686-gnu/libstdc++-v3/include/i686-gnu/bits/gthr-
default.h:700: undefined reference to `pthread_once'
and more.

The patch at hand is: libstdc++-hurd.diff, attached here for convenience.

Thanks!

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.

Hi,

pthread_once (same error for gcc-11, gcc-12, gcc-snapshot):
/<>/build/i686-gnu/libstdc++-v3/include/i686-gnu/bits/gthr-

Patches have already submitted upstream by Samuel Thibault in August and
September, see
https://gcc.gnu.org/pipermail/gcc-patches/2022-August/600469.html
https://gcc.gnu.org/pipermail/gcc-patches/2022-September/601754.html

Unfortunately upstream is not very responsive. Therefore I have taken the time
to send these patches to Debian in the mean time.

Patches extracted and attached from that mail message are:
1.diff-6.diff. Note that 1.diff does not apply to gcc-12, it is related to the
git repo. This is reflected in attached debian_rules.patch by commenting out
1.diff.

Just a reflection: Matthias you are really doing a great job with the
gcc releases: Kudos!

Thanks!

Hi again,

Attached are patches to successfully build gcc-12-12-20220214-1 from source:

debian_rules.patch.patch: Adds hurd-specific patches to to debian/rules.patch.
gcc_config_gnu.h.diff: Re-enables split-stack support.

The patches below are needed for a successful build of libgo.so.21.0.0:
libgo_go_net_unixsock_readmsg_cloexec.go.diff
libgo_go_runtime_netpoll_hurd.go.diff
libgo_go_runtime_os_hurd.go.diff
libgo_go_syscall_exec_bsd.go.diff
libgo_go_syscall_exec_hurd.go.diff
libgo_go_os_user_cgo_listgroups_unix.go.diff
libgo_go_os_user_getgrouplist_unix.go.diff
libgo_go_internal_testenv_testenv_unix.go.diff
libgo_go_os_exec_internal_fdtest_exists_unix.go.diff

Makefile.in.diff: This patch is modified from the upstream patch
src_Makefile.in.diff since the Debian-specific patch gm2.diff makes changes to
src/Makefile.in before Makefile.in.diff is applied.

All patches have been submitted upstream in 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104290

The patch, libgo_go_net_unixsock_readmsg_cloexec.go.diff, has already been
committed upstream by Ian.

Thanks!

gcc-12-12-20220206: FTBFS on hurd-i386

2022-02-10 Thread Svante Signell via Gcc-bugs

Source: gcc-12
Version: 12_12-20220206-1
Severity: important
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd

Hi,

gcc-12-12-20220206 in experimental FTBFS on hurd-i386 due to missing
patches for gccgo, gnu.h and an yet unresolved bug in src/Makefile.in.
Attached are patches needed for a successful build.

This bug has been reported by Mathias and assigned upstream, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104290
but no patches are yet committed.

debian_rules.patch.patch patches debian/rules.patch to include the two
patches: gcc_config_gnu.h.diff fixing the split-stack problem when
building gotools and libgo_go_net_unixsock_readmsg_cloexec.go.diff
fixing the build of libgo. The last patch src_Makefile.in.patch, is for
src/Makefile.in moving 
all-target-libgo: maybe-all-target-libbacktrace
all-target-libgo: maybe-all-target-libatomic
outside of the
@unless gcc-bootstrap
@endunless gcc-bootstrap
pair. This patch is not part of the debian_rules.patch since I'm unsure
if this a patch is needed for all architectures or GNU/Hurd only.

BTW: Creating a new src/Makefile.in by
(cd src; autogen Makefile.def) does still create a buggy Makefile.in.
The reason of why some dependencies are within the @unless/@endunless
pair is still unknown. configure{,.ac} has the following note:

# Do not nest @if/@endif or @unless/@endunless pairs, because
# configure will not warn you at all.

Googling around did not help much, I've found no documentation of it's
use and how to encounter it.

Just a reflection: Matthias you are really doing a great job with the
gcc releases: Kudos!

Thanks!
