seems like the virtual memory exhaustion is fixed in the newest version.
We have to bootstrap again (mainly for librsvg and firefox).

maybe we have to resort to cross-compiling rust in the end..

For instance xauth cannot find libXext.so.6.

Assertion 'close_nointr(fd) != -EBADF' failed at src/basic/fd-util.c:76, function safe_close(). Aborting.

The temporary workaround is to comment out ‘pam_system.so’ in system-auth and system-login..

llvm13-libs is needed in libEGL (but the browser starts and works also without EGL support).

this one is harmless most likely:

(midori:6483): GLib-GObject-WARNING **: 08:14:57.679: ../glib/gobject/gbinding.c:467: Unable to convert a value of type gpointer to a value of type CairoSurface

this makes sure no tabs and URLs open:

** (midori:6483): CRITICAL **: 08:14:58.151: session.vala:290: Failed add tab to session database: Invalid type '(null)' in statement:

                VALUES (:crdate, :tstamp, :session_id, :uri, :title)

Let’s try a rebuild of midori first.. maybe later vala or some database layer for vala..
..or the error is deep in gobject-introspection..

Amazing code quality

ISO segfaults when pacstrapping.

Several (if not all) build slaves show key verification errors.

I don’t think, it’s the keys, but gnupg slowly failing us on 32-bit.

Workaround as always: SigLevel=Never

Trick question (and possibly bonus points): what to do, if gnupg cannot be fixed..

We can ommit the tests..

Also lto is not good (breaks early) and you need lots of memory and swap to build it.

/init: line 477: mount: Value too large for defined data type

At least ISO 2022.04.03 is affected..

Bootstrapping rust via rust159-bin leads to:

error[E0463]: can't find crate for `std`

error[E0463]: can't find crate for `core`

error[E0463]: can't find crate for `compiler_builtins`

Basically, rust is broken.

Happens for instance when starting mpv.

scp -rC user@server:directory .
\033[?2004lD0711 0 directory

Enabling -vvv just makes scp hang.

No clue, what the problem could be here..

This could be bad because our librsvg (the Rust one) lags behind and librsvg-og might not
implement new stuff (for i486).

This is just the sad state of what people do to working software:

if(CMAKE_SYSTEM_PROCESSOR STREQUAL "i686" AND HAVE_STACKREALIGN_FLAG)
    add_compile_options(-mstackrealign)
endif()

which results in nasm to fail with “unknown option -m”

a) they rewrite half of the build system without apparently understanding fully the autoconf part
b) they don’t bother to delete to autoconf part
c) they write code for porting the software apparenty without testing (why bother then in the first place?)

      |         ^

Also on i486 symbols are missing if not using LTO and probing of libraries like x264/x265 fail.

no task description

kernel issue with some network card and/or
systemd subservice not working add all

I cannot login remotely or locally.

System drops to maintainance shell..

Not a single systemd subdaemon is working..

This also effectively kills all i486 build machines..
