Alpine made some minor modifications to the gcc aport, without
changing the version. Let's adjust the pmaports too, so we stay in
sync. [ci:skip-vercheck]
Related: 97a2b093b1
The last update of the binutils-* pmaports were not made with the latest
pmbootstrap version, which has the additional empty line remved in the
generated aports. Fix this, so we get an empty diff when running
aportgen, unless the binutils version was changed in Alpine.
[ci:skip-build], [ci:skip-vercheck]
[ci:skip-build]: will not finish in time and does not build with --strict
because of an abuild bug that will be fixed in the next abuild release by
this patch:
c54d39d8aa
Rebuild all other GCC packages against mpfr4, so they don't fail with:
Error loading shared library libmpfr.so.4: No such file or directory (needed by /usr/gcc4/libexec/gcc/x86_64-alpine-linux-musl/4.9.2/cc1)
[ci:skip-build]: won't finish in time
Related: 2b32ed3a48786fa151cad8f920e5d9997bee94ed in Alpine's aports.git
Rebuild to make it use the new armhf triplet. Otherwise cross compiling
with crossdirect to armhf fails with:
ERROR: crossdirect: failed to execute /native/usr/lib/ccache/bin/armv6-alpine-linux-muslgnueabihf-gcc: No such file or directory
This finally fixes#295.
Rebuild to make it use the new armhf triplet. Otherwise cross compiling
with crossdirect to armhf fails with:
ccache: error: Could not find compiler "armv6-alpine-linux-muslgnueabihf-gcc" in PATH
Related: #295
Upgrading binutils-armhf was blocked, after the armhf triplet had been
renamed and gcc-armhf still had the old triplet. Now gcc-armhf was
upgraded. When trying to the upgraded build gcc-armhf with the current
set of binary packages, without updating binutils-armhf, it fails with:
configure: error: cannot compute suffix of object files: cannot compile
So let's upgrade binutils-armhf too and finally have the triplet of both
programs in sync again \o/
Related: #295
Make the version match Alpine's gcc again. Fixes libstdc++ unsatisfiable
constrains related error messages (because the libstdc++ generated by
these cross-* packages has the same pkgver and pkgrel again as the one
provided by Alpine's gcc package).
[ci:skip-build]: won't finish in time
The upstream compat test case will still fail after this, there are more
issues that need to be resolved. I'm on it.
Latest version from Alpine. I've checked that we can still compile
packages for armhf after this update, in other words that we don't get
a regression related to the triplet change like in #295.
This reverts commit 593fe01bb8.
Binaries in binutils-armhf etc. break the build system:
Error loading shared library libopcodes-2.32.so: Exec format error (needed by /usr/bin/as)
Error loading shared library libbfd-2.32.so: Exec format error (needed by /usr/bin/as)
Error loading shared library libz.so.1: Exec format error (needed by /usr/bin/as)
Error relocating /usr/bin/as: bfd_errmsg: symbol not found
Error relocating /usr/bin/as: deflateEnd: symbol not found
Error relocating /usr/bin/as: bfd_arch_bits_per_address: symbol not found
Error relocating /usr/bin/as: bfd_set_error_program_name: symbol not found
Error relocating /usr/bin/as: xcalloc: symbol not found
Reverting for now. The upstream compatibility CI test is expected to fail.
The postmarketOS binary repositories still have the old binutils package.
I'm analyzing this issue in #295.
[ci:skip-vercheck]: package downgrade
This package should use the pmb:strict option, in order to force
pmbootstrap to always build it in strict mode. Otherwise it can have
a conflict with packages installed earlier.
I've just noticed that the merged patch was still using the early name
of the option, "pmbootstrap-strict". It was later changed to
"pmb:strict" in the related pmbootstrap!1771 merge request, for
consistency with !pmb:kconfig-check. Fix grub-x86 to use the proper
option name.
[ci:skip-vercheck]: version bump not needed
Adjust the depends of the GCC-8 cross compiler packages after the change
from pmbootstrap!1778. This does not have any effect (since the GCC-8
aports don't have !tracedeps in options, in contrary to the other GCC
aports we ship). But it makes sure that we don't get any changes after
running the repository maintenance script from here:
https://wiki.postmarketos.org/wiki/Repository_maintenance
[ci:skip-build]: cosmetic change, build would take too long anyway
Explicitly depend on mpc1. Our generated gcc aports use the !tracedeps
option, so we need to explicitly set the libraries it depends on.
This has mostly not been an issue, as we are installing our gcc
packages together with Alpine's gcc package, which causes the libraries
to get installed anyway.
Fixes#236.
[ci:skip-build]: takes too long to build.
Cross linker (e.g. ld from binutils-armhf) does not support any method
of setting additional link paths, and this causes problems when building
various packages. Work around this problem by calling the qemu binary
instead of the cross binary from the native chroot, whenever we are
linking.
I have tested that this allows successfully building hello-world,
coreinfo, libhybris for armhf. So this fixes#227 and fixes#228.
Regarding performance, this is the same way as distcc does it. We would
get a performance gain if we were able to use the cross-linker. But so
far I could not figure out how to patch the binutils source to make it
work like we want to have it. Maybe I'll ask on some binutils mailing
list for advice. In the meantime, this workaround should make
crossdirect work for all use-cases, and it is still faster than the
previous distcc setup, because we can avoid the overhead of setting up
and running a ssh server locally to work around missing authentication
in distcc (see pmbootstrap!1649). Let's test this for some more time,
and then make a pmbootstrap release that rolls out crossdirect for
everyone.
This device is x86_64 and has a 32-bit UEFI, so I need to install
32-bit grub (AFAIK it's the only bootloader capable of loading a 64-bit
kernel from 32-bit).
The grub-efi-x86 package has been generated with pmbootstrap.
Instead of running compilers directly, let them go through the native
ccache binary. Note that it will still use the foreign arches cache dir
because the native cache dir would be at /native/home/pmos/.ccache.
Use execve instead of setenv and execv, because that didn't work with
LD_LIBRARY_PATH (ccache was complaining that it couldn't load zlib).
Enable -Werror, because we are maintaining this program and it helps
us catching bugs early.
Create symlinks for all supported arches (armhf, armv7, aarch64, x86_64,
x86), not only armhf and aarch64. Skip creating symlinks for the arch
that the package gets built for, so we can include x86_64 in the list
without conflicting with the ccache package from Alpine.
Link to ../../../bin/ccache instead of /usr/bin/ccache, so it works
properly with crossdirect (where we mount the native chroot to /native
in the foreign chroot).
Add symlinks for clang and clang++.
A set of wrapper executables that launch native cross compilers inside
foreign chroots. Speeds up cross compilation a lot, compared to the
distcc-sshd method.
Make it possible to build old kernels with gcc4 for armv7 and aarch64.
The packages have been generated with (as usually):
$ pmbootstrap aportgen gcc4-aarch64 gcc4-armv7
[ci:skip-build]: I have tested that this builds locally.
Fixes#193.
Successfully tested both the gcc4 compiler on x86_64 with a simple
program (fbdebug) and the gcc4-armhf cross-compiler to build a very old
u-boot port for Galaxy Nexus (a MR will follow soon) which failed to
boot with either newer version (6 and 8).
