So far we've gotten away with using GCC 11 for Lagom and to compile the
toolchain, but via #15795 we discovered a compiler bug that has been
fixed in the latest version but would error the build with CI's GCC 11.
Time for an upgrade :^)
We already use ubuntu-22.04 images in most places, so this is pretty
straightforward. The only exception is Idan's self-hosted runner, which
uses Ubuntu Focal. LibJS should build fine with GCC 11, still.
This commit bumps the required QEMU version to 6.2 and updates the
version checking logic in Meta/run.sh to support checking against
major and minor version numbers instead of checking against the major
version only
The qemu-emulators-full package installs qemu backends for *all*
supported architectures, but we only need x86 and AArch64.
This decreases the installed size of dependencies by 800 MiB.
Apparently, qemu-system-* changed its name.
On Debian/Ubuntu, genext2fs does not make a difference: The only user of
this command, Meta/build-image-qemu.sh, runs as root anyway, and tries
to do 'mount _disk_image mnt/' first. Debian/Ubuntu always have drivers
for ext2 available, so this command has no good reason to fail, and
trying to use genext2fs might only obscure any problems that mount
encountered.
Finally, Debian Bullseye (released 2021-08-14) contains gcc-10, so the
instructions on how to upgrade are now obsolete.
After setting up the toochain on manjaro linux (new install) the build
of the toolchain failed as unzip was not found. The unzip package is
listed in the documentation for debian (apt) but is was missing for arch
linux.
Serenity build tooling autodetects gcc 10 so update-alternatives
is not necessary. Also, switching apt repositories on the fly can
cause issues with dependencies, package downgrades and leave the
system in a broken state.
This removes the '$' character so that it is easier to copy commands
directly from the build instructions and then executing them without
first having to remove the '$' character.
Components are a group of build targets that can be built and installed
separately. Whether a component should be built can be configured with
CMake arguments: -DBUILD_<NAME>=ON|OFF, where <NAME> is the name of the
component (in all caps).
Components can be marked as REQUIRED if they're necessary for a
minimally functional base system or they can be marked as RECOMMENDED
if they're not strictly necessary but are useful for most users.
A component can have an optional description which isn't used by the
build system but may be useful for a configuration UI.
Components specify the TARGETS which should be built when the component
is enabled. They can also specify other components which they depend on
(with DEPENDS).
This also adds the BUILD_EVERYTHING CMake variable which lets the user
build all optional components. For now this defaults to ON to make the
transition to the components-based build system easier.
The list of components is exported as an INI file in the build directory
(e.g. Build/i686/components.ini).
Fixes#8048.
PR #7970 added a line clarifying the requirement for QEMU 5.
Unfortunately, this location this line was added changed the meaning
of the following line, referencing the availability of GCC in Ubuntu
20.04.
QEMU 5 is not available in Ubuntu 20.04, so this change is incorrect,
as well as misleading.
This option replaces the use of ENABLE_ALL_THE_DEBUG_MACROS in CI runs,
and enables all debug options that might be broken by developers
unintentionally that are only used in specific debugging situations.
When debugging kernel code, it's necessary to set extra flags. Normal
advice is to set -ggdb3. Sometimes that still doesn't provide enough
debugging information for complex functions that still get optimized.
Compiling with -Og gives the best optimizations for debugging, but can
sometimes be broken by changes that are innocuous when the compiler gets
more of a chance to look at them. The new CMake option enables both
compile options for kernel code.
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
If you don't need/want to use Fuse+ex2 then half of the existing
install command is unnecessary, and it's hard to pick out which you
do and don't need to, for example, build Lagom. This makes it clear
which commands you can skip if you don't need ex2 support.
- Fix headings
- Consistent & more accurate code block language specifiers
- Add some newlines where appropriate
- Remove the strange "run ninja but actually you don't have to run ninja
as ninja install takes care of that" part
- Don't repeat specific build commands in "Ports" section
- Reword "Keymap" section to more generic "Customize disk image"
